discover the link from wfs:getcapabilities to metadata-link-content

[pvgenuchten]

A wfs-getcapabilities document typically has a number of links to metadata content. If a crawler accesses a new getcapabilities document, via the WFS-proxy, it will discover metadata via those links, which may or may not already be available in a coupled catalogue (if available). A process should be able to grab that metadata and make it crawlable for the search engine (convert to schema.org).

Two approaches:

• a CSW proxy may instantly convert the iso19139 document to schema.org and expose it to the crawler with a urn of http://{csw-proxy}?url={full-csw-request-as-get}
• A process will verify if the CSW document is in the coupled catalogue, and if so expose that document to the crawler using a urn http://{catalogue}/dataset/{namespace}/{uuid}, if the catalogue doesn't contain the document, the process will trigger a harvest of that document into the catalogue (how will the catalogue later synchronise that resource)
