SPARQL insert containing expression

Question

I would like to insert triple patterns like this into a Sesame endpoint, but I just can't seem to pull it all together

bind(UUID() as ?uuid) .
bind(now() as ?timeVal) .
:event1 :hasUuid ?uuid.
:event1 :hasTimestamp ?timeVal

• Virtuoso seems to have a propriety way of doing it
• It seems like a similar issue is addressed in this question
• @AKSW gave some good advice for doing something similar in a construct query

Answer 1

I'm not familiar with Sesame/RDF4J, but the following works with Jena ARQ:

INSERT
  { 
  :event1 :hasUuid ?uuid .
  :event1 :hasTimestamp ?timeVal .
  }
WHERE
  { SELECT ?uuid ?timeVal
    WHERE
      {
      BIND(UUID() AS ?uuid) .
      BIND(now() AS ?timeVal) .
      }
  }
