Minutes of Semantic Grid Research Group from GGF 7 |
The Semantic Grid Research Group met twice during the GGF 7 meeting. Session 1 was on Wednesday, Mar. 5, from noon to 1:30 pm. Session 2 was on Thursday, Mar. 6, from 2:00 pm to 3:30 pm. Most of these Sessions were devoted to talks by a number of individuals with experience, interests, or concerns regarding the Semantic Grid. These talks are briefly summarized later in these minutes. PowerPoint presentations for most of these talks are available at the Semantic Grid Research Group's community portal at . Interested individuals are invited to join the mailing list at sem-grd@gridforum.org.
There were two items of new business.
First, the Semantic Grid Research Group noted the desire to create a Scheduling Ontology WG to be co-chaired by Wolfgang Ziegler and Phillipp Wieder with close relations to the Semantic Grid RG. This new WG is expecting approval following GGF7 and should have its next meeting at GGF9, where it would hope to have the first draft of a structure of a scheduling ontology. The new WG would appreciate help in finding if such ontologies already exist, or if existing ontologies or ontology tools could help create a Grid scheduling ontology.
Second, there is intent to create a "Semantic Grid Primer". David De Roure, chair of the Semantic Grid RG, is expecting to start organizing work on this Primer in the coming months, and will be soliciting volunteers. The Primer is expected to be one of the first documents produced by the Semantic Grid RG.
As a start to the Semantic Grid Research Group's discussions, there was an Introduction and Update of work on items of interest to the RG, including a new journal and various W3C activities on the Semantic Web. After noting the IP policy clearly at the start of the first session, Dave reviewed the Charter of the RG, which is particularly directed toward
The RG has six basic tasks:
Carole then noted that Elsevier has created a Journal of Web Semantics, which is soliciting papers on Semantic Grid and Peer-to-Peer Technologies. She also noted that the 1st Workshop in Peer-to-Peer and Grid Computing will be held at the 12th WWW Conference in Budapest in May. This workshop has been organized in cooperation with the Research Group. Deadline for submissions to this workshop is 1 April. WWW2003 will also have a track on e-Services and the Semantic Web. Finally, there will be an International Semantic Web Conference, ISWC2003, in mid-October, 2003, with a mid-April deadline for submissions.
The first session, chaired by Dave, then included the following presentations:
David De Roure - Update on W3C Activities,
notably OWL
Reagan Moore - Relationships and The Grid (a Digital Library Perspective),
with a theme that Grids need to go beyond management of semantic relationships to management of semantic/logical, structural/spatial, and temporal/procedural relationships, and that perhaps we might aim at producing an ontological Grid, not just a semantic Grid
Carole Goble - Describing and Finding Services using DAML + OIL Ontologies,
in which Carole described her work on the myGrid project (http://www.mygrid.org.uk), a 2nd generation open service-based Grid project that serves as a testbed for OGSI, OGSA, and OGSA-DAI. The talk focused on the registration and semantic discovery of services using the DAML+OIL web ontology language.
The second session, led by Carole, included the following presentations after a clear presentation of the IP Policy notice:
Simon Cox - Semantic Support for Grid-Enabled Design Search in Engineering,
which presented an interesting example of how ontology-based reasoning could provide useful and intelligent guidance for making effective use of Grid Enabled Optimization and Design Search for Engineering (GEODISE). In an overly simplistic summary, the ontology provides a way of creating a user manual that adapts to the context of the user and assists in ensuring that the user doesn't forget key steps in work with this tool.
Carl Kesselman - The Semantic Grid: An Infrastructure Perspective,
in which he wanted to increase the likelihood that Ontologies would be incorporated into the Grid infrastructure, not just be added to applications.
Michael Niemi - I3C Registry Group
(I3C is a consortium in life sciences that promotes and guides development of Interoperable software frameworks and solutions in life sciences), with a current mission of discovering and binding them to services in their registry.
Geoffrey Fox - Geospatial Ontologies for Workflow, as well as future activities Crisis Grid/ServoGrid,
noting the Open GIS Web Services (http://www.opengis.org), as well as the difficulties of coordinating organizational management of data needed to respond to emergencies in multi-jurisdictional situations.
John Brooke - Unicore meets Globus Scheduling Using Ontologies,
in which John discussed experience in moving from an "Ancestral Broker" to an Interoperable one.
