Start Reading


Using the specified client generated sessionId value, a shared lock is obtained for the session if the version is not currently being edited by another user or session. The shared lock prevents any other session from obtaining an exclusive lock obtained by the startEditing operation. Multiple shared locks may be obtained and held by multiple sessions. The shared lock is released using the stopReading operation.


Review the read and edit session requirements for version resource operations.
