Subject [jira] [Updated] (TAVERNA-900) Add Common Workflow Language support to Taverna

    Description: 
h2. GSOC: Add CWL support to Taverna

The proposed GSOC task is to add support for  [Common Workflow Language|http://commonwl.org/]
 (CWL) in [Apache Taverna|http://taverna.incubator.apache.org/] (incubating). 

The Apache Taverna community believe CWL support can be added to Taverna in a progressive
fashion, and therefore the GSOC student can achieve success in multiple ways - and depending
on her/his interests and existing skills can choose to pursue *one or two of these tasks*
in detail, and if time permits can "top up" by exploring some of the remaining tasks more
briefly as prototypes.
 
See the underlying [Jira issues|https://issues.apache.org/jira/issues/?jql=project%20%3D%20TAVERNA%20AND%20labels%20%3D%20cwl]
for further ideas.

* Save Taverna workflows as CWL (TAVERNA-881) - basically generate YAML by inspecting workflows
using the Taverna Language API and follow the [CWL specifications|https://w3id.org/cwl/].
* Read CWL workflows (TAVERNA-877) - Add a plugin to [Taverna Language API|https://github.com/apache/incubator-taverna-language/]
to parse CWL's YAML
* Execute CWL tool descriptions (TAVERNA-878) - modify Taverna's [Tool activity|https://github.com/apache/incubator-taverna-common-activities/tree/master/taverna-external-tool-activity]
* Browse and use CWL tool descriptions from the workbench (TAVERNA-880) - modify GUI plugin
to select from a collection or registry of tool descriptions
* Create a Docker tool for executing Taverna activities (TAVERNA-879) - this allows any Taverna
steps to be used by other CWL engines

Other Taverna or CWL-related tasks can of course also be proposed by the students.


h2. CWL

The [Common Workflow Language|http://commonwl.org/] (CWL) is a pragmatic approach to a standardized
workflow language for executing  command line tools on the cloud and on local servers.  

CWL is a *YAML*-based dataflow format, describing how command line tools can be wired together
in a pipeline. An example workflow: https://github.com/common-workflow-language/workflows/blob/master/workflows/FestivalDemo/filtercount.cwl.yaml

CWL has a [vibrant community|https://gitter.im/common-workflow-language/common-workflow-language]
and multiple implementations, including _Rabix_, _Galaxy_ and a Python-based reference implementation
_cwltool_.

h2. Taverna

[Apache Taverna|http://taverna.incubator.apache.org/] (incubating) is a Java-based workflow
system with a graphical design interface. Taverna workflows can combine many different service
types, including REST and WSDL services, command line tools, scripts (e.g. BeanShell, R) and
custom plugins (e.g. BioMart).

Taverna workflows can be executed on the desktop, on the command line, or on a Taverna server
installation, which can be controlled from a web portal, a mobile app, or integrated into
third-party applications.

Taverna is used in a [wide range of sciences|http://taverna.incubator.apache.org/introduction/taverna-in-use/]
for data analysis and processing, including bioinformatics, cheminformatics, biodiversity
and musicology. Workflow engine features include provenance tracking, implicit parallelism/iterations,
retry/failover and looping. 

Taverna workflows are commonly shared on [myExperiment|http://www.myexperiment.org], and can
either be created graphically in the [Taverna workbench|http://taverna.incubator.apache.org/download/workbench/],
programmatically using the [Taverna Language API|http://taverna.incubator.apache.org/download/language/]
or by generating workflow definitions in the [SCUFL2|http://taverna.incubator.apache.org/documentation/scufl2/]
 format.


h2. Community engagement

Interested GSOC students are requested to engage early with the [dev@taverna|http://taverna.incubator.apache.org/community/lists#devtaverna]
mailing list to describe their ideas for approaching this project, to clarify the tasks and
for any questions and issues.

As a first step, the prospective applicant should leave a comment on this Jira issue to indicate
their interest, and the GSOC mentors would be happy to assist on any questions. 

As the project starts we are expecting the student to become part of the dev@taverna community
to regularly discuss their progress. 

We are also hoping the student would engage with the [CWL community|http://common-workflow-language.github.io/#Community_and_Contributing]
- particularly for questions on interpreting the CWL specifications and possibly even improving
them. This engagement might include participating in development of the [CWL Java SDK|https://github.com/common-workflow-language/cwljava/]
- although for GSOC evaluation purposes we will concentrate on your direct contributions to
Apache Taverna.

h2. Mentors

An important part of GSOC is the personal mentoring from existing  members of the open source
community. Our job is not just to teach you how to successfully get through the GSOC programme,
but also to motivate you and make sure you progress. We will show you how to contribute to
open source, debug, improve, document, test and release your code as part of Apache Taverna.


The GSOC mentors for Apache Taverna have experience from guiding multiple earlier GSOC students
and local students, and can be contacted privately for day-to-day interaction and trouble-shooting.
