The main reason why you perhaps might perceive to hear less from other
developers like me is that Alan Williams has taken the permanent
responsibility of having the support hat. Previously we switched the
hat every second week, which meant that typical questions/problems
would be replied to by different Taverna developers would reply.
That you don't see that many emails from the other developers does not
mean that they don't work hard.
If you want to see what the myGrid team is up to generally, feel free
to follow the minutes at [1].
Here's a quick summary of what's going on behind the scene,
myGrid-ers, feel free to correct any mistakes or unclear statements:
In not any particular order, let's hope I didn't forget anyone:
Ian Dunlop is a developer working on a project called Obesity e-Lab
[2] about gathering data sources in obesity study. This is part of the
larger myGrid e-Labs initiative. He will also be working on
integrating the provenance / intermediate values for Taverna 2.1.
Paolo Missier is a researcher working with Taverna provenance (also
called "log book"), and in addition to developing the storage and
query mechanism for provenance in Taverna 2, he's investigating data
lineage queries ("where did this data come from") and query execution
time. The provenance is there in the code of 2.0, but it's not exposed
in the user interface, which is what we'll be adding for 2.1 or 2.2.
Stuart Owens is a developer involved with Sysmo-DB [2], a systems
biology project concerned with data exchange, and they will be using
(and extending) technology such as Taverna, SBML and myExperiment for
this work. He's also currently looking into BioMoby updates and doing
a Taverna 1.7.2/1.7.1.1 release.
Alan R Williams is a developer managing the myGrid/Taverna
documentation [4] and website [5], requirement gathering (such has
this original email thread), making usability prototypes and
improvements to Taverna, in addition to planning the Taverna roadmap
[6] and managing the reported issues [7].
Steve Pettifer is a lecturer in Human Computer Interaction,
Visualisation, 3D Graphics and Distributed Systems, who's working on
improving the Taverna user interface, in addition to building
alternative frontends such as Utopia [20].
Alex Nenadic is a developer and has been working on the Taverna-caGrid
cooperation [7], including the work of wrapping services for caGrid.
She will also be working on the support for secured caGrid/Globus
services for Taverna, as she has previously worked on the foundation
for this in Taverna 2, like the credential manager. She has also done
many user interface improvements, and is currently working on
improving the Workflow explorer, Service palette and the Run dialogue
for Taverna 2.1. You can preview the work already done (mainly the
Explorer so far) by downloading the latest nightly snapshot [11] - the
-bin.zip file should unpack and run out of the box.
Stian Soiland-Reyes is a developer who has also been involved in the
Taverna-caGrid work, like supporting the development of the Taverna
caGrid plugin [8]. He has recently done a code restructuring of the
Taverna 2 code base to simplify development on Taverna 2 for the team
and outside developers, in addition to providing automatic builds
[10]. The documentation for this [9] is being completed, after which
we will officially invite the hackers to use the new code base from
the Subversion repository (and do the last migrations from CVS). He's
currently working with Alex on the UI improvements.
Tom Oinn was the lead architect who in addition to have done most of
the original foundation for Taverna and Taverna 2, lately has written
the Taverna 2 platform [13], and demonstrated this at the last Taverna
developer workshop in Manchester [14]. He now runs his own independent
software architecture consultancy, Cryptic Squid [15].
Constantinos Astreos is administering the myGrid project, working
closely together with Carole Goble with external actors, including
partnering with commercial companies. He's also planning how the
different projects gets allocated time from the myGrid developers, in
addition to being involved with the administration of the
Taverna-caGrid project [7]. He's also managing the eScience North West
Centre [12].
Carole Goble is basically supervising everything, presenting myGrid
and Taverna for various events, managing the funding for myGrid and
other projects. She's also one of the OMII-UK [13] Principle
Investigators. I'm not able to cover everything she's involved it,
it's sufficient to say that we feel privileged when we get a slice of
a time, which luckily we do quite often.
Katy Wolstencroft is a bioinformatician who has been working on
BioCatalogue [17], and currently working on Sysmo-DB [3] . She's also
doing lots of outreach work, presenting and teaching Taverna to
academic and commercial entities around the world, in addition to
making screencast videos of Taverna [4] and writing a book about
writing Taverna workflows together with Carole Goble.
Paul Fisher is a bioinformatician, who in addition to writing and
sharing all his workflows on myExperiment [18], is working on the
ONDEX project, exploring and writing workflows that roughly explained
can gather data from various services, populate an ONDEX graph, and do
interesting stuff with this graph afterwards finding new connections.
Paul also presents Taverna and his work at various events.
Franck Tanoh is a bioinformatician who has annotated lots of services
for Feta and for BioCatalogue. He's been working with BioCatalogue
[17] on requirements for annotating services, and has also been
involved in the Taverna-caGrid integration [7]. Franck also presents
and teaches building of Taverna workflows at different events
worldwide.
Sergejs Aleksejevs is a developer who has worked on myExperiment [19],
and lately also worked on the Sysmo-DB [3] project. He's currently
porting the myExperiment plugin for Taverna to work with Taverna 2, in
addition to improving the "Run workflow from web" solution of
myExperiment.
Jiten Bhagat is also a myExperiment [19] developer, who is currently
working on the BioCatalogue project [17], which you can think of as an
myExperiment for web services. (A web 2.0 "service registry").
BioCatalogue is considered a highly important piece for the bigger
Taverna picture, further ahead Taverna will be able to connect to the
BioCatalogue to find and discover services.
Shoaib Sufi is working on the eLabs initiative, where he among other
things is currently building an ontology for describing and linking
different projects. He's also involved in the eObesity labs [2]
project.
David Withers is a developer working with the ONDEX project [16],
where he has built a Taverna-friendly web service front-end of ONDEX.
He's also working on the Shared Genomics project where he has built a
RESTful web service for running Taverna workflows, this is based on
the Taverna 2 platform. This will be released next month. David has
also been involved with improving the data reference service in
Taverna 2 to handle large data, in addition to complete the work for
the Taverna 2 platform.
As you might see, we *are* working a lot, but it's true to say that
not all of this work is direct work on the Taverna source code. Much
of the "other" work does however benefit Taverna, in either getting
new partners, new extensions and new platforms to support the bigger
picture where Taverna fits in.
The "main" Taverna developers right now are Alex, Stian and Alan. Ian
and Paolo is contributing for the provenance, David for the data
storage and the t2 platform, while Stuart is looking at doing a
Taverna 1.7.x release.
What we can have a (hopefully not too long) discussion about is about
how we can involve third party developers more in the actual
development of Taverna. The restructuring and documentation [9] of
this is part of that work that we want to include you guys more and
earlier. For instance we will now have nightly snapshots that you can
run out of the box, and see what are the latest features.
