Together, og_sites_hub and og_sites provide multisite functionality in which a central 'hub' site has a set of associated sites leveraging Organic Groups functionality to selectively share data (nodes and users), such that the hub site has access to all data while associated sites see and edit only their own data plus that specifically shared by the hub site.

OG Sites is rough and incomplete--it was drafted for the first stage of a client project that didn't go forward. Documentation and support are both very limited. There are no current plans to upgrade OG Sites beyond Drupal 5.

This module will be particularly useful to, e.g., an organization or company with a head office and many branch office, or a network wanting a central site.

By default, Drupal supports table sharing between sites. In a multisite configuration, however, it is often desirable to selectively limit access between sites. For example, with simple table sharing, an admin user on one site could reset the password of user 1 on another site, gaining full control over that other site.

Control over access is especially needed in a configuration where one site is a network hub, with many associated sites--e.g., an organization with a head office and many branches. Under this configuration, the hub site needs access to all users and content, but the branches should only have access to their own content and users.

og_sites_hub runs on the hub site. It maintains links between users, groups, and content. Each associated site is represented by an organic group on the hub site.

og_sites runs on each client site. It registers all users and content with the site's group on the hub site and restricts access to users and content created on the client site or associated with the client site's group. There is also a group created on the hub site that allows publishing of content that will be visible on all associated (client) sites.
