This Java application provides an interface to browse, query and edit GO or any other vocabulary that has a DAG data structure. The most current version of DAG-Edit can be downloaded from the publicly accessible source repository at SourceForge. Help documentation is now included in the program, or is avaliable here.
The GO flatfiles and associated data are incorporated into a MySQL database on a monthly basis.
The GO-DEV toolkit is the collection of scripts, applications and database schema modules above developed by the BDGP. It includes the software above, as well as object oriented libraries in perl and java for handling GO and OBO style ontologies.
All of the software we develop is open source, and is available from the sourceforge site. DAG Edit has frequent releases. For the rest of the software, you should use CVS to obtain the latest version. If CVS is not an option, you can download the latest monthly release of the code from the GO Database Download Area -- please select the file go_YYYYMM-utilities-src.tar.gz.
