work-around
In version 1.2, the web interface does not allow the creation of membership relationships for committees. That is, while one is logged in to do edits, one can click on the plus sign on "Member Of", but there is no choice for committees. Inversely, if you are on a committee page, there is no plus sign to add members to the committee. This will be fixed in future versions of VIVO. For now, the following workaround can be used to create committee memberships.
Note: To execute the following procedure, you must be signed in as an administrator
Voila! You told VIVO the committee was also an association. Then added members to the association, then told VIVO the committee was no longer an association. All the memberships are intact.
You can also use this procedure at any time to add more members to the committee.
