I am interested in clarifying the extents.temporal.values field. It is present in the EDR spec for temporal extents, but not in the OAF

[tomkralidis]

OGC API - Features does not imply a temporal model for collections. Feature data may or may not have a temporal aspect.

OGC API - Environmental Data Retrieval implies a more specific collection model given the temporal nature of the data it aims to support.

[webb-ben]

As written, there is no differentiation between the OGC API - EDR and OGC API - Features temporal configuration. Should EDR collections be validated against https://schemas.opengis.net/ogcapi/edr/1.1/openapi/schemas/collections/extent.yaml?

Or is it fine as implemented in this PR?

[tomkralidis]

pygeoapi only validates OpenAPI generation and config (not at runtime). For responses, we create the response as per the specification(s) and leave hard validation to CITE.
