[Building Sakai] resources entity Broker development

[Adam Marshall]

We are just about to embark on a Resources Entity Broker API (incl. Citations) and I just wanted to check that we know about all previous work.

I see 

https://jira.sakaiproject.org/browse/SAK-21211 

https://jira.sakaiproject.org/browse/SAK-20698

https://jira.sakaiproject.org/browse/SAK-15196 - citations

Q1 - are there any other related Jiras?

Q2 - has anybody done any work not included above / not committed?
