> Kundera as object datastore mapper and Cassandra combination looks matching for a NOSQL backend implementaion of Airavata registry that proposed in this project. Kundera JPA compliant provide capability of quickly persisting java objects into cassandra. And provide the capability to use native CQL for CRUD operations as well.It provide support for relationships between entities ,secondary level caching , composite key support over Cassandra , cross-datastore persistence and other salient feathers. please let me know your views regarding this.Thank you

>> 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.
