Typo3 Structured Data

TYPO3 structured data

Source: https://github.com/dirnbauer/typo3-skills

Make a TYPO3 page describe what it visibly is. Emit one coherent, testable entity graph from the same records that render the page; never maintain a second hidden editorial truth.

Contract

1. Identify the selected repository, DDEV project, TYPO3/Core version, Site bases, languages, and canonical public URLs before writing. Run Composer, TYPO3, and PHP through DDEV.
2. Inventory every existing application/ld+json, Microdata/RDFa fragment, schema extension, TypoScript/Fluid producer, page type, content element, and domain record before changing markup.
3. Derive types and properties only from user-visible, current page content. Never invent a price, availability, opening time, author, review, rating, address, job, event, or FAQ answer.
4. Prefer server-rendered JSON-LD. Use absolute canonical URLs, stable @id values, ISO-8601 dates, real language-specific URLs, crawlable images, and the most specific applicable schema.org type.
5. Keep global and page entities in one connected @graph when practical. Reuse stable identities instead of emitting contradictory duplicate Organization, WebSite, WebPage, or main-entity nodes.
6. Do not promise rankings, a knowledge panel, stars, or a rich result. Valid markup makes a page eligible for supported search features; appearance remains the consumer's decision.
7. Parse and verify the rendered output for every affected page class. A green JSON parser alone is insufficient: vocabulary, consumer requirements, visible-content parity, canonical identity, duplicates, and representative Google eligibility checks must also pass.

Upgrade graph modes

Return bounded evidence to the orchestration node; do not start an independent repeat-until-clean loop.

• Intake inventory: read only. Record existing producers, entity types, canonical @id values, eligible page/content classes, visible source fields, and current validation findings before Baseline A.
• Contract A parity: preserve the exact pre-upgrade structured meaning and rendered values. Repair only upgrade-induced breakage. Missing opportunities become P14 candidates; adding them here would change the immutable DOM contract.
• P14 enrichment: start only after Contract A closes and the track has an intent approval. Implement the approved page-type matrix, derive a B baseline, and verify that visible HTML and interaction behavior stay unchanged apart from the declared JSON-LD addition.

Select types from visible page purpose

Read type-selection.md before choosing types. Use the current Google Search gallery as a consumer-specific subset of the broader schema.org vocabulary.

FAQPage can still describe genuine visible FAQ content. Google has, however, limited regular FAQ rich-result display to well-known authoritative government and health sites. Record this limitation; do not sell FAQ markup as an expandable Google result for an ordinary commercial site. Google also removed How-To rich-result support; valid HowTo vocabulary may still describe content for other consumers, but it is not a current Google rich-result target.

Implement in TYPO3

Read typo3-integration.md before installing or changing an integration.

1. Preserve a working project-specific producer when it already yields one correct entity graph. Remove parallel generators only after proving which one owns each entity.
2. When a maintained abstraction is needed, prefer the installed-compatible brotkrueml/schema API and Fluid ViewHelpers over hand-built JSON strings. Verify its exact Composer constraint and classes against the locked installation; do not assert an API from memory.
3. If the package is missing, add it only inside the approved Composer/stateful graph node. Resolve a version compatible with typo3/cms-core:^14.3, snapshot before extension setup, and record the lockfile version, source, licence, setup command, and rollback reference.
4. Map TYPO3 records to entities at their owning boundary: Site configuration owns global identity; page/rootline data owns WebPage and breadcrumbs; EXT:news owns articles; Content Blocks or domain records own FAQ, product, event, job, recipe, review, and media facts.
5. Use one serialization boundary that safely JSON-encodes values. Never concatenate editor text into a <script> tag, trust already-encoded JSON, or inject markup through a tag manager.
6. In multilingual sites, render translated visible values and language URLs. Reuse a global Organization @id only when it is the same legal entity; do not merge different businesses or locations merely because they share an installation.

Evidence gate

For every affected canonical page class:

1. Fetch the final rendered HTML in a clean frontend session and extract every JSON-LD block.
2. Parse without recovery; require object/array roots, https://schema.org context, known current types/properties, stable unique identities, absolute URLs, and no contradictory duplicates.
3. Compare names, questions/answers, prices, ratings, dates, addresses, availability, images, and links with the visible page and its authoritative TYPO3 record.
4. Validate the whole graph with Schema.org Validator. Use Google's Rich Results Test only for currently supported Google feature types; it has no general public automation contract, so keep representative manual evidence rather than claiming an API run that did not happen.
5. Add project tests for each mapping and a rendered-page regression fixture. Run the identical language/page sample after a change. Zero invalid JSON-LD, blocking consumer errors, hidden facts, fake/self-serving ratings, stale time-sensitive data, and unexplained entity conflicts are allowed.

Search Console evidence is post-deployment monitoring and outside the local upgrade run. Do not deploy or request indexing from this skill.

Boundaries

• Use typo3-seo for canonical URLs, hreflang, meta tags, XML sitemaps, and robots rules.
• Use typo3-content-blocks to create or migrate the visible FAQ/product/event/job/recipe model; this skill maps that model to entities.
• Use the general schema skill for non-TYPO3 sites. This skill owns TYPO3 records, Fluid/API integration, DDEV evidence, and the upgrade-graph contract.
