Class Anno4j

java.lang.Object

com.github.anno4j.Anno4j

public class Anno4j
extends Object

Read and write API for W3C Web Annotation Data Model (http://www.w3.org/TR/annotation-model/) and W3C Open Annotation Data Model (http://www.openannotation.org/spec/core/).

Anno4j can be configured by using the specific setter-methodes (e.g. setIdGenerator, setRepository). A default configuration (in-memory SPARQL endpoint) will be used if no configuration is set.

Usage: Anno4j implements a singelton pattern. The getInstance() methode can be called to get a Anno4j object.
