The new DIG interface standard (DIG 2.0)

DL Implementation Group (DIG)

The DL Implementation Group (DIG) is a self-selecting assembly of researchers and developers associated with implementations of Description Logic systems. Members of DIG have irregular informal get-togethers at DL-related events, such as the annual Description Logics workshops.

DIG Interface

The key contribution of DIG has been the DIG interface. This specifies a common interface for Description Logic Reasoners and allows a variety of tools such as ontology editors to make use of DL reasoners. The interface specification defines a concept language and a minimal set of operations.
