OpenSearch and INSPIRE ATOM
Warning
Not yet available in version 4.
OpenSearch
The catalog provides an opensearch entry point at http://localhost:8080/geonetwork/srv/eng/portal.opensearch. This service is advertised in the HTML.
Browsers detect the availability of opensearch by checking the index page at the root of the (sub)domain. If you install geonetwork in a subfolder, consider to set up a rewrite rule forwarding the index request to the subfolder.
An example of such a rewrite rule in Apache:
Verify in a browser if opensearch is detected by typing the url and then a space. The url bar should then give an indication that you're searching within the site.
INSPIRE ATOM
The INSPIRE technical guideline for download services facilitates an option to set up a download service based on OpenSearch and Atom. A separate OpenSearch endpoint is created for every Atom-based download service.
Note
Only records based on the ISO19139 standard can be used with Atom. ISO19115-3 records are not.
A remote ATOM feed can be registered in a metadata record (see Linking data using ATOM feeds), but the catalog can also create ATOM feeds from records describing datasets and services.
For a service metadata record, the corresponding ATOM feed is accessed at: http://localhost:8080/geonetwork/srv/atom/describe/service?uuid=8b719ebd-646e-4963-b9e0-16b3c2a6d94e. If the service is attached to one or more datasets (see Linking a dataset with a service), then the feed will also expose each dataset as an entry in the feed. Check that the service type is set to download (if not, the dataset feed will return an exception).
The dataset feed is accessible at: http://localhost:8080/geonetwork/srv/atom/describe/dataset?spatial_dataset_identifier_code=b795de68-726c-4bdf-a62a-a42686aa5b6f. Links will be created for each online resource flagged with a function set to download.
