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 On Thursday, July 7, 2016 6:25 AM, A.
