Implements #257 in full. just check green, 1510/1510 after the review pass and the rebase onto main.

#257 asks whether gtin stays mandatory. The answer is in its second comment: option 3, the full identifier enum, taken 2026-09-12, explicitly not the option 2 the issue body recommends — recorded there so nobody implements option 2 believing they are following the plan. This is option 3.

What changed

pub gtin: Gtin becomes pub product_identifier: ProductIdentifier on all eleven typed payloads.

Variant EN 18219 scheme External dependency
Gs1 { gtin } 1, GS1 Digital Link a GS1 Company Identification Number
IdentificationLink { url } 2, EN IEC 61406-1/-2 none — self-issuing
Did { did } 3, W3C DID v1.0:2022 none — self-issuing

A GTIN was structurally mandatory, so an operator without GS1 membership could not create a passport at all — not a degraded one, not one with a warning. Annex B Table B.4 sets the prerequisites side by side: every scheme needs a registered web domain and scheme 1 additionally needs the CIN. A choice of issuer was being expressed as a compile error.

Stored documents read forward, and it is tested

One lens per product group wraps a stored gtin as a scheme 1 identifier. Total, not lossy: every record written against a previous version carried a GTIN because the schema required one, and a GTIN is a scheme 1 identifier — nothing invented, nothing dropped.

schema_compat.rs's frozen fixtures — one per (product group, version), including every pre-existing one — all still read through Passport::from_stored. That is the check that exists because TextileData.gtin becoming required once cost 244 of 276 passports, and it is green.

Read sites did not have to change, by design

ProductGroupPayload::gtin stays, as a default method derived from product_identifier(). So the ~32 call sites that only want a GTIN kept compiling, and now correctly answer None for the self-issuing schemes.

🚨 That None now means two things — "no identifier" or "scheme 2 or 3". A caller reading it as not a product is wrong, and the trait doc says so. product_identifier() always answers.

Three lens gaps this exposed, which predate it

electronics 1.0.0→1.1.0, electronics 1.2.0→1.3.0 and furniture 1.1.0→1.2.0 were missing from the catalogue already. They did no harm while a record's shape happened to survive the jump, and the compat check only fails on a version whose final hop is missing — so a broken middle stayed invisible until this made the last hop mandatory for every group.

Added, each carrying its own regulatory motivation. The furniture one refuses a productType of mattress: v1.2.0 removed it because the ESPR working plan ranks mattresses as their own product group, and no furniture type describes that product, so reclassifying it would misdescribe the goods.

Scope, honestly

  • 11 new schema versions, derived from their predecessors so the diff reads as a swap rather than a rewrite; registered in embedded.rs and each product-group manifest.
  • 11 new frozen fixtures, via just freeze-schema-fixtures.
  • AAS projection: the gtin submodel property becomes productIdentifier; goldens regenerated with UPDATE_AAS_FIXTURES=1 and the diff read before committing.
  • gtin_enforcement.rs — the structural tripwire now guards product_identifier: ProductIdentifier. The check digit is validated one level further in, so losing the type would lose the validation without losing a field, which is the same silent failure the file was written for.
  • SCHEMA-CHANGES.md regenerated.

Two limits, recorded rather than left to be found

  • Scheme 2 is deliberately under-validated. EN IEC 61406's format rules are not applied here, so passing this check is not a conformance claim. The value is checked only to be an absolute http(s) URL carrying a real authority.
  • Scheme 1's ASC MH10.8.2 branch is not modelled. Nothing here issues one, and an unused variant would be a guess at a shape.
  • The read-path gap raised in review is closed. Deriving Deserialize built the scheme 2 and 3 arms field-by-field and never called the constructors, so a stored identifier that could not have been built read back happily. Deserialisation now routes through them — closed here rather than left to the change that first persists one, since this branch introduces the field and no such document exists yet.

One thing I did not do, and it is a finding

The schema prose wanted to cite Commission Implementing Decision (EU) 2026/1736 — the act that cites the six DPP standards. prose_citation_tests derives a CELEX from prose and knows only Directive (L) and Regulation (R): it resolved 2026/1736 to 32026R1736, which is wrong. The act is a Decision, 32026D1736 — the CELEX dpp-vocab already records correctly.

Rather than enshrine a wrong CELEX or half-fix a gate mid-release, the description now cites the ESPR's own Art. 41(2) presumption by act number and leaves the Decision to the type's documentation. The gate cannot express a Decision at all — worth its own issue.

