cz.cvut.kbss.jsonld.common.IdentifierUtil

public class IdentifierUtil
extends Object

Allows to generate blank nodes for identifier-less instances.

Although objects in JSON-LD are not required to have id, some tools may have issues processing such data. In addition, multiple references to the same instance cannot be created when serializing the JSON-LD, as there is no identifier to reference.
