ODS Briefcase 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-Briefcase 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-Briefcase hosted resource explicitly with "Tom and Anna" via their Group WebID: http://<cname>/webdav/webaccess/demo#MyWebIDGroup As user which belongs to the WebID Protocol Group "MyWebIDGroup": Tom, attempt to view the resource shared by Person Entity "Demo" by doing the following: refresh browser access the url: https://host:ssl-port/DAV/home/user-name/user-resource. For this example, it should be: https://localhost:4433/DAV/home/demo/kidehen.vcf when prompted by browser, select Tom's Certificate

after successful authentication, you will be able to save or view the shared resource: kidehen.vcf.
