Dimensions data provides ability to retrieve related entities, such as supporting grants to publications. The list of
all available links is provided here:
Following diagram shows availability of ID fields that can be used to retrieve related source entities.
User can retrieve related entities using two steps. First, retrieve the related IDs, such as for example, retrieving
supporting grant IDs for publication:
search publications where id = "pub.1103155411"
Then, make a follow up request, using retrieved supporting_grant_ids, to request the actual grant information:
search grants where id in ["grant.7025938", "grant.2686578", "grant.2683072", "grant.2491045"]
Similarly, other sources can be linked together, using provided ID fields.
Some entities are only linked in one direction, such as policy documents and publications, so getting publications
linked to policy documents is fairly trivial:
search policy_documents where id="policy.88709"
However, querying policy documents linked to a publication must also be performed on policy documents entity:
search policy_documents where publication_ids = "pub.1053432045"
