Architecture: fully web-based

a rough sketch of the architecture
  • The XML Schema is externally annotated in RDF
    • Metadata are also stored in the system objects.
    • RDF description can be imported in the system.
    • The system can export RDF annotation
    • A component allows to add metadata to the system objects
  • The user can browse the structure and formulate the query
  • For each element/attribute the system knows and can show to the user:
    • semantics
    • constraints
  • The query is prepared in a general format, can be mapped onto different search engines
