Hi, We are a group of bioinformaticians at the Institute for Plant Biochemistry in Halle/Germany.
We have created a small set of Mass Spectrometry and Metabolomics related BioMoby services and Workflows, some of the early ones can be found at http://www.myexperiment.org/users/937/workflows However, we don't dare to teach our Biologists next door how to use the Taverna workbench, because simply for execution of workflows it is a bit overkill. Hence we started creating a Web based "player" for pre-canned workflows. A technical pre-preview is available at http://msbi.ipb-halle.de/MetFlow/. This one tries to obtain information on a metabolite measured as Tandem-MS peak list. At the top-left you find the main input field, in out case a peak list, and some additional (secondary in BioMoby speak) parameters a bit further down. Just hit the "Run Workflow" button, and see our servers go up in smoke ;-). Honestly, there was no stress tests and no layout optimisation efforts so far. This workflow incorporates some external webservices, so if something is going wrong there, you will experience a timeout after five minutes. Once finished, three lists for the outputs of the workflow will appear, which carry further information from Pubchem, www.chemspider.com or the KEGG pathways. The larg-ish text field and graphics open in separate windows. We'd be interested in putting the code up, so that others can join the development of this as a platform, possibly integrated into the Taverna project next to the Workbench. I can envision two use cases for this platform: 1) As a "cheap" web based enactor, no local software needed, and the interface is automagically created from the description. This is what we currently have in place. 2) As a "JSF tag library". A tag library in JSF world is a set of related visual (and invisible) components you could think of Buttons, Tree-views or Calendars in "normal" web applications and for Taverna workflow outputs renderers such as DNA-prettyprinters, ZoomablePathwayViewers, MoleculeVievers etc. This allows to hand-craft (sets of) web pages using these components to create rich web applications with (one or more) Taverna workflows used for the Business Logic (or Bio Logic ;-) Technically we use Tom Oins platform code, and call that from JavaServerFaces (JSF) pages on a Tomcat server. The interface is done using the JBoss RichFaces JSF library, which has some cool Ajax features included. Are there any comparable efforts out there ? Anybody interested in joining in ?
