The Open Data module publishes a governed selection of your catalog as structured, public product data: schema.org JSON-LD, versioned feeds and a read-only endpoint. You decide what is public. Everything else stays behind the gate.

Buyers increasingly start with a search engine, a marketplace or an AI assistant. Those systems don't read your PDF data sheet — they read structured data. If your own, authoritative data isn't available in a form they can use, they rely on whatever copies they find elsewhere.
Assistants and AI search summarise products from structured, openly accessible sources. Clean attributes, units and identifiers make it more likely that answers reflect your current specifications — not an outdated reseller copy.
schema.org Product markup is the established vocabulary search engines use to understand product pages. Consistent JSON-LD on your own site describes each product unambiguously.
They need complete, current data in their format, on their schedule. A versioned feed replaces one-off exports sent by email.
Partner systems, planning tools and specification platforms need reliable technical data they can pull on demand — without an account request for every download.
PIM GATE DOES NOT GUARANTEE RANKINGS OR INCLUSION IN THIRD-PARTY SERVICES. IT MAKES YOUR DATA AVAILABLE IN THE FORMATS THEY READ.
An AI assistant quotes a measuring range we changed two years ago — from a reseller's copy of our data.
02 · How it works
Open Data is not a second export. It is a published view of the same validated data your portals and APIs already use — filtered by rules you set.
Illustrative figures based on the fictional MESSARA demo catalog.
Define which products, attributes and languages are public — by category, market, lifecycle status or flag.
Only records that pass your quality rules for the Open Data profile are published. Incomplete records are held, not exposed.
PIM Gate generates JSON-LD, feeds and the public endpoint from the selection and versions every release.
Changes in your PIM flow through the gate; affected records, feeds and change logs update on the next publication run.
Nothing becomes public because it exists in your PIM. A record is published only when it matches your selection rules and passes validation. Prices, stock, customer agreements and internal attributes stay behind the gate — visible only to entitled users in your portals and APIs.

04 · Outputs
Every output is generated from the same selection and carries the same version number, so a feed, an API response and your website markup never disagree.
| Output | What you get | Typical consumer | Status |
|---|---|---|---|
| schema.org/Product JSON-LD | One JSON-LD document per product, embeddable in your own product pages (script tag or server-side include) | Search engines, AI assistants | 2026 |
| Versioned feeds | Full and delta feeds in JSON, CSV and XML; every release numbered and retained | Marketplaces, comparison portals, wholesalers | 2026 |
| Public read-only API | GET endpoints for products, categories and feeds; no write access; caching and rate limits | Partner systems, apps, AI agents | 2026 |
| Product data sitemap | Machine-readable index of all public product URLs and their last modification date | Search engines, crawlers | 2026 |
| GS1 Digital Link compatibility | Product URIs in GS1 Digital Link syntax (/01/{GTIN}) that resolve to your public record | Scanners, retail systems, DPP | PLANNED |
| AI-agent index | A manifest in the style of llms.txt that points agents to your datasets, endpoints and licence | AI agents and assistants | PLANNED |
05 · Sample payload
Standard schema.org vocabulary, units as UN/CEFACT codes, stable identifiers. The same record can be embedded in your product page or retrieved from the endpoint.

Every feed carries a version, a publication date and a change summary.
Each dataset carries a licence field you set — an open licence such as CC BY 4.0, or your own terms of use. Consumers see what they may do with the data and whom to credit. Every publication run writes a change log: which records were added, changed or withdrawn, and when.

Public responses are cached and invalidated when a new version is published, so crawlers and partners don't hit your source systems.
The public endpoint accepts GET only. Rate limits protect the service; partners who need more can receive a token for the entitled API.
Serve Open Data from a subdomain such as data.yourbrand.com with its own certificate — part of the tenant's custom domain setup.
