Linking to a remote record¶

Adding the link¶

While encoding a relation (ie. parent, source, feature catalogue, sibling, dataset, service), user has the possibility to point to a page describing the remote record.

Remote record can be linked to record in this catalog by pointing to an URL of the remote record. If the remote record is in a GeoNetwork catalog, the landing page of the record is recommended (eg. https://catalog/geonetwork/srv/api/records/{uuid}) - which returns XML if the Accept header is set to application/xml. For GeoNode, the HTML page can work but the UUID will not be identified. The title will be the HTML title of the page. For others, XML document can be used (eg. API call or CSW GetRecordById request).

For sibling, which allows to add multiple links in one call, the panel is modified to list links in a table mode.

Once added, the remote records are identified by a specific icon:

Same icon is used in view mode:

XML Encoding¶

Old implementation encodes link to other record as

uuidref

<gmd:source uuidref="704c6337-aaad-47a9-b300-08f28c0e48e9"/>

or gco:CharacterString

<gmd:parentIdentifier><gco:CharacterString>704c6337-aaad-47a9-b300-08f28c0e48e9<...

or using attributes uuidref, xlink:href like for service/dataset links.

When linking to a remote record, the editor tries to collect information about the remote record:

title
UUID

Currently is supported:

ISO19139
ISO19119
ISO19110
ISO19115-3
GeoNode HTML format

At some point, it may be relevant to also support schema.org tags in HTML page or JSON+LD. Once remote record properties extracted, the link will be added as usual (same processes but with 2 extras optional parameters) with the following:

<gmd:source uuidref="fff43204-793a-4a44-96f7-918672a2047d"
            xlink:href="https://sdi.eea.europa.eu/catalogue/srv/api/records/fff43204-793a-4a44-96f7-918672a2047d"
            xlink:title="Bycatch by bottom touching mobile gears, Jan. 2020"/>
