Description

If Taverna workflows are to be represented in CWL, then the problem is that our activity descriptions are only usable within Taverna. (Except the Tool Activity which could be represented as a ShellCommandRequirement).

A quick-and-dirty CWL representation of any Taverna workflow would need a TavernaActivityRequirement - but obviously only Taverna could read those back in.

So a better approach could be to have a Docker image (in CWL using a DockerRequirement) that executes a Taverna Activity as an independent step - that would mean Taverna activities like WSDL and REST activities can be used in CWL.

One way to do this today is for a Docker image that generate a simple SCUFL2 workflow that executes just that single activity, and then just runs Taverna's executeworkflow.

Taverna's CWL reader could then recognize these and re-instate the Taverna activity (as this Docker tool can keep the existing Taverna Activity JSON as its own configuration).
