This pragmatic approach is strongly centered in the use of domain-specific multidimensional ontologies. Inspired by applications needs and founded on ontologies, workflows, and activity models, POESIA provides well-defined operations (aggregation, specialization, and instantiation) to support the composition of Web services. POESIA complements current proposals forWeb services definition and composition by providing a higher degree of abstraction with verifiable consistency properties. We illustrate the POESIA approach using a concrete application scenario in agroenvironmental planning  aAgriculture  aAgricultura  aCoffea arabica  aData integration  aIntegração de dados  aOntologia  aOntology  aSemantic web  aSemânticas de dados e processos  aSemantics of data and processes  aWeb semântica1 aLIU, L.1 aPU, C.1 aASSAD, E.
