Unfortunately, DAS doesn't have any access control schemes built into it. This system is to store personal genomic data from customers of our sequencing service for (hopefully) thousands of individuals, so access control and privilege granting is going to be key. Though, there are a lot of solid ideas to get from this... and actually, some people on our system may opt to open their genome, and in that case, it seems like we could get a LOT of interop by implementing a DAS interface.
The ga4gh stuff is pretty interesting. I'd never heard of Avro before. I love the spirit of what they seem to be doing, but it seems like their API is currently only defined for accessing reads only (http://ga4gh.org/#/apis/reads/v0.1). Though, their Reference Variation stuff seems really interesting too.
Thanks for taking the time to check it out, Pierre. I was actually reading your blog earlier today! So, really cool to have someone with your knowledge looking over my document!
Access to what? What domain is this for? I'd like a way to organize a hundred genomes, only because they require a dozen harddrives right now.
