The Annotation Graph Schema API

This API is derived from the Annotation Graph definition and implementation . It is intended to serve as a backend to XML-based annotation APIs or as middleware to annotations in other formats where the use of XML-based tools is needed for the purposes of querying and creation of annotation bases.

We would like to thank Tom Morton and Jeremy Lacivita for granting us permission to use the annotation.org namespace.

Language and Library Dependence

All implementation and libraries are in the Java™ programming language compiled using Java™ 1.4.2.

Xerces-J libraries are included in the distribution. The APIs are dependant on the version included so as far as possible use them.

Do contact us if you need to discuss the issues of compatibility with different versions of Java™ or Xerces-J.

Building from source

Download as above and then do the following(just press enter when prompted for a password by cvs).

cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/agschema login

cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/agschema co agschema_dev

cd agschema_dev

If the downloaded distribution is in $DIST

cp -R $DIST/lib .

You can now run

ant distNoDocs

You will of course need Ant. If you wish to generate docs as well you will need XSDDoc a version later than 0.5beta if one exists or build from source. Install XSDDoc as required for the ant task. The default ant target should then generate docs as well.
