--------------------------------------

             Summary: Taverna: Open Geospatial Consortium Web Processing Service support
                 Key: COMDEV-122
                 URL: https://issues.apache.org/jira/browse/COMDEV-122
             Project: Community Development
          Issue Type: Bug
         Environment: Java, Maven
            Reporter: Alan R Williams


Project: Apache Taverna (incubating) http://taverna.incubator.apache.org/
Mentor: Stian Soiland-Reyes <stain@apache.org>

Apache Taverna Language - https://github.com/apache/incubator-taverna-language/ - is a set
of Java APIs for managing and converting Taverna workflow definitions.

Several simple demonstrator/example prototypes for a command line tool over these has been
done, e.g. 
https://github.com/apache/incubator-taverna-language/tree/master/taverna-scufl2-examples
https://github.com/apache/incubator-taverna-language/tree/master/taverna-scufl2-wfdesc
https://github.com/stain/ro-combine-archive

but what is needed is a single command line tool that is production ready, and ideally available
as an executable standalone jar (As in the wfdesc example).

This proposed GSOC project is to formalize the command line interface for Taverna Language
so that it can achieve some of the below:

a) In collaboration with dev@taverna and the mentor, define command line options for workflow
conversions and inspection
b) Find and use an appropriate command line parser library
c) --help
d) Basic error handling (e.g. file not found)
e) Batch processing - e.g. recursive conversions
f) Arguments for choosing input and output formats
g) Unit and Integration Tests for the above (ideally through Maven)

The project can be extended by exposing other parts of the API that don't currently have a
command line equivalent, e.g.

h) Workflow validation
i) Workflow statistics (number of processors, links, etc)

Your command line tool would be added to the Apache Taverna Language release, so you would
be a part of the Apache Taverna developer community http://taverna.incubator.apache.org/community/
which will be able to give feedback, testing and guidance for this GSOC project and beyond.
