Could I ask for a little clarification or confirmation/denial of my initial guesses? Specifically,
* what are "tags"? MARC/UNIMARC/MARC21 fields? e.g.: mandatory "tags" empty
"fields" or "field identifiers" will work, depending on whether you are talking about the tag itself or the data identified by the tag. Here's the Library of Congress' description (from http://www.loc.gov/marc/96principl.html): 6. Variable Fields and Tags 6.1. The data in a MARC record is organized into fields, each identified by a three-character tag. 6.2. According to ANSI Z39.2, the tag must consist of alphabetic or numeric ASCII graphic characters, i.e., decimal integers 0-9 or letters A-Z (uppercase or lowercase, but not both). The MARC 21 formats have used only numeric tags. 6.3. The tag is stored in the directory entry for the field, not in the field itself. -- Stephen Hedges Skemotah Solutions, USA www.skemotah.com -- shedges@skemotah.com
