Here, queries are formulated in searches. Here, queries are formulated in terms of two ontologies: (1) the legal terms of two ontologies: (1) the legal document ontology which describes the document ontology which describes the properties of the legal documents, (2) a properties of the legal documents, (2) a geographic hierarchy of local geographic hierarchy of local administration offices (i.e. the Spanish local administration offices (i.e. the Spanish local administration offices)administration offices)

ConclusionsConclusionsWe have presented the Semantic P2P Egoster, even

though this application is at initial state, it has well defined goals as supporting semantic applications to retrieve legal documents and on delivering services from the public administration (within the government) to citizens.

The e-Gov domain does still have many needs: knowledge, for instance, has not been modeled at all. These needs represent real challenges for researchers.

We will be focus on further enhancement and evaluation of the Egoster; we will be centered on the reasoning capabilities; we will continue integrating the law and regulation knowledge captured on the EGO Ontology Model and we will compare the model with other ontology models.
