About
The
DAS registration service provides a repository
for registry and discovery of
DAS (Distributed Annotation System)
services. DAS servers are described with meta
data like who is providing a server, what DAS commands are being understood by it,
what type of data is being provided, etc.
DAS style XML-http as well as SOAP based web services can be used to
interact with the DAS registry.
This is used by
DAS clients like
EnsEMBL,
SPICE,
or
Dasty
to retrieve the list of available services.
In the future
DAS servers like
Dazzle
or
Proserver
perhaps can automatically connect to the registration service and register or
renew the lease for a DAS service.
Projects
Projects that fund DAS sources can be acknowledged.
We are currently in the process in adding support for this also on the DAS client side.
I.e. next to a DAS track the logo of the funding project should be displayed.
Validation
The registration server contains a
validation
mechanism, to make sure that a DAS source is registered properly. When
registering a new service an accession code (segment id) needs to be
provided. This is used to create a DAS request and validate the
response. A service can only be registered if the provided accession
code returns a DAS response that contains data.
To prevent the registration service from keeping track of old or even
non-functional DAS services, a
lease is assigned to each. If the
lease
is not renewed for a long period, a server might be removed from the
registry, after a warning has been submitted to the administrator of the
DAS service.
