HotDAML Newsletter Keeping you up to speed on happenings in the world of DAML http://www.daml.org <http://www.daml.org/> _____ Monday, March 4, 2002 - Issue 6 _____ New Stories: DAML Principal Investigators meeting held in St. Petersburg The DAML PI meeting was held February 13 - 15 in St. Petersburg, FL. Murray Burke, the DARPA DAML Program Manager, set the tone for the meeting with an overview of the goals and objectives of the new DARPA Information Exploitation Office (IXO) and the direction for the DAML project during 2002. Each of the research teams presented the results of their efforts in 2001 and their plans for 2002. Several Working Group meetings focused on areas of interest across the research teams such as Services, Tools, and Security. More information is at: http://www.daml.org/meetings/2002/02/pi/agenda.html Semantic Web for Military Users conference The next Semantic Web for Military Users (SWMU) conference is scheduled for March 25 - 27 at the Navy SPAWAR Systems Center in San Diego, CA. This conference is by invitation only and will explore opportunities for the application of DAML technology to military problems. This is a joint conference that also includes the ESG Enabling Experiments team and the Grid Military Users Group. If you are interested in attending please contact Tom Martin <mailto:tmartinrme@prodigy.net> . DAML Experiment to be key activity in 2002 Many of the technologies developed to date under the DAML Program will be brought together to showcase the overall productivity enhancements available through the concept of the Semantic Web. The DAML Experiment will focus on functionality to support the Joint Task Force Commander and his staff in selecting candidate targets that best satisfy specific the goals and objectives for a military operation. The resulting prototype system is being called the Semantic Operational Net Assessment Tool (SONAT). DAML Semantic Search Server enhanced A new GUI and a few more new features have been added to the DAML Semantic Search Server created by Teknowledge's Agent Semantic Communication Service(ASCS) development team. In addition to providing exact matches to queries, the search engine now allows the user to broaden search based on equivalence relations, inversion relations, subclass and subproperty relations. As a result, the scope of the search is much broader than search purely based on text-string matching. The server performance has also been improved via continuous query ordering and most queries can be answered within ten seconds. Since 2002, the content of the server is updated every week. The server is available at http://plucky.teknowledge.com/daml/damlquery.jsp A DAML Mode for XEmacs and GNU Emacs Anyone who has tried to write DAML ontologies in a text editor will recognize that it requires a lot of typing, and that reading and moving around in such files can be tedious. EmacsDAML, developed by BBN Technologies, is a step in the direction of addressing those problems. DAML-EMACS is a "mode" for use with the EMACS text editor, not unlike the modes for C++, Java, LaTeX, LISP and HTML that existed previously. It provides automatic fontification to make the code easier to read, commands to insert new forms to be filled out, and keyboard commands for moving about the file in logical DAML/RDF or XML units. EmacsDAML is available at http://openmap.bbn.com/burstein/daml-emacs/ DAMLator server side translator for Apache UMBC has developed DAMLator as a module for the popular Apache web server which does server side translations of DAML encoded files and caches the results. Current translation targets include Ntriples, Prolog terms, GIF and PNG. The benefits of using DAMLator are threefold. First, the caching mechanism provides efficiency and scaling by avoiding repeated translations of the DAML encoded files. Second, doing the translation on the server side means that client applications can be smaller, simpler and faster since they do not have to parse and translate DAML files. Third, avoiding the complexity of dealing with DAML directly and making the DAML content available in several forms lowers the barrier for developers to experiment with DAML. DAMLator 1.0 is implemented in Perl and uses HP JENA RDF/XML parser, Apache Xerces and AT&T Labs Graphviz. Future versions will include a web interface through which one can administer, configure and monitor a DAMLator installation.

This workshop is designed to foster collaboration between researchers in workflow, database, systems and AI working on problems related to the confluence of Web Services and the Semantic Web.
