How People Translate Quickly | Apache Avro Schema Docs: Translate Field Explanations Without Changing Event Data

—

by

eduKate Asia

To translate Apache Avro schema documentation quickly, edit only approved explanations such as record and field doc values, while protecting schema names, field identities, types, union branches and defaults. An Avro schema is a machine-readable contract for encoded data, not a normal document. A clear French explanation of delivery_time can help a new engineer, but renaming the field or changing its logical type may alter how an event is read. The reliable workflow inventories protected structure, translates commentary in context and compares the schema that applications actually parse.

Avro localization quality assurance has an important subtlety: the official specification’s Parsing Canonical Form strips doc attributes because those descriptions do not control data parsing. That makes documentation translation technically plausible, but it does not promise that every registry, code generator, policy engine or deployment process treats modified schema text as the same artifact. Source control may record a change, registry systems may assign new identifiers, and generated documentation may display language according to its own rules. Teams must validate both Avro semantics and operational delivery.

This guide addresses a precise job for multilingual data engineers, technical writers and classroom educators: translate the human-facing explanations embedded in an Apache Avro schema without rewriting event identity or schema evolution behavior. It covers structured extraction, worked JSON, compatibility traps, tests, failure diagnosis and a new-context exercise. It is intentionally narrower than a general introduction to Kafka or a guide to changing schemas. A schema change for new business requirements deserves separate design and approval, even when someone notices that an old English description is unclear.

Identify which part of the data pipeline needs another language

A schema can appear in a source repository, a registry, generated API documentation, a consumer’s codebase and an analyst’s data dictionary. Translating the schema text itself is only one delivery option. If engineers merely need a Chinese onboarding guide, a companion document tied to the schema revision may be more maintainable. It avoids multiplying authoritative schema copies when a single data contract is shared across services. Begin by determining who needs the language and whether the consuming software displays the doc field at all.

Sometimes the team deliberately generates multilingual documentation directly from doc, and a localized schema edition is reasonable. In that case keep one original authoritative schema and version the localized variant as a derivative. Record its locale, parent commit, compatibility expectations and distribution channel. If a deployment process registers every changed JSON file automatically, do not feed the translated variant into that pipeline without explicit engineering approval. A language team can finish accurate prose while a service registry still requires a controlled release decision.

A frequent mistake is assuming that any string in schema JSON is a translatable sentence. The name of a record or field is a program symbol. An enum symbol is a code value. A namespace contributes to type identity, and a default determines how a reader fills a missing field during schema resolution. These strings may resemble English but have operational roles. The brief should explicitly distinguish data-contract content from descriptive annotations before anyone opens a spreadsheet or translation platform.

Know the documentable surfaces and their limits

The Avro specification defines optional doc strings for records, fields and certain named types such as enums, as well as documentation for protocol constructs. Those are useful places to explain human meaning. For instance, a field description can distinguish a UTC timestamp from a local business date or explain whether a monetary amount includes tax. If the source is ambiguous, a translator should ask the data owner rather than replacing uncertainty with an invented rule. Documentation is part of how people understand data even when it is not part of the binary parsing grammar.

Avro allows additional metadata attributes not otherwise defined by the specification, provided they do not change serialized-data format semantics. This does not mean every custom attribute is a safe translation field. A project may define x-help, displayName, classification or some other extension with application-specific behavior. Inspect the consuming tools and the repository’s conventions before touching a custom attribute. A displayName used for interface copy may be suitable, while a policy tag or semantic classification key may need to remain exactly fixed.

For multilingual requirements, plain Avro doc is a string rather than a standardized language map. Putting several languages into one long doc value can make generated documentation confusing and harder to maintain. A sidecar language catalog keyed by stable schema path, or separate edition-specific documentation generated from one canonical contract, may be better. If the team chooses to localize doc in a schema derivative, label the locale externally. Do not pretend a custom doc_fr property will be understood by arbitrary Avro tooling without custom integration.

Read the schema as a typed tree, not as flattened text

An Avro schema can nest records, arrays, maps, unions, enums and logical types. The same short field name may occur in different record paths, each with a different meaning. For example, status under a shipment record might describe dispatch state, while status under a payment record might describe settlement. A spreadsheet containing only the string status would not help a translator choose the correct wording. The extraction key should include the fully qualified record name, field path and role of the text being translated.

