Class Authorization

java.lang.Object

org.trellisldp.spi.Authorization

public class Authorization
extends java.lang.Object

This class provides access to data defined in an WebAC Authorization graph. Access to a resource can be controlled via WebAccessControl, an RDF-based access control system. A resource can define an ACL resource via the Link header, using rel=acl. It can also point to an ACL resource using a triple in the resource's own RDF graph via acl:accessControl. Absent an acl:accessControl triple, the parent resource is checked, up to the server's root resource. An ACL resource may contain multiple acl:Authorization sections. In an LDP context, this may be represented with ldp:contains triples. Another common pattern is to refer to the acl:Authorization sections with blank nodes.
