    • requirements:
      • semantic (in addition to structural) annotation of:
        • services (actor) and
        • datasets
      • for ... discovery, WF design, ...
      • prerequisites: what does this annotation langauge have?
    • structural types

      • e.g., relational schema type, ptolemy type
      • applies both to data and "functions" (actors)
      • essentially, useful for plumbing -- the level of the programmer, or data provider
    • semantic type
      • formal expression referencing concepts in an ontology
      • to provide a high-level, conceptual of data and services
    • data(set)
      • informal descriptions: eml style metadata, keywords, controlled vocabularly
      • formal description
        • dataset ~ concept
        • attribute (column) ~ concept
        • fine-grained:
          • query(X1, X2, ..., Xn) ~ concept expression(X1, ..., Xn)
          • Xi are "tags" or variables point to substructure
