ODS-Calendar WebID Protocol Sharing to Group Configure Virtuoso+ODS instance as an X.509 Certificate Authority and HTTPS listener Generate a Personal HTTP based Identifier for fictitious Person Entity: Tom and then bind his personal Identifier to an X.509 Certificate (thereby giving him a WebID) Generate a Personal HTTP based Identifier for fictitious Person Entity: Anna and then bind her personal Identifier to an X.509 Certificate (thereby giving her a WebID) Log into ODS-Calendar as user "Demo" (a Person Entity) Create a WebID Protocol Group, for ex. with name "MyWebIDGroup" and add the users Tom and Anna's WebID's to it: -- Tom's WebID http://cname/dataspace/person/tom#this -- Anna's WebID http://cname/dataspace/person/anna#this Share an ODS-Calendar Task / Event explicitly with "Tom and Anna" via their Group WebID: http://<cname>/dataspace/demo/group/MyWebIDGroup As user which belongs to the WebID Protocol Group "MyWebIDGroup": Tom, attempt to view the task / event shared by Person Entity "Demo" by doing the following: refresh browser access the url: -- for task: https://host:ssl-port/dataspace/username/calendar/user-calendar-instance-name/Task/task-id -- for event: https://host:ssl-port/dataspace/username/calendar/user-calendar-instance-name/Event/event-id For ex. it could be: -- for task: https://ods-qa.openlinksw.com/dataspace/demo/calendar/Demo%20User%27s%20Calendar/Task/1791 -- for event: https://ods-qa.openlinksw.com/dataspace/demo/calendar/Demo%20User%27s%20Calendar/Event/1789 when prompted by browser, select Tom's Certificate:

As user which belongs to the WebID Protocol Group "MyWebIDGroup": Anna, attempt to view the task / event shared by Person Entity "Demo" by doing the following: refresh browser access the url: -- for task: https://host:ssl-port/dataspace/username/calendar/user-calendar-instance-name/Task/task-id -- for event: https://host:ssl-port/dataspace/username/calendar/user-calendar-instance-name/Event/event-id when prompted by browser, select Anna's Certificate:

For both users after successful authentication, will be possible to view or (edit) the shared task / event:
