+= AlignmentOntology (AO) Im-/Exporter Tool =
+
+Developer: [mailto:endres@dfki.uni-kl.de Björn Endres]
+
+== Description ==
+This tool enables the user to export any PhaseLibs alignment to an RDF file, specifying the alignment within the AO RDFS scheme. In reverse, it is able to wrap such an RDF file in an PhaseLibs alignment implementation.
+
+== Specification ==
+
+The tool's main class is
+ {{{de.dfki.km.phaselib.tools.alignmentOntology.AOJenaAlignment}}}
+
+A Jena-like vocabulary class for the AO is provided by the class
+ {{{de.dfki.km.phaselib.tools.alignmentOntology.AO}}}
+
+== Usage ==
+
+To '''import''' an RDF file to a PhaseLibs alignment, call the static
+ {{{AOJenaAlignment.importAlignment(source, ontologyProvider)}}}
+
+method of the main class. The ''source'' parameter should be the RDF file or a [http://java.sun.com/j2se/1.4.2/docs/api/java/io/InputStream.html InputStream] providing the RDF data. The ''ontologyProvider'' will be used, to get PhaseLibs ontology adapters for the ontologies referenced in the alignment.
+
+In order to '''export''' an arbitrary alignment, the static 
+ {{{AOJenaAlignment.exportAlignment(alignment, uri, sink)}}}
+
+should be called. The ''uri'' parameter must provide a URI for the alignment, since PhaseLibs alignments do not have URIs. The ''sink'' parameter specifies the [http://java.sun.com/j2se/1.4.2/docs/api/java/io/OutputStream.html OutputStream] to write the RDF/XML data to.
+
+''Remark:'' if the alignment provided is an AOJenaAlignment (as produced by the ''importAlignment(source, ontologyProvider)'' method), the ''writeTo(sink)'' method of this alignment implementation is called. This allows the user to keep all AO extensions that are not reflected in the PhaseLibs alignment concept, since the wrapped RDF Jena model is written out.
+
+=== Dependencies ===
+
+Needs the [http://jena.sourceforge.net/index.html Jena Project], version 2.0 or higher.
