Link-Up (or sisters) project

myGrid has been awarded one of only 6 projects that link UK e-science activity with related projects in the USA.

LinkUp project Web site http://www.mygrid.org.uk/linkup (URL June 2004)

The current list of actions from the interoperability fest Oct 2004 can viewed under the LinkUpActions topic.

Note that this wiki page is essentially work in progress, the web site has more general documentation and links.

• Actions arising viewed under the LinkUpActions topic.

There was a proposal at GGF in Hawaii on doing the interoperability fest using simple workflows made of shims (a nice name for adapter kinds of components). We could compare and contrast how different tools and techniques address different aspects of workflow development and management. Two important topics for the fest will be representation and tool functionality. [Carole Goble email 6 July 2004]

For a brief description of a shim see the presentation Exploring Williams-Beuren Syndrome using myGrid by Hannah Tipney at ISMB 2004.

NeSC workshop May 2004

The SEEK project ran a eScience GRID Environments workshop at NeSC, Wed 12th to Fri 14th May.

The workshop material is now available on the NeSC web pages for the event.

The agenda:

• Wed 12th 2 parallel sessions
  • Taxonomic Concept Standard, Co-Chairs Jessie Kennedy (SEEK) and Frank Bisby (Biodiversity World)
  • Scientific Workflows (Cramond Room), Co-Chairs Matt Jones (SEEK) and Yike Guo (Discovery Net)
• Thur 13th
  • AM Introduction to OGSA DAI Tutorial - (Neil Chue Hong, Univ. of Edinburgh)
  • PM myGrid Tutorial ( notes NeSCmyGridTutorial )
• Fri 14th 2 parallel sessions
  • Semantic data integration, Co-Chairs Bertram Ludaescher (SEEK) and Chris Wroe (myGrid)
  • Grid Technologies, Co-Chairs Arcot Rajasekar (SEEK) and Paul Watson (North East eScience Centre)

Bertram and Carole have agreed that the semantic data integration session on Friday will effectively be a LinkUp meeting, and obviously the tutorial is an opportunity for SEEK to learn about myGrid. see NeSC-invite.txt: (Bertram's invite)

There are some more details about the meeting on the SEEK wiki, under the EdinburghMeeting topic.

NeSC May meeting report

GGF10 Berlin March 2004

A LinkUp project planning meeting was held in Berlin before GGF10.

The GGF10 workflow workshop includes presentations from Tom Oinn and Bertram Ludaescher.

NeSC workflow workshop Dec 2003

All the LinkUp "sisters" were represented at the NeSC workflow workshop, December 3-5 2003. Talks, available here, included:

• Bertram Ludäscher: Scientific Workflows Based on Dataflow Process Networks
• Chad Berkley: Kepler: A Workflow Tool for Heterogeneous Ecological Data Analysis
• Ewa Deelman: Pegasus: Planning for Execution Grids
• Matthew Addis: Providing Web Service Coordination to Bioinformaticians

Bertram and Carole chaired two discussions on the Requirements of Scientific Workflows. Two outcomes are the rapporteur powerpoint slides ScientificWorkflowRequirementsfinal.ppt summary and a contribution to the workshop final report scientificrequirementsofworkflowbreakoutreport.doc.

NeSC data provenance and annotation workshop Dec 2003

Some of the LinkUp "sisters" were represented at the NeSC data provenance and annotation workshop 1-3 December 2003. Talks, available here, included:

• Dr Luc Moreau: Provenance: Problem, Architectural issues, Towards Trust
• Prof Carole Goble: Knowledge and Provenance: A knowledge model perspective
