Agraphs: Definition, implementation and tools

David Déharbe, Anamaria Martins Moreira, Demóstenes Sena


Agraphs are a graph-based language representation, transformation
and exchange format. In the same vein as XML, Agraphs form a
general data representation mechanism that needs to be instantiated
in different specific applications. In this paper, we present the
Agraphs data structure, programming interface and related tools,
identify their main features with respect to exchange format
characteristics, and compare them to other existing exchange
formats. These different features are illustrated on an instance of
Agraphs for modular Petri nets.
