Open Data Portals (CKAN / DCAT)
Register (data.europa.eu dcat-ap harvest network, dataportals.org) with portal-software deployments (ckan). The Kin Score Market layer reads each provider in its market: who it integrates with, how deep those integrations go, and where the market publishes its own structure. Methodology.
Where this market publishes its structure
- data.europa.eu catalogue registry (data.europa.eu/api/hub/search/catalogues + /catalogues/{id}) machine-readable, 213 catalogues (dcat-ap 91, euodp-legacy 64, geospatial 37, ckan 14, udata 2, socrata 1); 16 linked in-market; EU institutions on europa.eu held as a shared host
- DataPortals.org (Open Knowledge Foundation, dataportals.org/api/data.json) machine-readable, 631 portals (223 Government), 100 with a generator; 59 linked in-market
- CKAN instances register (github.com/ckan/ckan-instances config/instances.json) machine-readable, 199 instances, last commit 2019-03-07 (stale, flagged); 45 linked; deployment edges only
- ckan.org/showcase not machine-readable: marketing showcase page, not a register; not read
- SEMIC DCAT-AP implementations / conformance (interoperable-europe.ec.europa.eu) not machine-readable: no register: the 'SEMIC map' link redirects to the collection home; no DCAT-AP certification list published (2026-10-21)
Own = declares at least one integration itself; covered = visible only because an aggregator, standards body, regulator or partner contract names it; distribution-only = listed only on cloud marketplaces it sells through, a channel reported beside, never counted as its own declared integrations; undeclared = nothing we can read, so no number; declares_compatibility = providers with a `compatible` shape vote, report only (kin, 2026-10-13): never counted as own, never in depth or position.
Taxonomy how this market maps onto apis.io
Derived 2026-10-22 from the 110 providers in this market we could resolve in the catalog. The percentage is the share of those providers carrying each one; it describes the market, not the tag or industry. Tag groups have no page of their own yet, so they are listed unlinked.
| Tags | Open Data 95%, Government Data 77%, Data Catalog 65%, DCAT 63%, CKAN 63%, Open Data Portal 31% |
|---|---|
| Tag groups | Open Data 95%, Government 22% |
| Industries | Government & Public Sector 94%, Data & Analytics 70% |
share of resolved cohort carrying it; tags >=0.20 & >=3 members (max 12, junk dropped), tag_groups >=0.20 (cooccurrence, non-cross-cutting; max 8), industries >=0.20 (max 6), areas >=0.10 (max 6; areas are keyword-matched and sparse), capabilities L1 >=0.20 (max 8); derive-market-taxonomy.py
Leaders by position (provisional)
Provisional: grouped by position, depth compared within a position only. Distribution (cloud marketplaces) and iPaaS bridges are counted beside position, never inside it. Unknown-builder listings are left out of position shares and counted here.
undeclared 110 · declares nothing we can read: no number
Generated 2026-10-22 from API Evangelist's own files; nothing on this page is a model's judgement. Provisional and unweighted; not part of the Kin Score composite or agent readiness.