Walk the JSON tree with a schema-aware inventory. Capture each allowed documentation property together with parent record, field name, type, default, source locale, source revision and surrounding field descriptions. For nested unions, record which named type owns a documentation string rather than confusing branch order with field order. Keep the source text and its context linked even when the same sentence appears several times. A repeated phrase can be intentionally reused, but reviewers must know which record it belongs to before approving its target-language equivalent.

As the translator works, show protected tokens in context: field identifiers, enum symbols, time-zone notation, unit names, example values and references to external specifications. A well-designed segment might say that created_at is an instant expressed in epoch milliseconds and must never be described as a locally formatted clock time. The translator can rewrite the natural-language sentence for the target audience, but the unit and field reference remain recognizable. This small amount of context prevents expensive errors in production data glossaries.

A worked record example with protected structure

Consider a simple Avro schema for a school library loan. The record’s machine identity is edu.example.LibraryLoan, its fields have fixed identifiers, and its doc values tell readers how to interpret the values. The following JSON is syntactically well-formed. The example uses a string for due_date because a real team might have legacy ISO date strings; production systems should still verify that their date representation is explicitly documented rather than assuming all systems use the same convention.

{
  "type": "record",
  "name": "LibraryLoan",
  "namespace": "edu.example",
  "doc": "A record of one library loan.",
  "fields": [
    {"name": "loan_id", "type": "string", "doc": "Stable loan identifier."},
    {"name": "due_date", "type": "string", "doc": "Return date in YYYY-MM-DD form."},
    {"name": "renewals", "type": "int", "default": 0,
     "doc": "Number of times this loan has been renewed."}
  ]
}

In a Malay documentation edition, the three doc strings can explain the same meanings in Malay while preserving LibraryLoan, edu.example, each name, each type and the integer default 0. The ISO-like date pattern remains a literal contract example, not a phrase to rearrange according to local date conventions. If a translator notices that the due date actually uses a timezone-bearing timestamp in the source system, the right response is to flag a documentation defect for the data owner. Silently changing the string type or the data format would exceed a translation brief.

The most revealing comparison is not whether the edited JSON looks close to the original but whether the parsed structural schema is unchanged. The official Parsing Canonical Form removes documentation and aliases among other non-parsing attributes, while retaining fields, symbols and other elements relevant to reading serialized data. An equal canonical representation is strong evidence about parsing shape under that definition. However, preserve a stricter allowlist diff as well: some stripped attributes, notably aliases, can matter to reader-writer schema resolution and application behavior in contexts beyond canonical parsing identity.

Why renaming a field is not a translation shortcut

Suppose the source field is due_date and the target-language explanation naturally uses a word meaning ‘return deadline’. Changing the JSON field name to a translated phrase would not simply make the output bilingual. It creates a different field name that code and data readers may fail to match. Avro’s resolution rules and alias mechanism can sometimes support deliberate renaming during schema evolution, but that is a schema engineering operation requiring compatibility analysis and coordination across producers and consumers. It is not part of the safe doc translation boundary.

Likewise, do not translate enum symbols such as APPROVED, REJECTED or PENDING just because they look like ordinary English. They represent encoded alternatives, and consumers may branch on their exact values. The correct multilingual pattern is to keep each symbol stable and provide a human-facing explanation or label in a documented interface mapping. If a report needs to display ‘Approved’ in Malay, the report can translate the user-interface label without rewriting the underlying code. Schema comments should make that relationship clear enough for implementers to reproduce.

Record namespaces and qualified names deserve the same protection. Two records with matching short names can still be different types because their namespaces differ. A translator who sees the namespace as an address-like English phrase may be tempted to adapt it to a regional organization name. That can change type identity and break references, even if the record’s visible description improves. Treat namespace, named-type definitions and named-type references as a connected graph. The localization may explain that graph in another language; it must not rename graph nodes without a separate migration plan.

Keep unions, defaults and null handling out of the language layer

One of the most damaging edits is rearranging a union because its choices look like a list of words. In Avro, a union is represented by a JSON array of schemas. Branch choice and ordering matter for various encoding and default-value rules. A translator should not sort those branches alphabetically, change null into a target-language adjective or move a default from one branch to another. The safest extraction excludes the entire structural array while exposing a separate descriptive doc that can explain what the alternatives mean to a user.

