It is a brief summary of the longer document [1] which identifies the requirements and objectives for the Web Ontology Working Group. Summarizing what you will find there, the goals of our group are not to reinvent these various features, but to make sure our solution is maximally compatible with existing implementations and/or does not break other standards. In particular, we currently assume we will get arithmetic and string manipulation from the "underlying strata" (i.e. XML and RDF) and thus do not anticipate creating our own solution for these. -Jim Hendler WOWG CoChair [1] http://www.w3.org/TR/webont-req/ -- Prof James Hendler hendler@cs.umd.edu Dept of Computer Science http://www.cs.umd.edu/~hendler AV Williams Bldg 301-405-2696 (work) Univ of Maryland 301-405-6707 (Fax) College Park, MD 20853 USA
