    1. Exploitation of RDF technology + to manage metadata and compliance with the main requirements for +an RDF query language. In particular:

    + +
    +
      +
    • MathQL-1 provides facilities for hierarchical constraints +based on RDF Schema and for +traversal of compound values of properties.
      • + +
    + +
      +
    • MathQL-1 provides a full set of Boolean operators to compose + the query constraints and facilities for selecting URI's or literals by +means of regular expressions.
      • + +
    + +
      +
    • MathQL-1 allows to customize the query results specifying +what part of a solution should be preserved or discarded.
      • + +
    + +
      +
    • MathQL-1 has a well-conceived semantics defined in term of + an abstract metadata model, imposes that queries return exhaustive solutions + and includes a "select-from-where"-like construction.
      • + +
    + +
      +
    • MathQL-1 supports a machine-processable XML syntax as well as a human-readable + textual syntax to achieve the best usability.
      +
      • + +
    +
    + +
      +
    1. Careful treatment of query results that are as important + as the queries themselves. In particular:
