Purpose: An ad hoc report, to be run on demand. Check, if values were entered syntactically correct., e.g.: URL (MARC 856), name space for URN, DOI, Handle etc.
This task could instead be solved as a build in control feature when editing a record in Inventory. A check, when saving the created Instance record. The check for values being entered syntactically correct, would generate a warning message/an error message, and prevent that a record could be saved, if these data was not correct entered in the Instance record. MARCcat probably has similar control features (Charlotte will follow up with Tiziana)
