I just noticed this blurb in the latest BioInform, 20 July 07:

> Japan¹s RIKEN has released an update for the OmicBrowse genome browser, which
> displays an integrated view of multiple omics annotations filtered with
> ontologies. New functions include access controls over secure datasets, the
> ability to change the browser's window size, and genome annotations for human,
> mouse, rat, C. elegans, Arabidopsis, and rice.


They provide a Flash-based client, Java servlet-based server, and a DAS/1

They don't cite any spec or other document describing this protocol:


It has some interesting comparative genomics capabilities:

Anyone have experience with it or understand exactly how SDAS works relative
to DAS/1 or DAS/2?
