Subject [jira] [Commented] (COMDEV-121) Taverna: Databundle viewer for web
Date Mon, 02 Mar 2015 10:45:04 GMT


Ian Dunlop commented on COMDEV-121:

Alan's summary is pretty much spot on. What is needed is a system that allows a user to upload
a databundle for a workflow run (via file or URI) and then allows viewing and navigation of
the steps within the workflow run (and therefore the provenance) and downloading of inputs
and outputs. (I would edit but I don't seem to have the permissions!)

> Taverna Databundle is a file format returned by the Taverna Server containing the results
of a Taverna workflow run and its intermediate values and provenance metadata.
> The databundle is a structured ZIP file with metadata in JSON-LD.
> This GSOC project proposes to create a web-based presentation of a workflow run, e.g.
the following user story:
> 1) User uploads a wfrun  (or provides the URI to one existing elsewhere)
> 2) Server shows basic information about bundle
> 3) User navigates to inputs/outputs
> 4) Server present list of inputs or outputs - embedding images etc. where possible, download
links for large files, inline for small text, etc
> 5) User downloads a selected data file
> Metadata provided can be presented in many different ways, for instance:
> a) Which workflow was executed?
> b) Which steps were executed?
> c) What step produced this value?
> d) What values were produced by this step?
> e) What steps used this value?
> The student is free to choose programming language and web framework, as long as a free
runtime is available (e.g. Ruby on Rails, Java CXF, Node.js, Bootstrap, Ember).
> Your web viewer should aim to be added to the Apache Taverna as a release, so you would
be a part of the Apache Taverna developer community
> which will be able to give feedback, testing and guidance for this GSOC project and beyond.
> We can provide virtual servers for hosting the viewer prototypes.
