I know the reply on this is quite late - I was waiting for the end of the semester to give some real thought to the response, so I hope it doesn't come too late to be of use.

Some information that I think could be useful, besides the type of services, might be:

-Number and type of ports (e.g. text vs 2-deep list of text, etc.)
-Output types - this would be particularly good for finding workflows that produce graphs, e.g. searching for workflows that have an R component and a png output type
-Whether it contains subworkflows (or subsubworkflows)
-Complexity, though there are a number of ways you could operationalize this; basically I'd like to be able to look only at workflows that are not straight linear structures, that make use of the outputs from one component as input to more than one component, etc.
-License - more likely to be useful for search than anything else
-Metadata completeness; I would love to be able to have a checkbox so that I could exclude from search results any workflows that don't have metadata for non-shim components. I've seen this on another social network site, labelled "include all photo-less?" which is inelegant but perfectly descriptive.

That's all I that comes to mind at the moment - hope it's useful!

Cheers,

Andrea

Hello everybody,

The myExperiment, http://www.myexperiment.org , people are considering
adding more information about a workflow based upon its contents.  I
have already suggested to show the types of service (WSDL/BioMoby/ RShell
etc.) in the workflow.

There is a lot of information that could be shown.  What do you think
would help you search for and select/reject appropriate workflows?

At the moment, they want input on the characteristics of the workflow
definition, not information such as its service reliability or
usefulness (although they are obviously interested in showing that type
of information as well).
