I'm just starting to use Taverna for bioinformatics and I think it looks very promising. I attended a recent UK MyGrid users day in Manchester (UK) and saw some impressive applications making use of this technology: http://www.mygrid.org.uk We've used Taverna at the Rowett Institute to make federated queries of two BioMart's of microarray data, then normalised them using an 'R' program as a remote web service by wrapping it with SoapLab: http://www.nesc.ac.uk/events/ahm2003/AHMCD/pdf/115.pdf This was part of a 'proof of principle' demonstrator project for NuGO: http://www.nugo.org It was more complicated to do this than I thought it would be, but well worth the effort of learning how to in the end :-) I've also looked at the 'Galaxia' PHP workflow engine in TikiWiki: http://tikiwiki.org/tiki-index.php?page=GalaxiaWorkflow This is a general purpose workflow engine, though, not specifically for bioinformatics. However, it might be useful for 'server-side' PHP work.
