Modelling Mash-up Resources

Resumen. Web-based applications to assemble web resources, like Yahoo Pipes or Netvibes, are emerging as a basis for a new wave of Internet applications that bring semantic web to the general public. Nevertheless, technologies and conceptual tools that allow ordinary users to combine application functionality are immature. There are some formal models but most of them are ontologies that do not capture the complex semantics behind resource composition and resource functionality. In this work we present a formal semantics, in the form of an ontology, to represent resources, composition of resources and resources in execution. Our semantics offers a framework for building tools that assist users to discover resources and connecting them depending on their functionality and their data types they share.
