Cataloging Demo Release

We’re very proud to announce the release of the Evergreen Cataloging (Pre-Alpha) Demo. Again, this is a pre-alpha version meant simply for demonstration and proof of concept. There are many, many bugs in this release, and it has limited functionality. The purpose for this release is to gather feedback and to determine if we’re generally heading in the correct direction. We are not looking for bug reports or detail-oriented feedback. The time for that will come later, after the Alpha release this summer.

With those caveats in mind, here are some of the specific functionalities this release contains:

The birth of OpenSRF

After months of work, buckets of sweat, and one snapshot of code seemingly unrelated to libraries, we are proud to present our first subproject: OpenSRF (Open Scalable Request Framework), pronounced “open surf”. The 0.1 release of OpenSRF represents the culmination of everything we have posted about here, and some things we haven’t.

One of the main differences between our initial snapshot tarball and the shiny new OpenSRF code is the removal of the dependence on an Auth Application. We have decided that the security provided by Jabber is sufficient for connection to the OpenSRF network, and application level authentication and authorization should be handled either by each individual Application, or by an Authentication Application built specifically for the target problem domain.

The Router : More on Communication

We’ve recently completed version 0.1 of what we call, simply, “The Router”. Someday a different loving name will likely fall from the sky, but until then…

The Router is more accurately described as a Jabber Request Load Balancer and Message Router/Broadcaster. Our main use is to employ The Router balancing client requests across a redundant array of application servers. Now take that idea and multiply it across a set of routers (probably one per Jabber server or Jabber domain) and you have a Jabber communication web that’s intelligent enough to recover from the loss of any single node (jabber server, Router, application server).
