DCAT US 3 Technical Implementation FAQ

this page is draft and should be filled in soon

DCAT-US 3.0

Is the DCAT-US 3.0 harvester stable enough to test against, or should we wait for production?

Core DCAT-US 3.0 support in the harvester has landed and has no open known defects as of this writing. We appreciate agencies testing against it, and it's likely we'll need to make some fixes as this is new. Testing against a test harvest source is reasonable, and the ingested output should be a fair preview of production behavior.

A couple of caveats before relying on it for anything final:

• Guidance on some edge cases is still being finalized, including how to represent theme: geospatial and how to link ISO/CSDGM records as distributions.
• A standardized "dev/test report" process, so agencies can get a clear before-you-go-live confirmation, is still in development. Until it's ready, the harvest source's own validation output is the best signal available.

Bring any edge cases you hit to DCAT Interagency Q&A Office Hours.
