A. Soroka,
The syntactical form of my user id values, is a variable containing "U0000001"
through "U9999999" - the user id is assigned when an end-user first logs on to
the system, with their e-mail and password - as long as the account is valid,
the end-user retains the same user id assigned to it when they first logged on
(registered)...
I still need to know how to generate the Named Graph based on IRI, etc?
Thank you,
Al
