Validate one public DCAT-AP catalog metadata document against the official pinned SEMIC DCAT-AP SHACL shapes with exact shape, focus-node, and severity evidence, or compare two same-profile catalogs before and after a harvest, with a clear structural-conformance-versus-metadata-quality boundary.

Data Catalog Check questions
Scope and boundaries for Data Catalog Check.
01What does Data Catalog Check actually check?
Validate one public DCAT-AP catalog metadata document against the official pinned SEMIC DCAT-AP SHACL shapes with exact shape, focus-node, and severity evidence, or compare two same-profile catalogs before and after a harvest, with a clear structural-conformance-versus-metadata-quality boundary.
02What does it never do?
It reports what its pinned engine measured and nothing more — it does not judge quality, correctness of your underlying business decisions, or anything outside its stated scope, and it never fabricates a result.
03What does it cost?
Nothing. Every published app is free to use with fair-use rate limits.
04Can my assistant connect directly?
Yes — any MCP-compatible assistant can connect straight to the canonical endpoint: https://powmcp.com/data-catalog-check/mcp. Marketplace listings are conveniences over the same live engine.
