Capture and share data-model metadata

[pvgenuchten]

An important, often overlooked, aspect of metadata is metadata about the datamodel itself. For grid files, it provides a description of the bands/dimensions (name, unit of measure, etc), for vector files it provides a description of the attributes.

iso211 standardised this metadata as feature cataloguing and included an option to embed this metadata in iso19115. Similar initiatives exist in mcf and datapackage

Would be nice if pycsw is able to capture this information and return it as part of record-responses.

Storage

An extra field should be added to the database to capture this information, suggestion would be to adopt the pygeometa schema for these elements

OGCAPI - Records

Records does currently not provide a mechanism to return this type of information. An option could be to add a link with rel='schema' to the link section. The group may be interested to adopt feature cataloguing as an extension to records? Relevant here is that the STAC group has identified a band section in their EO metadata model.

ISO19115

ISO allows to embed so19110 information in a iso19115 record. This information should be extracted when ingesting a iso19115 record and reproduced when returning an iso19115 record
