in rdf.core: Introduce atomicity and isolation for graph manipulation
---------------------------------------------------------------------
Key: CLEREZZA-219
URL: https://issues.apache.org/jira/browse/CLEREZZA-219
Project: Clerezza
Issue Type: New Feature
Reporter: Manuel Innerhofer
It should be possible to modify a graph and commit all changes to the graph at
the same time or dismiss the modifications.
Use Case:
A POST request with form data is sent to the clerezza platform. The form-data
of the request contains the contact information of a user. The clerezza
platform starts to fill the data into the content graph. At one point the
submitted email address is check for validity and throws an
IlleagalFormatException. It is desirable that the information already added to
the graph is not commited and can be dismissed by the server code. Furthermore
the already added data should have never been visible to other processes
accessing the content graph. Only when a explicit "commit" command was executed
should the modifications be visible to other processes only
