- The MathQL proposal rises in the context of the <a
- href="http://helm.cs.unibo.it/">HELM project</a>, which aims at the development
-of a suitable technology for the creation and maintenance of a virtual,
-distributed, hypertextual library of structured mathematical knowledge
-based on <a href="http://www.w3.org/XML/">XML</a> technology, through the
- integration of the current proof assistants and logical frameworks with
-the most recent technologies for the development of Web applications and
-electronic publishing.<br>
- <br>
- The objective of the MathQL proposal is the development
-of a set of query languages enabling the retrieval of formalized mathematical
- Web resources on the basis of content-aware requests. The first of these
- languages, <b>MathQL-1</b>, is focused on querying an arbitrary
- <a href="http://www.w3.org/RDF/">RDF</a> database because RDF is
-the <a href="http://www.w3.org/">W3C</a> standard for describing
- Web resources at the general-purpose content level.<br>
- <br>
- As an RDF query language, MathQL-1 provides the main features
- required by the RDF community while complying with the needs of HELM.
- The peculiar aspects of this language concern the query results,
-which are highly structured and possess their own syntax, formally
-explained by a rigorous semantics.<br>
- <br>
- MathQL-1 is particularly helpful in distributed systems
-where query engines are implemented as stand-alone units, because
-in this situation the query results are exchanged between the system
-components as well as the queries, and thus both the queries and the query
-results need to be encoded in a clearly defined format.<br>
- <br>
- Other languages to be developed in the context of the MathQL proposal
- will be suitable for queries about the semantic structure of mathematical
- data: this will include content-based pattern-matching (MathQL-2) and
-possibly other forms of formal matching involving for instance isomorphism,
-unification and definitions expansion (MathQL-3).<br>