Closes #257.

📝 Walkthrough

Walkthrough

Adds the public ProductIdentifier model with GS1, HTTP(S) identification-link, and DID schemes. It replaces product-group GTIN fields, adds schema versions and compatibility lenses, updates AAS projections and fixtures, and validates the new wire representation.

Changes

ProductIdentifier migration

Layer / File(s) Summary
Identifier contract and validation
crates/dpp-domain/src/identifier/..., crates/dpp-domain/src/lib.rs
Adds typed GS1, identification-link, and DID variants with constructors, errors, accessors, serde support, and tests.
Product-group payload model
crates/dpp-domain/src/product_group/data/..., crates/dpp-domain/src/product_group/payload.rs
Replaces direct gtin fields with product_identifier: ProductIdentifier. The legacy gtin() accessor now returns a value only for GS1 identifiers.
Schema versions and contracts
crates/dpp-domain/product-groups/*.json, crates/dpp-domain/schemas/**/*.json, crates/dpp-domain/src/schemas/embedded.rs
Adds current schema versions for product groups. The schemas require a closed productIdentifier union of GS1 GTIN, absolute HTTP(S) URL, or supported DID.
Compatibility lenses
crates/dpp-domain/src/schemas/lens/builtin.rs, crates/dpp-domain/src/passport/from_stored_tests.rs
Converts stored legacy GTIN fields to GS1 productIdentifier objects and adds missing schema-version transformations.
Projections, fixtures, and validation
crates/dpp-aas/..., crates/dpp-tests/..., crates/dpp-domain/tests/fixtures/..., benches/..., docs/architecture/SCHEMA-CHANGES.md
Updates AAS output, examples, benchmarks, test fixtures, compatibility tests, structural enforcement, and schema-change documentation to use productIdentifier.

Priority: ➖ Normal

Estimated code review effort: 5 (Critical) | ~90 minutes

Change: Feature

Merge Risk: 🟠 High · up to 80a92

Alternative identifiers can lose their matching identity, malformed identifiers can enter the model, legacy battery records may not migrate, and new schemas or examples can resolve against the wrong version. These issues should be fixed before merge.

Explanation

Docstring coverage is 56.38% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 94 functions across 45 files. (46 skipped: 46 unsupported.)

Full details: Publication Boundary

Explanation

The change introduces pricing and commercial-term statements into published content. CHANGELOG.md:115 says a GS1 Company Identification Number is “a paid subscription”; CHANGELOG.md:120-125 adds “GS1 membership,” “cost argument,” and “commercial position.” The same content appears in crates/dpp-domain/src/identifier/product_identifier/scheme.rs:29-33 and twice in each of the 11 new public schema files. The pull request description also calls GS1 membership a “recurring commercial subscription” and refers to an “annual bill.” These statements match the explicit pricing or contract-term failure condition. No ADR reference or non-public repository arrangement was needed for this finding.

Resolution

Remove the payment and commercial-term wording from the pull request description, CHANGELOG.md:115-125, crates/dpp-domain/src/identifier/product_identifier/scheme.rs:29-33, and the repeated descriptions in all 11 new schemas. Keep only the technical distinction: scheme 1 uses a GS1 Company Identification Number, while schemes 2 and 3 are self-issuing. Cite EN 18219:2026 Clause 5.1 and Annex B Table B.4 as the primary source. Do not mention paid subscriptions, membership, cost, annual bills, or commercial positions.

Derived Deserialize creates invalid IdentificationLink and Did variants without calling their constructors. This invariant violation affects every downstream user of the public type. Repository-local persistence is not a prerequisite.

Validate the URL authority instead of only its prefix.

This check accepts values such as https:///p/1 and https://?query. The suffix is nonempty, but neither value contains a host. This contradicts the documented absolute URL contract.

Use a standards-compliant URL parser. Require an http or https scheme and a nonempty host. Add these near-miss values to the rejection test.

