RE: [Myexperiment-discuss] metadata about workflows

[David De Roure]

Hi Alan

myExperiment will carry the metadata that people need, and support the 
standards that people need.  It has an internal data model which we populate 
using available metadata (from the workflow itself, from the gui, from the API) 
and from which we can export in various standards.

For our repositories integration work we use OAI, which in turns uses Dublin 
Core.  Think of this as a sort of library catalogue for workflows! So yes, 
leveraging Dublin Core for T2 metadata makes sense. Packs are exported in 
OAI-ORE, which is an RDF representation.

myExperiment also carries metadata for credits, attribution, workflow 
provenance etc, and it would be useful to discuss which of these could be 
carried in t2flows - what appears "inside" a workflow itself and what is part 
of the myExperiment entry that encapsulates it.

The underlying myExperiment data model is document on the Wiki - for example, 
see http://wiki.myexperiment.org/index.php/Developer:Entities

We also map everything (including the user and social network data model) to 
the myExperiment ontology, which builds on various standards including FOAF and 
SIOC.  I'll let David Newman respond with some more info about that.

What sort of format will t2flows be in (will it be RDF for example?)  It would 
be handy to leverage existing standards and tooling as much as possible.

Thanks

-- Dave

Subject: [Myexperiment-discuss] metadata about workflows

Hello,

Marco Roos has asked (in regards to Taverna 2) about the metadata for
Taverna workflows, especially if it can be related to something like
Dublin Core attributes.

Is there any document/recommendation on what data can be associated with
workflows and then used by myExperiment?

Is the myExperiment data mapped to a standard?

Alan (who is hoping to leverage what you have done)
