The invention provides a Web service which enables a publisher to share
his digital resources such as an address card or a calendar with a number
of subscribers based on different sharing relationships. The Web service
includes a host-based interface called "My Community", for example, with
which the publisher manages the share-relationships with his community
members. The community members are organized into different groups. Each
group includes a number of community members who have a common sharing
relationship with the publisher with respect to one or more views of the
shared resources. A resource may have multiple views. Each of the views
has Metadata describing sharing-styles, as well as version, creation
date, size, and the like. Each sharing style corresponds to a specific
sharing relationship between a community member and the publisher.
