- 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>
