>>
>> # Background
>>
>> Taverna workflows coordinate inputs and outputs between computational
>> processes and Web Services. The workflow is designed in a graphical

>> representing processes and their data connections. The different
>> processes in a workflow can be command line tools, REST and WSDL Web

>> filtering, cleaning, integrating, analysis and visualization. Taverna
>> calls these processes "services", as they generally are provided by
>> remote (third-party) servers.
>>
>> These kind of computational workflows, also known as pipelines and
>> dataflows, focus on the movement of data rather than the execution
>> order of the underlying processes. Features such as implicit
>> iterations (where an input list of values causes multiple process
>> executions) and parallel invocations (independent processes are
>> executed as soon as their data is available) are intrinsic to a
>> dataflow system, not requiring any particular constructs by the
>> workflow designer.
>>
>> As a visual programming environment, workflows aids collaboration and

>> * Move Github repositories to Apache git
>> * Automated builds in Apache's Jenkins
>> * Update to latest releases of Apache dependencies

>> # Current Status
>>
>> ## Meritocracy
>>
>> Taverna was initially created by the myGrid consortium in 2003. Since
>> 2006, the majority of contributions to Taverna's core code-base, its

>>)
>> and integrations
>> (http://www.taverna.org.uk/developers/work-in-progress/taverna-online/
>> http://www.taverna.org.uk/download/associated-tools/).

