org.apache.marmotta.kiwi.persistence.KiWiConnection.storeNode()
Store a new node in the database. The method will retrieve a new database id for the node and update the passed object. Afterwards, the node data will be inserted into the database using appropriate INSERT statements. The caller must make sure the connection is committed and closed properly.
If the node already has an ID, the method will do nothing (assuming that it is already persistent) @param node @param batch @throws SQLException
