How to add members to Project Area in Rational Design Manager programmatically

For RTC, QM, RDNG it is possibl eto use the RTC Plain Java Client libraries and the code would be the same like below. I have no example for OSLC. Most likely there is no OSLC spec. There might be REST services you could use.


    /**
     * Adds users and roles to a project area.
     *
     * @param teamRepository
     * @param area
     * @param monitor
     * @return
     * @throws TeamRepositoryException
     */
    private IProjectArea addUsersAndRoles(ITeamRepository teamRepository,
            IProjectArea area, String userID, String roleID, IProgressMonitor monitor)
            throws TeamRepositoryException {

        IProcessItemService service = (IProcessItemService) teamRepository
                .getClientLibrary(IProcessItemService.class);
        area = (IProjectArea) service.getMutableCopy(area);
        System.out.println("Trying to add member with roles: "
                + roleID + " to Project Area" + area.getName());

        IContributor user = teamRepository.contributorManager().fetchContributorByUserId(userID, monitor);
        //area.addAdministrator(user);
        area.addMember(user);

       
        IRole role = getRole(area, roleID, monitor);
        area.addRoleAssignments(user, new IRole[] { role });
        @SuppressWarnings("unused")
        IProcessItem[] items = service.save(new IProcessItem[] { area },
                monitor);
        System.out.println("Users with Roles added to " + area.getName());
        return area;
    }

    /**
     * Gets a role by its ID.
     *
     * @param area
     * @param roleID
     * @param monitor
     * @return
     * @throws TeamRepositoryException
     */
    private IRole getRole(IProcessArea area, String roleID,
            IProgressMonitor monitor) throws TeamRepositoryException {
        ITeamRepository repo = (ITeamRepository) area.getOrigin();
        IProcessItemService service = (IProcessItemService) repo
                .getClientLibrary(IProcessItemService.class);
        IClientProcess clientProcess = service.getClientProcess(area, monitor);
        IRole[] availableRoles = clientProcess.getRoles(area, monitor);
        for (int i = 0; i < availableRoles.length; i++) {
            IRole role = availableRoles[i];
            // IRole2 role2 = (IRole2)role;
            // role2.getRoleName();
            if (role.getId().equalsIgnoreCase(roleID))
                return role;
        }
        throw new IllegalArgumentException("Couldn't find roles");
    }

 This is the response from IBM David Hirsch
RDM SDK currently doesn't support creating project areas or adding members to it.
The creation of project areas is provided by jfs. 
RTC SDK (to my best knowledge) is using the jfs client libraries to provide the service of manipulating projectareas.
Currently dm sdk is not build on top of the jfs clients. As a result we cannot provide this service out of the box.
