- 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> standartd 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>
