[DAS2] paper? was: Re: Notes from the biweekly DAS/2 teleconference, 2 Apr 2007

Mon Apr 2 18:19:27 UTC 2007

Dear all,

Sorry I didn't come to the meeting today!

I just  wanted to ask about the DAS2 paper. The BioMoby group are
working on a draft, and it seems to be near finishing. If you are at
the proper stage for it, it would be terrific if the DAS2 project
could be published soon, since the two projects have similarities. I
expect that if the two papers came out at about the same time, some
"buzz" could be generated over bioinformatics Web services, which I
expect would be great for both projects. Also, it would be good to
explain how the two approaches are complementary, and not competing.
If people think the two are doing the same thing, then support would
be harder to get.

btw, the BioMoby draft is under version control in the BioMoby cvs
repository. It might be good to take a look.

All the best!

Ann