The default attribute has specific schema-evolution semantics. A default for a newly introduced field can supply a value when older writer data lack that field as read through a newer schema. It does not mean the writer can omit the field at encoding time, and it is not a user-visible placeholder sentence to translate. If the default is an English-looking string, ask whether it is real business data, a sentinel value or an example. Changing it can alter records produced by schema resolution. Keep it untouched in a documentation-only translation task.

Nullability and optionality also must not be conflated. A field with union type ['null','string'] represents a value that may be null, but the existence and position of a default is a separate question. A translator can explain the difference in accessible prose; they must not insert default: null simply to make a target-language description say ‘optional’. That would be a substantive contract modification. If an original doc incorrectly calls a field optional, document the inconsistency and ask the owner to resolve it before publishing a misleading localized guide.

Protect numeric, temporal and logical type semantics

Date and time descriptions are a fertile source of translation bugs. Avro may represent a timestamp through a logical type attached to an underlying primitive type, or a legacy schema may use a string format. A translator should identify which mechanism the real schema uses, along with the intended timezone and precision, before choosing words such as date, time, instant or deadline. Never change a logical type, time unit or numeric precision because the target country uses a different display convention. Those changes belong in data modeling, not localization.

Financial data needs similar care. A decimal logical type can specify precision and scale, and a field description might say that amounts are in a particular currency or smallest unit. Translating ‘cents’ as a generic ‘amount’ loses information, but changing the scale attribute would be far worse. Preserve the type and exact numeric contract while translating the explanation faithfully. If readers need locally formatted currency, place that requirement in the display application or a derived report rather than silently modifying the raw event schema.

Units of measurement may be expressed only in docs, especially in older records. That makes those sentences important even though Avro ignores them for parsing. A description of distance_m that wrongly says kilometers can cause a consumer to multiply values incorrectly. Add unit-sensitive terms to the glossary and require a domain reviewer for conversions, bounds and denominators. Language review must protect real-world meaning as well as machine structure, particularly when a schema lacks stronger validation constraints for the concept described.

Understand Parsing Canonical Form without overclaiming it

Parsing Canonical Form is a formal normalization of schema information relevant to interpreting data. It expands applicable names, removes non-parsing attributes such as doc, orders retained attributes and normalizes certain syntax. For a documentation-only change that leaves structural elements untouched, equality of Parsing Canonical Forms is an excellent automated sanity check. Use a conforming Avro implementation to compute the forms rather than inventing a simplistic dictionary sorter. Field order, nested type resolution and other details matter to the formal transformation.

Canonical-form equality is not a universal test of application equivalence. Aliases are stripped by the specified canonicalization yet can be used during schema resolution. Custom metadata may affect governance or code generation even though it does not change the encoded bytes. A schema registry might track full schema strings or metadata differently from another tool. Consequently the release criteria should have two layers: a strict change allowlist that permits only declared documentation properties, and parsing-canonical equality that catches accidental changes to serialized-data interpretation.

Avoid treating a numeric fingerprint as a security signature or a proof of semantic accuracy. Avro recommends fingerprinting canonical forms for efficient identification, but hashes are not designed to certify that a translated sentence is scientifically or commercially true. Record the canonical result, the exact source and target files, and the tool version used to compute them. If the checks pass yet an explanation is mistranslated, the technical verification will not detect the language error. Human domain review is still necessary, and the report should say so plainly.

Separate registry policy from translation approval

In production, teams may manage Avro through a schema registry and compatibility policy. Registration can have side effects beyond parsing compatibility: a new schema version may be created, an audit record may change, or generated clients may be refreshed. A translator preparing an offline edition should not register anything simply to see whether the text appears. Use a staging environment or local parser approved by the data team. The WordPress publication workflow for an educational article is also separate from the actual schema distribution system; neither should be triggered by producing this manuscript.

The schema owner should document where localized docs live, who can update them and how they are matched to new contract revisions. If a field gains a new allowed value or its meaning changes, the translated explanation must be reviewed against that change. A translation memory is helpful, but old wording should not automatically be carried forward just because the field name matches. Record semantic change notifications and mark stale target-language docs as needing review until a knowledgeable owner approves them.

If a team insists on committing translated schema copies, define how to avoid accidental use of a localization-only file as a producer contract. Directory conventions, build exclusions and file naming can help, but the strongest guard is a test that recognizes the canonical source schema and verifies documented allowlist differences. A README alone is easy to overlook. Make the safe path easier than the unsafe path: automatic documentation generation from checked language catalogs can be preferable to manually maintaining several runnable schema documents.

