Value dot: ● values fit the format (joinable) · ● partial · ● mismatch · ● no samples. ◆ matched by the source's declared concept (highest confidence) · ≈ matched by pattern (lower confidence) ·* required · a “param” kind is a request input you can call the API with (driving sequential, drill-down queries). “Filterable” is authoritative for Opendatasoft and request parameters, captured for DataFair, inferred for feature services, and unknown for plain OpenAPI response fields.

Joining sources on this key

The concrete recipe: 2 live sources can be queried by a de_ars value directly. Pick a value, run each call, and the responses describe the same entity from each source's angle.
