MARC 21 to ISNI XML mapping
Source documents
ISNI XML request schema - this includes MARC and PICA equivalents for the schema elements in the images.
ISNI database fields consolidated file provides a linear list of the major database fields and their M21 equivalents.
ISNI data element values includes the value lists for the fields that have defined values.
Mapping examples (for demonstration only):
| MARC 21 | XML root element | Processing notes |
|---|---|---|
| 100 $a | surname | If first indicator is 1, take data preceding comma, if first indicator is 0 or 3 take all the data |
| 100 $a | forename | If first indicator is 1, take data after comma |
| 375 $a | gender | check data element values to see if values need to be adjusted. In this case, no. |
| 377 $a | languageOfIdentity | check values – need to be ISO 3 characters |
Once this table has been completed, the root elements need to be inserted into the request tree structure and default values given for schema root elements that cannot be filled from the M21 data.
