Marlon Pierce commented on AIRAVATA-341:
----------------------------------------
Hi Nipun--
Thanks for your interest. The registry has changed a lot since this GSOC
ticket was originally posted in 2012. We replaced the JCR system with a
relational database approach and OpenJPA. Please only trust what you read in
the code itself.
The registry is a critical piece of code in our work to get to Airavata API 1.0
(see the Jira entry Airavata-1000), since it will host the data objects we are
defining in Thrift. This will still be based on OpenJPA+Relational DB for the
time being, but it is also probably a great match for NoSQL DBs that act as
object stores.
If you are interested in this GSOC, I recommend following the Airavata API 1.0
discussion closely and watch also for changes in the current registry. Feel
free to contact the dev list, too, if you have questions or comments.

> Key: AIRAVATA-341
> URL: https://issues.apache.org/jira/browse/AIRAVATA-341
> Project: Airavata
> Issue Type: New Feature
> Reporter: Marlon Pierce

> Priority: Minor
> Labels: gsoc, gsoc2012, gsoc2014, mentor

> Airavata's Registry is used to store and retrieve services and workflows. The
> Registry is currently very lightweight with an implementation based on Apache
> Jackrabbit. This task is to develop a more powerful registry capable of
> handling a wider variety of use cases and science gateway metadata. Issues
> include development of JSON metadata models for different use cases,
> development and evaluation of metadata search capabilities (both
> expressiveness and performance), and development and evaluation of access
> policies for the metadata. The latter may involve integration with Apache
> Rave as an OpenSocial engine for defining groups and filtering requests.
> Evaluating the capabilities of multiple NoSQL databases will be an important
> component of this task. Candidate technologies from Apache include Cassandra
> and CouchDB, but appropriately licensed non-Apache projects such as MongoDB
> will also be evaluated.
> Sample use case scenarios will include computational chemistry, material
> science, astronomy, and earth science.
