How are bibliographic data files created using the MARC Import Utility wizard?
When a record loading report that adds records to the catalog is used, such as the Load Bibliographic Records report, a copy of the bibliographic records is written in the /Unicorn/Marcimport directory on the SirsiDynix Symphony server. This copy of records is called the bibliographic data backup file.
Although the original imported file is no longer available after bibliographic records have been loaded, the MARC records are stored in one of two directories on the server. Records that were successfully loaded into the catalog or successfully loaded for review are stored in the /Unicorn/Marcimport/Bibbackup directory. Records that failed to load are stored in the /Unicorn/Marcimport/Biberror directory.
The records that were successfully loaded into the catalog or successfully loaded for review can be copied back into the /Unicorn/Marcimport directory to be available for loading again.
All bibliographic data backup files are saved as part of the daily backup. In the event of a system failure, all of the report-loaded records will be present on the daily bibliographic data backup. The records may easily be reloaded when the system is operational.
The bibliographic data backup files display on the Loaded Bib Files tab of the MARC Import Utility wizard. Bibliographic data backup files use the following naming convention.
[date and time][library number][session number][n|r|e]
The first ten digits represent the date of the record load, in YYMMDDHHMM format. The next four digits represent the library number from the policies. The last one or two digits represent the session number from the given date. The final alphabetic character indicates the file type. The file type may be one of the following.
| • | An n indicates new records that were loaded into the catalog. Files with the n file type are listed in the Loaded Bib Files tab in the MARC Import Utility wizard. |
| • | An r indicates review records that were loaded into the review file. Files with the r file type are listed in the Loaded Bib Files tab in the MARC Import Utility wizard. |
| • | An e indicates error files that were not loaded. Files with the e file type are listed in the Bib Error Files tab in the MARC Import Utility wizard. See the FAQ ”How can I identify files that were not successfully imported with the MARC Import Utility wizard” in this topic for more information. |
For example the following backup file name illustrates the naming convention.
040118125700306n
In the above example, the date and time are January 18, 2004 at 12:57 p.m. The library number from the policies is 0030. The session number shows that this file was the sixth file loaded on that date. The n file extension indicates that new records were loaded into the catalog.
How do bibliographic data files display in the MARC Import Utility wizard output?
The MARC Import Utility wizard output displays the MARC record data numerically. The header for each record includes the size=, last=, and #tags=, which all contain byte counts used to make sure the record data is accurate. The label ”num=” is equivalent to the MARC tag number. The indicators in the data are not separated, and immediately precede the text in the data fields. Everything else is a count of data and the position of that data in the MARC record.
How can I identify files that were not successfully imported with the MARC Import Utility wizard?
The Bib Error Files tab in the MARC Import Utility wizard lists files that were not successfully imported. Bibliographic load error files are automatically created when a record loading report, such as the Load Bibliographic Records report, is used. The original imported file is no longer available after it has been loaded, but the MARC records that produced errors in the log of the report are saved in the /Unicorn/Marcimport/Biberror directory and can be copied back into the /Marcimport directory to be available for loading again.
All bibliographic load error files use the following naming convention.
[date and time][library number][session number]e
The first ten digits represent the date of the record load, in YYMMDDHHMM format. The next four digits represent the library number from the policies. The last one or two digits represent the session number from the given date. The e final alphabetic character indicates error files that were not loaded.
For example, the following error file name illustrates the naming convention.
040118125700306e
In the above example, the date and time are January 18, 2004 at 12:57 p.m. The library number from the policies is 0030. The session number shows that this file was the sixth file loaded on that date. The e file extension indicates that records were not loaded successfully into the catalog because of errors.
