SPARQL UPDATE

Some times you may find the need to update your flow graph. This can be done with the Flow Manager Modify API. Modifications come in the form of INSERT or DELETE queries.

For example, if we previously added an Unidentified author to a flow, we may want to replace them with a named author. We may know exactly what we want to change and so fully define the triples to change:

INSERT DATA 
{ 
  <urn:absolute:flows#flow--41e0cd93-6fb2-4786-94ab-5adec21960cc> <https://attackflow.space/attack-flow#author> <urn:absolute:flows#person--4c49da73> .
  <urn:absolute:flows#person--4c49da73> a <http://xmlns.com/foaf/0.1/Person>, owl:NamedIndividual;
      <http://xmlns.com/foaf/0.1/firstName> "Gabriel";
      <http://xmlns.com/foaf/0.1/family_name> "Bassett";
      <http://xmlns.com/foaf/0.1/workplaceHomepage> "http://infosecanalytics.com" .
}

and

DELETE WHERE 
{ 
  <urn:absolute:flows#flow--41e0cd93-6fb2-4786-94ab-5adec21960cc> <https://attackflow.space/attack-flow#author> <urn:absolute:flows#Unspecified> .
}

But in many cases, you’ll want to replace it in a more general way, using variables. Note, we’re going to change the ‘INSERT DATA’ to ‘INSERT’ since we’re using variables.

DELETE {
      ?flow <https://attackflow.space/attack-flow#author> <urn:absolute:flows#Unspecified> .
}
INSERT { 
  ?flow <https://attackflow.space/attack-flow#author> <urn:absolute:flows#person--4c49da73> .
}
WHERE {
      ?flow <https://attackflow.space/attack-flow#author> <urn:absolute:flows#Unspecified> .

}