>> core distribution (e.g. External Tool plugin by Möller and Krabbenhöft
>> and AstroTaverna by Garrido), or when their development has required
>> patches to the existing code base.
>>
>>
>> ## Community
>>
>> Taverna has an active community of plug-in developers and users. The
>> developer mailing list (taverna-hackers@lists.sourceforge.net) has 248
>> members, the user mailing list (taverna-users@lists.sourceforge.net)
>> has 370 members.
>>
>> 1500 users have registered as of 19 August 2014. Total downloads of
>> all products since version 2.1 (released December 2009) is 35000.
>>
>> A Taverna Developer workshop is being arranged for 30 October 2014 to
>> bring together developers and integrators of Taverna. We want to
>> encourage plug-in developers to participate further also in the core
>> development of Taverna, by introducing them to the code base and how
>> to contribute. 
>>http://dev.mygrid.org.uk/wiki/display/developer/Taverna+Open+Development+
>>Workshop
>>
>> Active steps to grow the communities of users and developers by
>> targeting specific research domains such as the work by Kevin Benson
>> on Taverna's use in the Heliophysics and Astrophysics community.
>> Susheel Varma is increasing usage of Taverna within the Biomedical
>> domain. Julián Garrido and his work on AstroTaverna is promoting
>> Taverna within the IVOA Virtual Astronomy community. Sonja Holl and
>> Björn Hagemeier's are targeting high performance computing.
>>
>>
>> ## Core Developers
>>
>> What we currently consider to be the core Taverna Team is (in
>> alphabetical order):
>>
>> Christian Brenninkmeijer (University of Manchester)
>> Donal Fellows (University of Manchester)
>> Robert Haines (University of Manchester)
>> Aleksandra Nenadic (University of Manchester)
>> Dmitry Repchevsky (Barcelona Supercomputing Center)
>> Stian Soiland-Reyes (University of Manchester)
>> Shoaib Sufi  (University of Manchester)
>> Vadim Surpin (Institute for Information Transmission Problems in Moscow)
>> Alan Williams (University of Manchester)
>>
>> The team consists of experienced developers who have worked on a
>> multitude projects, particular within writing software for supporting
>> scientists. The committers list (See below) includes additionally
>> plugin developers whose contributions have become part of Taverna.
>> Part of our desire to join the Apache Foundation is to recognise their
>> effort and promote them into also being "core developers".
>>
>>
>> ## Alignment
>>
>> Taverna dependencies include Apache Commons, Axis, Abdera, Batik, CXF,
>> Derby, Felix, HttpComponents, Jena, log4j, Maven, POI, Velocity,
>> Xerces, XMLBeans, Xalan, We use Tomcat for testing and deployment of
>> the Taverna Server.
>> As part of moving to Apache-compatible dependencies, Taverna will
>> probably adopt OpenJPA to replace (LGPL) Hibernate.
>>
>>
>>
>> # Known Risks
>>
>> ## Orphaned products
>>
>> Most of the core developers are from the myGrid team at University of
>> Manchester, but are funded through a series of projects - see
>> http://www.mygrid.org.uk/projects/. Many of these projects incorporate
>> Taverna, so the effort from Manchester is partially based on direct
>> project requirements, but also partially a volunteer effort for
>> project maintenance and general development. The myGrid team has
>> guaranteed funding until 2017.
>>
>> The developers that are outside Manchester are generally funded for
>> other activities, and so their effort to Taverna is to a greater
>> extent a volunteer effort - although again project-specific
>> requirements steer their effort (e.g. for a new Taverna plugin).
>>
>> One of the reasons for our desire to move to the Apache Foundation is
>> to formalise this volunteering/contribution effort so that it becomes
>> obvious that it is not just University of Manchester that is
>> contributing to the core code base - and therefore reducing the
>> impression that Taverna is vulnerable to Manchester¹s future funding
>> and projects.
>>
>>
>> ## Inexperience with Open Source
>>
>> Taverna has been an open-source project since its first release in
>> 2003. Most of the contributors also have experience with working with
>> and contributing to other open source projects (e.g. TCL, CXF, Jena),
>> particularly as Taverna strongly relies on other open source tools.
>> Most of the research projects which the myGrid members have
>> participated in produces open-source software.
>>
>>
>> ## Homogeneous Developers
>>
>> The committers list includes many people from myGrid, University of
>> Manchester in United Kingdom - but these developers have been working
>> on a range of distributed and European projects in the field of
>> scientific software - see http://www.mygrid.org.uk/projects/
>>
>> The other developers on the committers list come from many different
>> projects and institutions across the world, from Russia, Canada,
>> Germany and Spain.
>>
>>
>> ## Reliance on Salaried Developers
>>
>> Development for Taverna is mainly performed as part of the developers'
>> salaried work, but funded through many different projects at several
>> institutions (see above). These projects don't generally have
>> "contribute to Taverna" as their main goals - so therefore in many
>> ways the effort is still volunteer-based - contributing to Taverna as
>> a way to support one's own work.
>>
>> From our experience of running Taverna over the last 10 years, new
>> contributors will continue to join as Taverna becomes an ingredient in
>> new projects, while existing contributors more slowly fade out of
>> their involvement. Often existing contributors and users gives the
>> personal link to the new contributors.
>>
>>
>> ## Relationships with Other Apache Products
>>
>> Apache already contains projects that seem relevant to Taverna.
>>
>> Apache Pig https://pig.apache.org/ is a high-level language for
>> creating Map-Reduce programs for Apache Hadoop. There already exists
>> third-party efforts to convert Taverna Workflows to Hadoop and Pig -
>> https://github.com/umaqsud/taverna-to-pig
>> https://github.com/schenck/taverna-to-hadoop (thus making a graphical
>> interface for building Apache Pig workflows) - and part of the Apache
>> Taverna effort would be to invite these to join the project.
>>
>> Apache Airavata http://airavata.apache.org/ is a software framework
>> for executing and managing computational jobs and workflows on
>> distributed computing resources. Taverna's concern is not as much job
>> coordination, but more of a data flow between services. Airavata's
>> XBaya Workflow Suite can export workflows in Taverna 1 format SCUFL,
>> but could be updated to work with Taverna 3's SCUFL2 format.
>>
>> Apache ODE https://ode.apache.org/ is a WS-BPEL workflow engine. BPEL
>> as a workflow language is quite verbose compared to dataflow languages
>> like Taverna, and is additionally bound to a particular protocol
>> (SOAP). Nevertheless,  a sub-section of Taverna workflows could in
>> theory run on the Apache ODE engine - and the Taverna 3 Platform API
>> has facilities for plugging in alternative workflow engines. We have
>> previously considered Apache Hadoop as one such alternate engine for
>> executing a different subset of workflows with local command line
>> tools.
>>
>> Apache Storm http://storm.incubator.apache.org/ is a distributed
>> realtime computation framework. Experiments are under development to
>> use Taverna as a front-end for creating Apache Storm workflows -
>> http://markmail.org/message/zg5ylo2aucpwfc5j
>>
>> Apache has several popular frameworks for building REST/SOAP web
>> services (Apache CXF, Apache Clerezza),  data services (Apache Jena,
>> Apache Hive, Apache CouchDB) and specific workflow engines (Apache
>> Oozie for Hadoop, Apache ODE for WS-BPEL). Taverna as a general REST
>> and SOAP service client can be used for combining, testing and
>> demonstrating such services.
>>
>>
>> ## A Excessive Fascination with the Apache Brand
>>
>> Taverna is a long-running project (since 2003) with an existing user-
>> and developer base across the academic world. Our main motivation for
>> moving to Apache is to further encourage an open development process
>> and engage existing and new developers to contribute to the core code
>> base.  We also want to ensure long-term continuity of the Taverna
>> products, and for its future directions to be decided by the whole
>> Taverna community rather than one of the parties involved.
>>
>>
>>
>> # Documentation
>>
>> Taverna's documentation is available from
>> http://www.taverna.org.uk/documentation/taverna-2-x/, including an
>> extensive user manual at
>> http://www.mygrid.org.uk/dev/wiki/display/taverna/User+Manual and
>> tutorials http://www.taverna.org.uk/documentation/taverna-2-x/tutorials/
>> and videos http://www.taverna.org.uk/documentation/taverna-2-x/videos/.
>>
>> The developer documentation
>> http://dev.mygrid.org.uk/wiki/display/developer/Developers+Guide
>> includes tutorials
>> http://dev.mygrid.org.uk/wiki/display/developer/Tutorials for working
>> with Taverna's source code and creating plugins.
>>
>>
>> # Initial Source
>>
>> Taverna's source code is available from the 'taverna' github team
>> account: https://github.com/taverna/. These 85 git repositories
>> reflect the current modules of Taverna's plugin system after recently
>> transitioning from Google Code SVN at
>> http://taverna.googlecode.com/svn/taverna/. The history of Taverna's
>> code base goes back to being hosted in CVS at SourceForge
>> http://taverna.cvs.sourceforge.net/, transitioned as of
>> http://taverna.googlecode.com/svn/archived/cvs2svn-2008-09-25/. Note
>> that reasonable steps have been made to preserve commit history when
>> moving between version control system, this has not always been
>> achieved when moving between modules and refactoring larger Java
>> packages. Some source files might therefore in git have initial
>> commits like "Moved from /taverna/utils/trunk" referring to SVN paths.
>>
>> One of the reason for many repositories is that we rely on Apache
>> Maven and a plugin system (since Taverna 3 OSGi-based) where different
>> modules have different version numbers and release cycles (e.g.
>> tags/branches). This is essential for the plug-in support of Taverna
>> as the plug-ins depend on the semantic versioning of the APIs and
>> required implementations.
>>
>> It is however in our current plans to merge repositories that have
>> similar release cycles and greatly reduce the number of repositories.
>>
>> Taverna source code uses the package names (and children packages):
>>
>> net.sf.taverna - since Taverna 2
>> uk.org.taverna  - new from Taverna 3
>> org.taverna (sic) - Taverna Server
>>
>> Some contributed code uses package names depending on their
>> originating projects:
>>
>> org.purl.wf4ever.provtaverna
>> org.biomart.martservice
>>
>> We intend to release only the upcoming Taverna 3.0 version under the
>> Apache umbrella (not 2.x) - therefore, according to semantic
>> versioning rules http://semver.org/, the transition period of the
>> Apache Incubator would be the best (and possibly only) chance to
>> rename Java packages and Maven groupIDs to org.apache.taverna.* Under
>> OSGi the packaging and JAR goes hand-in-hand (several JARs don't
>> normally provide the same package), and therefore any package rename
>> would be done together with the repository restructuring.

