Greetings.

I'm getting questions about requesting restricted data through EMERALD. Do
you have an estimate as to when that functionality will be available?

Thanks!

    Hi John,

    As a conservative estimate I would say that access to restricted data via web services should be in place in early next year. I'm hopeful it'll be sooner but there are a lot of details involved.

    As a bit of insight into what we're doing: the DMC old (current) access was not a good fit for access via services, a password was specific to a data set and shared between researchers. We needed a new paradigm in which a users' personal password will give them access to all the data sets they are allowed to access. At the same time we modernized the internal password management at the DMC. A message has been drafted explaining the details to those users with restricted data sets, but in short you'll be able to use the same data web services and provide a username and password to get access to your data. HTTP Digest Authentication will be used, it's standard and well supported by nearly all HTTP clients/toolkits.

      In the mean time, you can access restricted data with DHI. It would
      not be much of an effort to put a thin web services wrapper around the
      existing DHI seismogram server and to allow this now.

      Revamping restricted data access password sounds like a good idea. Old
      system was always a bit weird.

      Just my $0.02

        My guess is we have different ideas of how much effort it would take. Also, since DHI will be retired after Jun 30th next year it would be temporary at best.

        Revamping restricted data access password sounds like a good idea. Old
        system was always a bit weird.

        Yeah, we think so too. When the old system was started decades ago it was a pretty good fit for the problem, moving into DHI and then web services it's less convenient.

          Hi John

          I have put up a tarball that handles the proxy for a dataselect style
          web service to a DHI seismogram server to allow access to restricted
          data. See the ReadMe in the tarball for how to use it.

          http://www.seis.sc.edu/~crotwell/dataselectDHIProxy/

          All a bit rough, but seems to work for my limited testing. Not bad for
          a couple of hours in the morning.

          You might want to look at bit at this to see how it is done in SOD,
          which is closely related to this code:
          http://www.seis.sc.edu/sod/documentation/restricted.html

          Enjoy, and let me know if you find any issues.
          Philip