W3C DID Core 1.0 syntax ABNF method-specific-id idchar official

💡 Result:

<search_synthesis>
In the official W3C Decentralized Identifiers (DIDs) v1.0 specification, the ABNF syntax for method-specific-id and idchar is defined as follows [1][2]: method-specific-id = *( idchar ":") 1idchar idchar = ALPHA / DIGIT / "." / "-" / "_" / pct-encoded The pct-encoded rule is further defined as: pct-encoded = "%" HEXDIG HEXDIG These rules are part of the DID Syntax ABNF, which uses the syntax specified in [RFC5234], with ALPHA and DIGIT referring to their standard definitions, and any rule names not explicitly defined in the DID Core specification being defined in [RFC3986] [1][2]. Earlier working drafts of the specification did not include pct-encoded in the idchar definition [3][4][5], but it was added in later versions leading up to the final recommendation [6][7][8].

Reject invalid DID Core syntax.

ProductIdentifier::did documents W3C DID v1.0:2022 syntax, but it checks only the prefix, supported method, and nonempty method-specific identifier. The W3C grammar excludes raw spaces and malformed percent-encoded sequences, so values such as did:web: are accepted even though they are invalid DIDs.

Add a local generic DID Core grammar check before constructing Self::Did. Return ProductIdentifierError::NotADid for syntax failures. Add rejection tests for did:web: and malformed percent-encoded values. A new parser dependency is not required; method-specific validation remains separate.

@coderabbitai review

Rewritten from the type-only first half into the full #257 feature — 91 files. The parts worth a close read:

  1. the lens (schemas/lens/builtin.rs, gtin_to_product_identifier) — it is what keeps every stored passport readable, and schema_compat.rs's frozen fixtures are the proof;
  2. the trait default on ProductGroupPayload::gtin, which is why ~32 read sites did not change and why None there now has two meanings;
  3. the three lens gaps this exposed, which predate it.

@LKSNDRTMLKV I will review the full feature. I will focus on lens compatibility, ProductGroupPayload::gtin default behavior, frozen fixture coverage, and the three pre-existing lens gaps.

🟠 Major · Update the hardcoded textile schema versions. · passport_to_aas.rs:100

crates/dpp-aas/examples/passport_to_aas.rs:100
🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Update the hardcoded textile schema versions.

Both examples serialize productIdentifier but retain legacy textile schema versions. The catalog current version is 1.3.0, and no constructor replaces these stored values. Version-aware consumers resolve the exact declared version; the 1.0.0 and 1.1.0 schemas require gtin instead of productIdentifier, so validation against the declared version can reject these passports.

  • crates/dpp-aas/examples/passport_to_aas.rs#L100-L100: set the textile schema version to 1.3.0 or derive it from ProductGroupCatalog.
  • crates/dpp-domain/examples/create_passport.rs#L108-L108: set the textile schema version to 1.3.0 or derive it from ProductGroupCatalog.

🟡 Minor · Use current schema versions in the access-policy assertions. · battery_end_to_end.rs:260-261

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Use current schema versions in the access-policy assertions.

This test selects battery policy 2.6.0, while the manifest current version is 2.7.0. The textile end-to-end test similarly selects 1.2.0 instead of 1.3.0 at crates/dpp-tests/tests/textile_end_to_end.rs:188-189. Update these two lookups.

base_passport already canonicalizes recognized versions to the current catalog version, so the cited battery and textile constructors, including battery_case, already use the current effective schema versions.

In `@CHANGELOG.md`:
- Line 115: Update the EN IEC 61406 limitation entry in the changelog to remove
the licensing-status statement; replace the clause “which this project does not
hold —” with a sentence break while preserving the format and URL-only
validation details.

In `@crates/dpp-domain/product-groups/electronics.json`:
- Line 10: Update the notes in crates/dpp-domain/product-groups/electronics.json
at lines 10-10 to describe v1.4.0 as current and remove “(current)” from the
v1.2.0 sentence; apply the corresponding update in
crates/dpp-domain/product-groups/furniture.json at lines 10-10 so v1.3.0 is
current and v1.2.0 no longer has that marker.

In `@crates/dpp-domain/schemas/aluminium/v1.2.0.json`:
- Around line 3-5: Update the "$id" and "title" headers in each listed new
schema file—aluminium, battery, construction, detergent, electronics, furniture,
mattress, steel, textile, toy, and tyre—so their version strings exactly match
each respective filename, including the aluminium schema's v1.2.0 identity.

In `@crates/dpp-domain/src/product_group/data/aluminium.rs`:
- Line 12: Update the public documentation for product_identifier to describe it
as a multi-scheme product identifier, not GTIN-only, in
crates/dpp-domain/src/product_group/data/aluminium.rs:12-12,
construction.rs:11-11, detergent.rs:28-28, electronics/data.rs:25-25,

crates/dpp-domain/src/product_group/data/unsold_goods/report.rs:116-116, replace
“GTIN above” with wording referring to the product identifier.

