Batch Processing from a MARC21 Data File

Overview

Batch processing allows the data from a MARC21 export report file to create METS files. The processor will step through each record within the report, and generate a METS file for each per your specifications in the metadata preferences section.

Process Instructions

Selecting the second option ( Convert a MARC21 file to METS ) from the Batching Menu will launch the form:

Select the input MARC21 file to use.

Next, you are given the opportunity to enter up to eight constants from the second tab under step 2. Finally, select the destination folder for all the resulting METS files.

You will also need to enter a value for the first bibid to be used as the ObjectID in the resulting METS files. The value you enter must adhere to the SobekCM BibID rules.

SobekCM Bibliographic Identifier (BibID) Rules

The BibID is a ten digit alphanumeric identifier used for SobekCM libraries which begins with at least two characters and ends with at least four numbers. Whatever you enter will be the beginning of the final BibID's, which also act as part of the ObjectID for the METS files.

If you enter a string less than 10 characters long, this will be the prefix. For example, entering 'ca008' will cause the first BibID assigned to be 'CA00800000', the second 'CA00800001', the third 'CA00800002', etc..

Entering a full BibID, such as 'MANIOC0123' will break the item into two parts and compute each BibID from the provided BibID. For example, entering 'MANIOC0123' will cause the first BibID assigned to be 'MANIOC0123', the second 'MANIOC0124', the third MANIOC0125', etc..

Press the EXECUTE button once you are ready to proceed.

Process Description

Once the process is initiated, the processor will step through each record in your input file and perform the following steps:

  1. Read the next record from the MARC21 report
  2. Input this data into a new METS object
  3. Apply all the constants from the processor form
  4. If no source institution code or source institution statement was included yet, the defaults from your metadata preferences are applied.
  5. METS file is written to your destination folder

Once complete, some very simple information will be displayed in the results form, including the newly assigned Bibliographic Identifier (BibID) and Volume ID (VID) which combine to form the METS ObjectID's.
