Class LdpConstraintService

java.lang.Object

org.trellisldp.constraint.LdpConstraintService

All Implemented Interfaces:

ConstraintService

@ApplicationScoped
public class LdpConstraintService
extends Object
implements ConstraintService

A set of constraints applied to user-provided graphs.

This class includes the following restrictions on a provided Graph:

• Prevent LDP types to be set explicitly (Link headers should be used).
• Direct Containers require certain defined predicates (as defined by LDP).
• Indirect Containers require certain defined predicates (as defined by LDP).
• ldp:contains triples may not be set directly (as defined by LDP).
• ldp:contains may not be used as a membership property.
• rdf:type may not be used as a membership property.
• any rdf:type Triple requires an IRI as object.
• any ldp:inbox Triple requires an IRI as object.
• any oa:annotationService Triple requires an IRI as object.