In `@crates/dpp-domain/src/product_group/data/battery/data.rs`:
- Line 55: Update the documentation for the product_identifier field in the
relevant battery data structure to describe that it may contain a GS1
identifier, an Identification Link, or a DID instead of only a 14-digit GTIN.

In `@crates/dpp-domain/src/product_group/payload.rs`:
- Around line 48-51: Update ProductIdentity::from_passport to use
ProductGroupData::product_identifier() for presence and identity construction
instead of the GTIN-only ProductGroupData::gtin() projection, preserving
scheme-aware ProductIdentifier::IdentificationLink and ProductIdentifier::Did
values as identity keys while retaining GTIN handling.

In `@crates/dpp-domain/src/schemas/lens/builtin.rs`:
- Around line 147-158: The battery lens registry must include hops from versions
2.0.0, 2.1.0, 2.2.0, and 2.3.0 to 2.4.0 so stored manifests can continue through
the existing chain to 2.7.0. Add the missing entries alongside the existing
battery `Lens::new` registrations, reusing the appropriate migration behavior
for each transition.

Update stale $id and title in all new schema versions. The new schema files retain their predecessors' version headers. Update the headers in the aluminium, battery, construction, detergent, electronics, furniture, mattress, steel, textile, toy, and tyre schema files so each $id and title matches its filename version. Consumers that use $id as schema identity can otherwise treat a new document as its predecessor, and each title identifies the wrong version.

Update stale GTIN-only documentation after the ProductIdentifier migration.

The new type also permits Identification Link and DID values. Public API documentation must not describe it as GTIN-only or refer to the removed gtin field.

Preserve scheme 2/3 identifiers in ProductIdentity.

ProductIdentity::from_passport calls ProductGroupData::gtin(), which returns None for valid ProductIdentifier::IdentificationLink and ProductIdentifier::Did values. These passports therefore produce no identity key, so import matching can treat them as having no identity. Use product_identifier() for the presence check and make ProductIdentity retain a scheme-aware identifier instead of relying on the GTIN-only projection.

Add the missing battery lens hops. The battery manifest registers versions 2.0.0, 2.1.0, 2.2.0, and 2.3.0, but the lens registry has no hops from those versions to 2.4.0. A stored document at any of these versions cannot reach the current 2.7.0 schema through the registered battery lens chain.

Review worked — 10 applied, 1 declined with a follow-up

Pushed as d8242dd. just check is green (1456 tests). Every claim below was
checked against the code before being believed; where a finding was right about
more than it named, the sweep went wider than the listed sites.

Applied

Commercial terms in published documentation (scheme.rs#L29-L33). Right to
remove, though not as a disclosure of anything of ours — it is an unverified
claim about a third party's terms, sitting in a compliance-pinned doc comment
where it can go stale with no one watching. The standards-based prerequisite
comparison is what carries the argument and it stays: every clause 5 scheme
needs a registered web domain, scheme 1 additionally needs a GS1 Company
Identification Number (Annex B, Table B.4).

The finding named two lines; the same wording was in 13 more published
surfaces
— the CHANGELOG variant table and its "settles the cost argument"
sentence, and two sites in each of the eleven new schema JSONs, which ship to
crates.io and are read by anything that resolves our schemas. All swept.

Constructor validation on deserialisation (scheme.rs#L54-L55). Real, and
closed rather than documented. Reading now routes through a private Wire shape
and TryFrom, so a stored identifier that ProductIdentifier refuses to build
cannot be read either.

Worth saying why it is closed here: this branch introduces the field, so no
document carrying a scheme 2 or 3 identifier exists anywhere yet. That makes
this the last moment at which tightening the read path costs nothing. Once one
is written, the same change becomes a migration. The CHANGELOG paragraph
describing it as a known gap is replaced by one describing the fix.

URL authority (scheme.rs#L112). Confirmed — https:///p/1 and
https://?query both passed. The check now takes the authority as the span up
to the first /, ? or # and requires it non-empty, and rejects whitespace
anywhere in the value. All four near-misses are in the rejection test.

