DAG-Edit 1.400-beta-1 is now available. Get your copy at
This is truly a beta release. This version is NOT INTENDED FOR PRODUCTION
WORK. Please download this version only if you are interested in beta-testing
DAG-Edit and the new OBO flat file format.
This version of DAG-Edit contains a completely rebuilt core. All the
datamodels and the undo system have been rebuilt around history items, which
should allow us to do some very interesting things with version checking.
DAG-Edit now incorporates all the concepts developed in the OBO file format
* Support for multiply rooted graphs
* Full support for disconnected/cyclical graphs
* Special storage and treatment of obsolete terms
* Support for annotation of replacement terms to obsolete terms (to do
this, just drag the replacement term onto the obsolete term)
* Teatment of relationship types as terms
* A built in definition of the is_a relationship type from which all other
type definitions derive
* Support for synonym types
and many other changes.
Further, the entire display caching system has been redesigned, which should
allow for much faster selection, editing, and searching.
