*** IMPORTANT NOTICE ***
The source code of the earliest version of the EARMARK Data Structure is now available at
Even if the SourceForge repository is still active, it concerns old versions of the API and it is not maintained anymore.
*** SERVICE DESCRIPTION ***
Extremely Annotational RDF Markup (EARMARK) is an ontological approach to the specification of markup structures on text content. It allows not only documents with single hierarchies (as with XML) but also multiple overlapping hierarchies.
- Create markup document with complex and overlapping hierarchies
- Based on well-known Semantic Web specification, such as RDF, OWL and SWRL
- Store and load additional semantic assertions into EARMARK documents
- Verify document properties through Semantic Web technologies
