Objects include collections, links, and all sorts of documents. Access rights can be given to single users or user groups. The rights are specified in the attribute Rights .
Users have to have read access to view a document.
In contrast to WWW, in Hyperwave every user can be an author, and thus we need to specify write access rights. Write access implies read access. This right is attached to collections, and defines which users have rights to delete objects in this collection. If no unlink rights are defined, those who have write permission also have unlink permission. This right is needed if you want to use a collection for a group discussion where many users should be able to insert their own documents, but not to delete others.
