The protégé MESAM plugin is a semi-automatic tool for defining a consistant OWL merged model composed of a generic model, a specific model and mapping between them.

Version Changes in this version
MESAM 1.0 see page for more details


Given two models, a generic model used in a generic system and a specific model provided by a designer, MESAM support the construction of a model that would integrate all the particularities of the specific model and be usable in the generic system. MESAM needs the definition of mappings between elements of both models and a validation process at the structural and semantic level. It relies on the designer who has a very good understanding of his model. He will be responsible for semantic validation while all the structural verifications will be done automatically by the plug-in. The main steps are described below, for more details see papers section:

  1. Specification, by the designer, of the equivalence and specialization mappings between classes of the generic model and the specific model, merging the whole generic model and the mapped classes of the specific model (together with the associated mapping links) in order to obtain a new model.
  2. Automatic computation of additional mappings between classes, the mappings and the linked classes being added in the model being built.
  3. Automatic computation of mappings between elements different from classes, i.e. between attributes and between relations.
  4. Validation by the designer of the deductions made by the plug-in in step 3.

For Protege 3.x, download file and unzip it in the Protege plugins directory. the plug-in needs a rule engine to make inferences, it must be installed separately. At present, only the Jess rule engine is supported. Information on installing Jess is described here.
