ODPS

Validate, understand and author ODPS v4.1 descriptors for AIMEAT EXCHANGE listings. Free and local in the browser; the same validator is a metered capability for agents. Bilingual EN/FI.

About this app

ODPS checks, explains and helps you write descriptors in the Open Data Product Specification (ODPS) version 4.1. ODPS is a Linux Foundation project at opendataproducts.org. A descriptor tells a buyer what a data product or service is, what it costs, how to call it and who stands behind it. Each listing on AIMEAT EXCHANGE already has an ODPS 4.1 descriptor, which the node makes from the listing.

The app has four tabs:

Validate. Paste a document in YAML or JSON, fetch it from a URL, or pick a live listing on this node. The app checks it against the official ODPS 4.1 JSON Schema and groups the problems by product element. Press a problem, and the cursor goes to its line.
Elements. Each part of the specification, what a good entry looks like, and live examples from this node.
Why it matters. What a full descriptor changes for a buyer and for a listing.
My listings. Sign in to see your own listings and what each one lacks. The app can make an AI draft of the descriptive fields. Read every line before you use it. The draft is kept in your own memory.

Validation runs in your browser. Nothing that you paste leaves your browser, and you do not need an account for it. The app is in English and Finnish.

Use ODPS when you publish a capability on EXCHANGE and want buyers to see the licence, the provenance and your commitments before a contract.

About this appVersion 2.1.0 (update 12) · updated Oct 24, 2026What changed

2.1.0: a problem in the verdict is a way into the document — pressing it puts the cursor on the line its path points at, in YAML and in JSON. The AI draft of a listing and the document being checked are kept in your own memory, so a reload or another device no longer throws them away; a draft can be discarded. Fixed: Copy found no block once a draft carried its AI label. (12)
2.0.0: on the Atelier track with the same hero, tabs, cards and layout; the validator, schema and explanations unchanged. Fixed: the Finnish text lost its ä and ö in a dozen messages; the standards an AI draft names now go into the odps block (they were drafted and dropped); an AI draft carries the AI label and its provenance; the API follows the node the page is served from. (11)
