Membership

Currently, a person becomes a member of a community when they are added to the community group. This group serves both as a list of members, and a source of truth for data access.

Joining a Community

Person becomes a member when they are added to the community's group.

Open groups

A person sends a Join activity to community's inbox, and gets added immediately.

Invitation-only (not implemented)

Join using an invitation, or get added by other person.

Access to resources

Other community members need read access to the hospex profile and accommodations.

WAC

A resource's .acl can have acl:agentGroup predicate pointing to a public community's vcard:Group document with a list of members. This is a primary way of sharing data at the moment. The downside is it's centralized and community breaks down if the community pod disappears.

Alternatives:

• vcard:Group document can be stored in each member's pod and updated with a dedicated service or by copying it from contacts.
• each person can be listed via acl:agent in each .acl document.

ACP

Currently not supported. Would work well if ACP Matchers could be reused. Then we could have a central list of members, or a list for each member, similar to vcard:Group for WAC.

Leaving a Community
