Hi, apologies for replying late. That is the correct link for the Taverna workshop invitation - or http://taverna2014.eventbrite.co.uk/ for short.
We have been testing the use of Google+ Hangouts, so we'll try to use that, with recording/streaming to Youtube. That could eliviate some of the timezone issues for anyone who want to join. The Apache Incubator item is the first point on the agenda, we start at 2014-10-30 10:00 GMT - which next week will be outside daylight saving (remember US is still in "summer" time a for a few more weeks to keep Idaho potato farmers happy) Provenance exchange - I am thinking in particular if it would be possible to combine our W3C PROV-O provenance support - https://github.com/taverna/taverna-prov (which describes a workflow run) - with exposing service-level provenance. It is more of a high-thinking research/collaboration idea, not something that is specifically needed. Ideally something like Apache CXF could have a @Provenance method that would expose a related provenance resource via PROV Links headers - http://www.w3.org/TR/prov-links/ - and then Taverna workflows using such a REST service would automatically pick up that provenance resource and embed/integrate it into the resulting Workflow Bundle - with a glue record for the different resource identifiers so that it relates with the rest of the workflow provenance. Thus one can avoid the 'black box' problem of workflow provenance - or at least reduce its impact - as the service can provide more specific provenance as to what it has been doing with its inputs and outputs. The second half would be where that provenance information would go afterwards for further exploration.. I must admit that is still a bit of an open question in the provenance community, beyond "You query it" or "Make a connected-graph-diagram" (which falls over with >10 steps). So I am not sure why CouchDB came into my mind - something for exploring and describing data dependencies would be better suited.