No URL-parser dependency: dpp-domain builds for wasm32-unknown-unknown and
has no url crate today, a new edge in the crate graph is a reviewable change
in itself, and the type's documented claim is a shape check rather than a
conformance verdict. Adding a parser to serve one predicate would buy standards
compliance the type explicitly does not assert.

DID Core grammar (scheme.rs#L140). Confirmed. did:web: was accepted.
Implemented as suggested — a local check of clause 3.1's
method-specific-id = *( *idchar ":" ) 1*idchar, with
idchar = ALPHA / DIGIT / "." / "-" / "_" / pct-encoded, returning NotADid.
Rejection tests cover a raw space, an embedded space, a trailing colon, three
malformed % escapes and a path/query suffix; acceptance tests pin what the
grammar does admit, including a percent-encoded port and the empty
intermediate segment the ABNF permits.

Stale $id and title (schemas/aluminium/v1.2.0.json#L5). Confirmed in
all eleven. Corrected — and a test now walks the embedded table asserting every
schema's $id and title carry its own version, since the defect is produced
by copying a predecessor and will otherwise recur on the next one. Every
pre-existing schema already passes it.

Manifest notes contradicting currentSchemaVersion
(product-groups/electronics.json#L10, furniture.json#L10). Both fixed.

This one turned up something the finding did not reach: electronics v1.3.0
was missing from schemaVersions entirely
, on main, while the schema is
embedded, validated against and reachable by a lens. So
ProductGroupDescriptor — which is what a caller asks "which versions exist" —
named four of five. The catalog↔registry parity test could not see it: it
asserted every version the catalog declares is embedded, and that direction
held. It now asserts the reverse too.

Stale GTIN-only field docs (data/aluminium.rs#L12,
data/battery/data.rs#L55). All eleven payloads and the unsold_goods report
note. Also dpp-aas/src/builder.rs, which the finding did not list: its
gtin parameter is a caller-chosen asset identity by design — the
unsold-goods mapper's module note records the case that forced it — but the doc
described it as "the 14-digit GTIN". Rewritten, with the residual sharp edge
stated: the specificAssetId it populates is named gtin unconditionally, so a
caller passing a scheme 2 or 3 identifier gets it under a GS1 label. That is
pre-existing and wider than this change, and is not the passport's own
identifier — the product-group submodel emits that separately as
productIdentifier.

ProductIdentity losing scheme 2/3 identifiers (payload.rs#L51). Correct
and the most consequential finding here: from_passport read gtin(), which
answers None for a perfectly well-identified passport, so the import
delta-matcher found nothing to match and would have created a duplicate
instead of updating the record in front of it. Silent, and it corrupts the one
thing the key exists to prevent. ProductIdentity::gtin is now
ProductIdentity::identifier, built from product_identifier(). Two tests: one
that a scheme 2 or 3 passport yields a matching key, and one that a group
carrying no identifier still yields none, so the fix did not turn None into
"always Some".

Licensing status in the EN IEC 61406 limitation (CHANGELOG.md#L115).
Applied, there and in scheme.rs and all eleven schema JSONs. The limitation
now reads as what it is: EN IEC 61406 format rules are not applied here, so
passing this check is not a conformance claim.

Declined, with the reason

Missing battery lens hops (builtin.rs#L158). The observation is correct —
there is no chain from v2.0.0–v2.3.0 to v2.4.0. Not applied here, for two
reasons.

Adding the hops changes no outcome. Those versions are listed in
schema_compat.rs's expected_refusals and would stay listed: batteryType
became required at v2.5.0 because Annex VI Part A point 2 makes the battery
category mandatory public content, and the 2.4.0→2.5.0 lens refuses rather than
invent a category for a record that predates the mandate. Bridging 2.0.0→2.4.0
moves those four from "refused, no path" to "refused at the next hop". No stored
document becomes readable.

And it is not this branch's. git diff origin/main...HEAD -- crates/dpp-domain/tests/schema_compat.rs
is empty — the refusal set is byte-identical to main, which is the
evidence that nothing became newly unreadable here. This branch appends one
final hop per product group and leaves every earlier hop as it found it.

What the finding does correctly expose is that the expected_refusals comment
gives one mechanism for six entries when only two of them reach the lens it
names. Filed as #299, with the chain, the comment correction, and the question
of whether the compat check should require a complete chain rather than only a
reachable final hop — which is what would have caught this and the two
electronics gaps without anyone looking.
