Re: [Myexperiment-discuss] Are web services provided?

[David R Newman]

Hi Fki,

Speaking from the perspective of Taverna workflows [1], which make up a
large number of the workflows hosted on myExperiment; each workflow has
a number of processors through which data flows.  The function of these
processors may be encoded into the workflow itself but often these
processors call out to a web service and await a response.  As these web
services are completely separate to the workflow (and probably provided
by someone who has nothing to do with Taverna) there is no guarantee
they will respond.  However, I believe Taverna provides libraries of
suggested web services but you would have to ask some involved more
directly with Taverna how / if these libraries are maintained.

a lot of work has gone into monitoring workflows to ensure they are
still functioning (correctly) [2].  If you are building a workflow that
needs to be reliable into the future, you obviously need to ensure the
web services you choose are reliable.  This is why our sister project
BioCatalogue [3] was set up to catalogue bioinformatic and other
biological web services to help users find web services that are both
appropriate and reliable.
