Suggestions/Comments from the Group

- Leif Johansson, NORDUNET, suggested that Grouper provision groups like OAuth does. 
  A reference is the VOOT protocol, a subset of the OpenSocial protocol:

- University of California System is interested in workflow tools to get data into groups. The workflow tools don't have to be part of Grouper, but integrated with it. 

- University of California System is also trying to get information about permissions about UC schools together into one place and provision groups into the central system. UC could sync across Grouper instances. 

- Grouper may have enough connecting bits that custom code would not be needed to get permissions populated, but it would be good if a campus could try this out. 

- It would be great to have a catalog of services/applications that people could review and request access. This may be naive, but could have merit. There's now a Grouper request process that campuses can use to fulfill requests. 

Q: Can the UI work be moved up in the schedule?
A:  Yes. Currently, the Grouper development team is working on the process for how to determine requirements for the UI. If you're interested in this, please join the upcoming Grouper-Dev calls.
Q: Can an external subject assign groups and members etc.?
A:  Yes. 

Q: What is being done on outreach to scientific projects that tend to reinvent the wheel?
A:  The Grouper Project Team understands the additional need for more outreach and training and are working on plans.

- Grouper needs better packaging and easier install. The developers understand this and may move the Grouper Loader into the web services. LDAPPC-NG has potential for more generic business system integration so still may be kept separate. 

- Grouper would benefit from a third-party support organization. Campuses need third party support to build the case for management. Unicon is talking internally about Grouper support, but not sure about the demand and would be interested in more information about this.
Q: Can organizations engage Unicon directly w/o a formal support program? 
A: Unicon would support Grouper if someone requested it.

Q: Group naming is the biggest issue with deployment. Can group naming be changed later? 
A: Yes it's possible.
