SRU Record Update - frequently asked questions (FAQ) / Troubleshooting
What is the difference between SRU and SRU Record Update?
An SRU Record Update allows data records to be entered, changed and deleted in the GND, i.e. it provides write access. The SRU Interface by contrast, offers read-only access..
How can I test the SRU Record Update Interface?
In which formats can new or changed data records be entered?
In which field is the time stamp given in MARC21-xml format?
The time stamp is inserted in MARC-21-xml-field 005 and is used for comparison with the current time stamp of the data record in the database.
What is the the "recordIdentifier" with gnd-prefix in the SRU response?
The "recordIdentifier" is the unique GND number. It commences with the "gnd" namespace followed by the GND number in the form: "gnd:gnd118512676".
Explanation: The GND number is given in MARC field 035 $a, e.g. 035 $a(DE-588)118512676.
The ISIL/MARC Org. Code "DE-588" is resolved as the prefix "gnd" for the "recordIdentifier". See also German ISIL- and Library Codes Agency.
What is the "recordIdentifier" with ppn-prefix in the SRU response?
The "recordIdentifier" is the internal identification number of the DNB. It commences with the "ppn" namespace followed by the identification number in the form: "ppn:118512676".
Explanation: The PPN/IDN is given e.g. in MARC-field 001, e.g.. 129602434.
The interface has a general orientation, meaning that the SRU response always contains the internal identification number of the DNB - regardless of which identifier was sent in the SRU request.
