This page provides detailed steps for creating repository content via the REST API, and SPARQL queries to demonstrate that content in the triplestore. Much more information about the REST API is available at: REST API and Another Take on the REST API.
Finding Objects by Datastream Name or MIME Type
- Create a few sample objects with either a PDF or a text file, or both attached as datastreams:
curl -X POST http://localhost:8080/rest/objects/101?mixin=fedora:object curl -X POST -H "Content-type: application/pdf" --data-binary @test.pdf \ http://localhost:8080/rest/objects/101/master/fcr:content curl -X POST http://localhost:8080/rest/objects/102?mixin=fedora:object curl -X POST -H "Content-type: text/plain" --data-binary @test.txt \ http://localhost:8080/rest/objects/102/master/fcr:content curl -X POST http://localhost:8080/rest/objects/103?mixin=fedora:object curl -X POST -H "Content-type: application/pdf" --data-binary @test.pdf \ http://localhost:8080/rest/objects/103/master/fcr:content curl -X POST -H "Content-type: text/plain" --data-binary @test.txt \ http://localhost:8080/rest/objects/103/text/fcr:content
- Find objects with a datastream named "text":
prefix fcrepo: <http://fedora.info/definitions/v4/repository#>
select ?object where { ?ds fcrepo:mixinTypes "fedora:datastream" .
?ds fcrepo:hasParent ?object . filter(str(?ds)=str(?object)+'/text') }
- Find objects with a PDF datastream:
prefix fcrepo: <http://fedora.info/definitions/v4/repository#>
select ?object where { ?ds fcrepo:mixinTypes "fedora:datastream" .
?ds fcrepo:hasParent ?object . ?ds fcrepo:hasContent ?content .
?content fcrepo:mimeType "application/pdf" }