>> # External Dependencies
>>
>> Taverna, as an integrating workflow system, has a fairly large number
>> of dependencies - the latest 2.5.0 Core Workbench distribution has 517
>> JARs (although many of those are duplicates in different versions)
>>
>> We are intending for our first Apache-based release to be Taverna 3,
>> which has already reduced this dependency list.
>>
>> We have performed an analysis of our dependencies of Taverna 3 at
>> http://dev.mygrid.org.uk/wiki/display/developer/Taverna+Dependencies -
>> but this is not yet a complete list.
>>
>> A second analysis looks at the license of those dependencies at
>> http://dev.mygrid.org.uk/wiki/display/developer/Third-party+licenses -
>> where we have some incompatible (LGPL) dependencies. Most of these are
>> resolvable as they are part of optional plugins to Taverna (e.g. R
>> support, BioMart). The dependency on Hibernate requires some developer
>> effort to be replaced with either Apache Open JPA or a "No-SQL"
>> solution.
>>
>>
>> # Cryptography
>>
>> Taverna uses these cryptography dependencies:
>>
>> BouncyCastle
>> OpenJDK builds with the default JCE full encryption policy (bundled in
>> installer)
>>
>> Taverna utilise these to form of an encrypted keystore (storing
>> username/password and client certificates for third-party services
>> accessed by the designed workflow) with corresponding user interface,
>> and additionally binds to Java's SSL support to provide UI and command
>> line options for security interactions, e.g. accepting new server
>> certificates, or asking for username/passwords for HTTP Basic
>> authentication (which can then be stored in the keystore).
>>
>>
>> # Required Resources
>>
>> Taverna currently relies on a mixture of infrastructure hosted for
>> free by third-parties (e.g. Github, SourceForge, GoogleCode,
>> Launchpad, Bitbucket) and infrastructure hosted by myGrid at
>> University of Manchester (Jenkins, Jira, Confluence, Wordpress).
>>
>> ## Mailing lists

>> ## Issue Tracking
>>
>> JIRA Taverna (TAV)