Create a precise extraction contract

The extraction phase should produce one entry per approved doc occurrence with its schema path, context, source text and protected references. Export in UTF-8 and maintain segment identity across revisions. Do not include source code comments from adjacent build scripts, JSON keys or example payload values unless the translation assignment explicitly covers them as separate artifacts. A segment containing an acronym should carry its expansion, target audience and whether the acronym is to be preserved. This is especially valuable when an internal platform combines Avro with service-specific extensions.

Translators should receive examples of actual records as context but not as editable strings. Distinguish sample data from permitted documentation: a student name in an example is not a field label, and a transaction ID is not a text segment. If a description includes a JSON example, protect its syntactic tokens and embedded identifiers while translating surrounding prose. Reinsert through a JSON-aware generator and parse the resulting file again. A careless manual edit can create an invalid comma or escape sequence even when the sentence itself is excellent.

For a full-quality review, pair a language reviewer with a data-contract owner. The translator checks register, syntax, terminology and target-reader comprehension. The engineer checks field roles, allowed values, units and whether the description matches the service’s behavior. Both can work asynchronously from a shared issue list if the scope is narrow. This is more efficient than asking engineers to proofread every sentence from scratch or expecting translators to reverse-engineer serialization semantics from code snippets.

Test the localized schema on actual representative data

A parser check should be the first technical gate after reinsertion. Validate the JSON structure, then parse the Avro schema with a compatible implementation. Compare the extracted structural paths to the baseline and confirm that no field, union branch or named type disappeared. Calculate the Parsing Canonical Form with an official implementation when possible. A passed parse is necessary but not sufficient: a changed field name may still be legal Avro, so equality of approved structural representations is essential to catch a plausible-looking contract change.

Test representative records using the same writer schema and reader expectations that the application employs. Include a simple record, null-like cases where allowed, records containing special characters, values at numeric boundaries and samples from older writer versions if schema evolution is relevant. The intended result of a documentation-only localization is that deserialized data values and field mappings remain the same. If a test fails only after modifying doc, inspect whether the test harness or registry accidentally treats full schema text as a versioned deployment contract. Document that integration behavior instead of disguising it as an Avro parsing rule.

Documentation rendering must receive its own test. Generate the schema reference or help page for the target locale and inspect complete paragraphs, field tables, headings and example references. Some generators omit doc, truncate it or escape punctuation in unexpected ways. Others render documentation only on hover, making important qualifiers difficult to discover. Validate the actual output with a reader who knows the language. A schema can be structurally perfect while its translated explanation is clipped at the exact phrase that distinguishes a UTC instant from a local date.

Diagnose a canonical-form mismatch after translation

When canonical forms differ, first check whether the diff includes a new field, altered type, reordered field list, renamed record, changed enum symbols or modified nesting. None of these should occur in a pure documentation translation. Restore the protected structure from the source and reapply approved doc updates using path-based replacement. Do not try to solve the mismatch by changing the original source schema until it agrees with the localized file. The scientific equivalent of that mistake is changing the experiment to fit the translated report.

An easy-to-miss error occurs when a generic localization tool interprets a name property as a display label. JSON translation tools designed for website content may assume that keys named name or title contain human-facing copy. In an Avro record they can be symbols that define parsing identity. Configure the extractor to target explicit documentation paths rather than common English attribute names. Add a regression fixture with nested records and duplicate short field names so a tool upgrade cannot quietly reintroduce the mistake.

Another mismatch may stem from reserializing the schema through a library that normalizes or drops extension attributes. The result can still parse and even yield the same canonical form while a governance label, alias or custom metadata field has changed. That is why a strict allowlist diff remains necessary alongside canonicalization. If the serializer cannot round-trip the team’s extension fields, choose a more suitable representation or localize docs outside the schema. A tool that produces valid Avro is not automatically a safe general metadata editor.

Diagnose correct parsing but incorrect business understanding

Suppose a localized doc says discount_rate is a percentage from zero to one hundred, while the producer stores a fraction from zero to one. The Avro contract may continue operating perfectly, but a reader can multiply the value by one hundred twice when producing a report. This failure requires a domain test: select a known sample record, ask a bilingual analyst to interpret the field using only the localized explanation, then compare that interpretation with the contract owner. The problem is semantic, not syntactic, and the repair belongs in the wording unless the original contract itself is wrong.

