ODS AddressBook? 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-AddressBook? 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-AddressBook contact 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 contact shared by Person Entity "Demo" by doing the following:
- refresh browser
- access the url:
```
https://host:ssl-port/dataspace/username/addressbook/user-addressbook-instance-name/contact-id
```
  - For this example, it should be:
```
https://localhost:4433/dataspace/demo/addressbook/Demo%20User%27s%20AddressBook/1003
```
- when prompted by browser, select Tom's Certificate
As user which belongs to the WebID? Protocol Group "MyWebIDGroup?": Anna, attempt to view the contact shared by Person Entity "Demo" by doing the following:
- refresh browser
- access the url:
```
https://host:ssl-port/dataspace/username/addressbook/user-addressbook-instance-name/contact-id
```
  - For this example, it should be:
```
https://localhost:4433/dataspace/demo/addressbook/Demo%20User%27s%20AddressBook/1003
```
- when prompted by browser, select Anna's Certificate
For both users after successful authentication, will be possible to view or (edit) the shared contact:
