Ok, I'll be very happy to see what you've accomplished there. I will read
through what you've done when I return from vacation in a week!
A key need is to have whatever data comes in show up as linked data in one's
history to avoid server overhead; a second objective was to not need to modify
existing workflows - as long as they could work of data in history that is
typed appropriately. So your 'select type' solution sounds intreguing!
And certainly interested in your use of git - I tried using git, using a 1-line
fasta data format, but git seemed to choke on protein fasta files? And did it
run into performance problems with larger files? That was my experience. I
think I read its authors say that its upper limit was 15gb. That was the
motivation for writing a simple key-value master file diff system that seems to
have the same I/O as git on smaller files, but more reliable for the fasta data
case, and no problems with larger files - it outputs a new version in the same
time it takes to read a master file. It has drawbacks though - incoming data
to compare master with must be sorted in 1 line fasta format first.
Thanks for your input; looking forward to your project writeup...

Subject: Re: [galaxy-dev] Concept for a Galaxy Versioned Fasta Data Retrieval
the idea sounds fantastic!
Can we go a step further and use a specific datatype that keeps entire
fasta files versioned and the user can choose which version he wants to
use, in any tool? Please have a look at my talk at GCC2012. Maybe you
are interested in the (old) patches. I would be very interested to
restart this old project.

I think all of the use cases are covered by the old project mentioned
above. But I did not create a new tool I have created a new 'select
type' everyone can use in all tools. It was using git underneath (yeah,
I have the entire PDB in git and it is working fine :)) but we can
probably change git with a database if you like.
To answer your question: Yes, very attractive!

Yes, as long as the User has an API key.
