How can I get the list of users in a project area using OSLC in RTC?

To access member info, use process RESTapi (note this is not OSLC).

For example, if you have  jazzhub.example.com/ccm01 instance, then access like

  https://jazzhub.example.com/ccm01/process/project-areas/

This will list all projects that you can access. Then you can find member list access URL like this.

  https://jazzhub.example.com/ccm01/process/project-areas/_ZhogejmEeKhontp5lzEQ/members

Where _Z** is a project ID. If your project is nested, then open team area, you will find similar structures.

Hope this helps !

by users if you mean members of a specific project area, they can be reached using:
     https://localhost:9443/ccm/process/project-areas/_JQuZcFNcEeKhkuM6LJfdVw/members

all users of the repository can be reached through:
    https://clm40.in.ibm.com:9443/ccm/oslc/users


Discovery Mechanism:

1.  Starting with CCM Root Services
    https://localhost:9443/ccm/rootservices

2.  Find the Project Areas URL
    <jp06:projectAreas rdf:resource="https://localhost:9443/ccm/process/project-areas"/>

3.  Find members URL against specificc project areas   
    <jp06:project-areas>
        <jp06:project-area jp06:name="CustomReminderPoC">
            <jp06:summary>CustomReminderPoC</jp06:summary>
            <jp06:description/>
            <jp06:url>
                https://localhost:9443/ccm/process/project-areas/_JQuZcFNcEeKhkuM6LJfdVw
            </jp06:url>
            <jp06:roles-url>
                https://localhost:9443/ccm/process/project-areas/_JQuZcFNcEeKhkuM6LJfdVw/roles
            </jp06:roles-url>
            <jp06:links-url>
                https://localhost:9443/ccm/process/project-areas/_JQuZcFNcEeKhkuM6LJfdVw/links
            </jp06:links-url>
            <jp06:members-url>
                https://localhost:9443/ccm/process/project-areas/_JQuZcFNcEeKhkuM6LJfdVw/members
            </jp06:members-url>
           
4.  Using the jp06:members-url the list of members is reached:
    https://localhost:9443/ccm/process/project-areas/_JQuZcFNcEeKhkuM6LJfdVw/members
       
Sample:
    <jp06:members jp:total-members="3">
        <jp06:member>
            <jp06:url>

hope it helps.

Thank you Dinesh & Takehiko for very quick responses !

Yes, I mean members of a Project Area and in current situation I have been trying to list for RM Project.

https://my.rmhost.ibm.com:19443/rm/process/project-areas/_z6ILABQKEeWGrt9v24XbYA/members

I am able to see the data of members in the XML format.

Is it possible to get it in user friendly format : .xls ?

 is it possible to fetch users without UUID? just by giving input as project area name?

 I have questions about what the true question is about. Why do you want to get the list of members of the project area?  Do you also want the members of the team areas?  Do you want to know what role the users have for a given team area?  Is using a REST call the only option for getting the information or can you use the Java API?
