Also link an object to a project:

Find objects in a collection or linked to a project:

Code Block

language	sql
title	3h. Select Objects Linked To A Collection or A Project

prefix rels: <http://fedora.info/definitions/v4/rels-ext#>
prefix ex: <http://example.org/>
select ?obj where {
  { ?obj ex:project <http://localhost:8080/rest/objects/proj1> }
  UNION
  { ?obj rels:isMemberOfCollection <http://localhost:8080/rest/objects/col2> }
 }

Expected Results

obj
<http://localhost:8080/rest/objects/obj1>
<http://localhost:8080/rest/objects/obj2>

Count objects instead of listing them:

Code Block

language	sql
title	3i. Count the Objects Linked to a Collection or a Project

prefix rels: <http://fedora.info/definitions/v4/rels-ext#>
prefix ex: <http://example.org/>
select (count(distinct ?obj) as ?count) where {
  { ?obj ex:project <http://localhost:8080/rest/objects/proj1> }
  UNION
  { ?obj rels:isMemberOfCollection <http://localhost:8080/rest/objects/col2> }
}

Expected Results
