Open Grid Forum 22 Report (ID - 111) Ian Kelley School of Computer Science, Cardiff University, Cardiff, UK Email: I.R.Kelley@cs.cardiff.ac.uk 14th March 2008 This GridNet2 report gives an overview of my activities at OGF22 in Boston, which took place Feb 25 - 29, 2008. I participated in the following sessions: • WFM-RG: Workow Sharing and Interoperability Session — The general session focused on the need for sharing workflows for scientific applications. There was an interesting discussion on the responses to the questionnaire that was circulated before the session asking for use-cases and practical guidelines for the sharing of workflows. I participated in this discussion and asked some questions regarding the different application groups and the scope in which workflow-sharing was envisioned (between application domains, or solely within, etc). There was a committee developed to take the results of this questionnaire and write them up in an OGF document. • Additional Sessions — I also attended several additional sessions throughout the conference and had the opportunity to meet with GridSphere (and Vine) developer Michael Russell (PSNC) who gave me a demonstration of the new work he is involved in using Adobe Flex (Flash) to enable more interactive portal development (Web 2.0). This was very interesting and I think some of this work can be used within the WHIP project to enable the portal-side sharing of workflows. Flex also seemed to be an potential technology for interactively building and visualizing workflows within a web environment. It was decided that the best meeting for the initial EDGeS BoF would be at OGF23 in Barcelona, as many EDGeS partners would not be attending OGF22 (OGF22 was quite small, with only 240 participants). I expect to be attending OGF23 on non-GridNet2 funds to pursue this aspect of my application.
