Summary: Learning the Registry API
Key: AIRAVATA-409
URL: https://issues.apache.org/jira/browse/AIRAVATA-409
Project: Airavata
Issue Type: Sub-task
Reporter: Saminda Wijeratne
Airavata uses a registry as a storage for its metadata & userdata. Current
implementation of Registry API uses a JCR Registry (Jackrabbit specifically
speaking).
For starters look at the following aspects of the Registry API.
1. Type of data that is saved/searched/retrieved through the API
(actually that sort of sums up what the registry API for)
Once you understand the above as a small assignment try to do the following,
1. Try using the API
2. Try to see if you can cluster the functions in the API to groups based on
relevance. (eg: functions related to working with workflows, functions related
to host descriptions etc.)
3. Check to see if there exist any redundancy of functions defined.
4. If you are given the choice of redefining the API how would you rather do it?
Registry API consists of the following Interfaces
org.apache.airavata.common.registry.api.Registry
org.apache.airavata.registry.api.Axis2Registry
org.apache.airavata.registry.api.DataRegistry
The actual implementation is at,
org.apache.airavata.registry.api.impl.AiravataJCRRegistry
