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.