A second semantic trap concerns event timing. processed_at, created_at and occurred_at can refer to different points in an event’s lifecycle even if every field is timestamp-like. Translate the temporal relationship in complete sentences rather than treating the words as synonyms. In a school information system, when a loan was recorded may differ from when a student actually borrowed the book. If that distinction is lost, attendance, reminders or audit reports can be wrong. Use sample event sequences to review both languages and capture ambiguous source terms as issues.

A third trap is substituting a local institutional concept for a general source term. A field named grade might mean a score, a year level or an internal classification. Translating it as an examination result because the target audience is a school can mislead. The schema path, example records and consuming application should establish the intended meaning. A translator may propose a clearer phrase, but the data owner must confirm it. The strongest localization expresses the existing meaning with less reader guesswork, rather than improving prose by creating a new domain model.

Handle revisions without losing the translation trail

On a new schema revision, compare the old and new canonical source schemas and read the engineer’s change notes. A structurally unchanged field may still have a revised description because business meaning has changed. A structurally changed field may retain the same old wording by accident. Translation memory alone cannot decide whether a segment remains valid. Build a review queue for newly introduced fields, changed docs, altered field constraints and any renamed or aliased type; link each queue item to the source commit and responsible owner.

Track translation decisions at segment level so a later reviewer can identify why one term was chosen and which examples supported it. This is particularly useful for terms such as ‘settled’, ‘posted’, ‘committed’ or ‘confirmed’ that have different operational meanings in different systems. A good record is short but evidence-based: source path, chosen target phrase, definition, reviewer and date. The method is scalable because most unchanged segments need only automated structural checks and spot review, while genuinely changed meanings receive human attention.

When consumers live in several jurisdictions, avoid assuming the regional variant of one language covers all readers. If the system uses locale-specific terminology, maintain separate approved editions or carefully designed common wording. Keep locale identification outside protected schema names, and document how the correct edition reaches its intended audience. An operator should not infer the locale from a filename fragment and risk publishing the wrong documentation. The language catalog must be managed as a publication artifact with ownership, testing and rollback, even though it does not change the underlying event encoding.

A changed-context transfer exercise: a sensor stream replaces the library record

Imagine the same team now documents an Avro stream of environmental sensor observations. The schema has a named record AirReading, a field pm25_ug_m3 with a floating-point type, a nullable quality flag and a timestamp field whose logical type represents an instant. The original English documentation says the instrument may report a null quality flag when calibration is unavailable. A new translation brief asks for Indonesian explanations and says that every numeric display must use local punctuation. Decide which fields can be translated and which formatting requests belong outside the schema.

The correct answer is to translate approved doc strings while preserving field names, numeric types, null branch structure, defaults, logical-type metadata and the encoded observations. The new language can explain that the PM2.5 measurement is expressed in micrograms per cubic metre and that null quality status does not mean the air is safe. Decimal commas, digit grouping and date presentation belong in a viewer or report, not in the Avro data contract. The translator should ask the domain owner whether the quality flag describes calibration, sensor health or data validity before choosing a definitive term.

For verification, parse original and derivative schemas, compare the strict structural diff and Parsing Canonical Forms, deserialize representative old and new records and inspect localized documentation. Test a record with a missing field resolved through a legitimate default when the version history makes that relevant. Then ask a target-language reader to interpret a sensor reading and its uncertainty without seeing the English source. This exercise transfers the method from library loans to environmental science while increasing attention to units, quality codes and missingness.

A reviewer-ready release checklist

Confirm that the inventory covers exactly the chosen schema revision and that each target sentence is mapped to a record or field documentation path. Check terminology, units, time semantics and confidence qualifiers with the data owner. Validate that code-like identifiers, enum symbols and example tokens have not been translated. Parse the generated JSON and Avro schema, and check that the doc-only allowlist diff contains no surprise modifications. Compute canonical equality with an identified tool. Record all tests and their actual outcomes rather than marking unexecuted checks as passed.

