+ The <b>MathQL-1 Suite for HELM</b> is implemented in <a
+ href="http://caml.inria.fr/">Caml</a> and is currently available through
+the <a href="http://www.cs.unibo.it/cgi-bin/cvsweb/helm/">HELM CVS repository</a>.
+ The Suite provides the following software components: <br>
+
+ <ol>
+ <li>The basic Caml package for MathQL-1 (<a
+ href="http://www.cs.unibo.it/cgi-bin/cvsweb/helm/ocaml/mathql/">mathql</a>)
+ provides a <a href="http://helm.cs.unibo.it/">HELM</a> independent Caml
+representation of queries and query results, plus some functions to convert
+this representation in text and XML and viceversa.</li>
+
+ </ol>
+
+ <ol start="2">
+ <li>The MathQL-1 interpreter (<a
+ href="http://www.cs.unibo.it/cgi-bin/cvsweb/helm/ocaml/mathql_interpreter/">mathql_interpreter</a>)
+ is HELM dependent just in the implementation of the <i>property</i> operator,
+ which still relies on the architecture of the relational database holding
+ HELM metadata. The HELM team is planning to remove this drawback in the
+near future.</li>
+
+ </ol>
+
+ <ol start="3">
+ <li>The HELM query generator (<a
+ href="http://www.cs.unibo.it/cgi-bin/cvsweb/helm/ocaml/mathql_generator/">mathql_generator</a>)
+ allows to build specific kinds of MathQL-1 queries, which are meaningful
+ in the context of HELM, starting from a high-level description of the wanted
+ results. These queries are descibed at an abstract level in the following
+ paper:</li>
+
+ </ol>
+
+ <blockquote>
+ <ul>
+ <li>F. Guidi and C. Sacerdoti Coen: <i>Querying Distributed
+ Digital Libraries of Mathematics</i>.<br>
+ </li>
+
+ </ul>
+ </blockquote>
+
+ <ol start="4">
+ <li>The testing software for the MathQL-1 Suite (<a
+ href="http://www.cs.unibo.it/cgi-bin/cvsweb/helm/mathql_test/">mathql_test</a>)
+ providides three textual interfaces (one for the basic package, one for
+the interpreter and one for the query generator) with specific features meant
+ for testing.<br>
+ </li>
+
+ </ol>
+ The current version of the Suite, realized entirely by F. Guidi, implements
+ MathQL-1 version 3 (i.e. MathQL-1.3). The newly implemented features, which
+ are not included in the ufficial <a href="documentation.html">documentation</a>
+ yet, are reported in the <a href="whatsnew.html">What's new</a> section.<br>