Next, inspect the published-looking output offline: field lists in the intended order, readable Unicode, complete descriptions, accessible tables, matching links and examples that still refer to valid field names. If a registry or documentation portal is part of the planned release, test it in a staging environment with permission from its owner. Do not assume production identifiers, compatibility policies or rollout behavior will remain unchanged because the binary interpretation is stable. Keep the final release decision separate from translation acceptance so both responsibilities are traceable.

Finally, preserve the canonical source file, localized derivative or sidecar, source commit reference, glossary, change log and comparison reports. Include the target language in the documentation manifest and name the engineer and linguistic reviewer. Make it possible to answer three questions later: which schema did this explanation describe, what exactly changed, and how was it checked? This is the practical definition of reproducible documentation localization. The smallest reliable package is the one another team can audit without reconstructing its authors’ intentions from scattered messages.

Limits and responsible claims

A successful schema comparison does not certify the real business meaning of every field. The original may be inaccurate, outdated or underspecified. Avro’s encoding rules say how bytes relate to a schema, not whether a description of a school deadline or medical category reflects local policy. Translators should distinguish literal source meaning from domain correctness, flag uncertainty and avoid promoting a documentation review to a legal or scientific certification. A language derivative can be excellent while the source contract still needs improvement.

Tool support also varies. Some libraries expose doc cleanly, others ignore metadata, and some registries treat documentation changes specially. This guide therefore provides a testing strategy, not a guarantee for an unnamed deployment stack. Release reports should state which Avro version, schema library, registry implementation and documentation generator were used. If those environments are unavailable, preserve the offline article and explain the untested integration instead of claiming the final production path has been verified.

Summary: translate explanations, preserve the contract

Reliable Avro documentation translation begins with a strict boundary. The human meaning in approved doc strings can be made clear for new readers, but names, namespaces, enum symbols, types, union structure, defaults and code identities remain part of the data contract. A schema-aware extractor, bilingual domain glossary, JSON and Avro parsing, strict allowlist diff, Parsing Canonical Form comparison and representative data tests offer strong evidence that the language work did not become an unintended schema migration.

The deeper lesson is that technical translation succeeds when people can trust both the words and the structure. A student should understand what a field represents, a developer should be able to deserialize the same event, and the data owner should know exactly which artifact is authoritative. These are complementary forms of accuracy. Neither a fluent sentence nor a passing parser test can substitute for the other.

Frequently asked questions

1. Can I translate the doc values in an Avro schema?

Yes, when the consuming workflow permits it and the doc strings are part of your approved localization scope. Preserve the protected schema properties and test how the changed file is distributed and rendered.

2. Why not translate field names so the JSON becomes fully multilingual?

Field names are data-contract symbols. Changing them may break producers, consumers and schema resolution. Provide translated descriptions or separate display labels instead; treat genuine renaming as a schema migration.

3. Does equal Parsing Canonical Form prove everything is unchanged?

No. It is a strong check of parsing structure under the specification, but stripped attributes such as aliases and tool-specific metadata may matter operationally. Use a strict approved-property diff alongside canonical comparison.

4. Is a field with a default value optional when writing records?

Not merely because it has a default. Avro defaults primarily matter when a reader resolves data written under a schema lacking the field. Do not rewrite default values or introduce them during documentation translation.

5. Can I translate enum symbols such as PENDING?

Not in a documentation-only change. Keep encoded symbols stable and translate their human-facing explanations or user-interface labels. Confirm that the target wording matches the actual business status.

6. What if a description says ‘date’ but the field is an epoch timestamp?

Flag the ambiguity and ask the data owner. A target-language translation should not silently change the field type or add a local timezone assumption. The source documentation may need its own correction process.

7. Do custom Avro metadata attributes support language maps automatically?

No. The standard permits non-parsing metadata, but an application’s interpretation depends on its own rules. A custom localization extension requires explicit tooling, documentation and QA.

8. Should localized schemas be registered in production for testing?

Not without approval from the schema owner. Use read-only or staging tests wherever possible. A registry may version or audit textual changes differently from the formal Parsing Canonical Form.

9. How do I test a multilingual field description with real users?

Provide a representative record, the localized description and a task requiring interpretation of units, nulls or event timing. Compare the reader’s understanding with the data owner’s intended definition.

10. Is an external multilingual data dictionary better than localized schema files?

Often, especially when one authoritative schema serves many systems. The best choice depends on how users encounter docs and how revisions are managed. Whichever approach is selected should preserve stable schema identity and traceable language editions.
