  3. Multiple metadata representations that enable a variety of presentations
  4. High precision Search and Find queries that simply use the metadata documents (by referencing entity URIs) as the query's Data Source Name

How Do I Discover Alternative Metadata Representations?

Description
  • The specifications described were valid prior to 1977. The primary difference between the obsolete and current tape specifications is that the pre-1977 specifications did not allow for records to be spanned. These specifications became obsolete when the new specifications were adopted by MARC 21 users at the end of 1977. The tape format and labeling described are based on those specified in American National Standard Magnetic Tape Labels for Information Interchange (ANSI X3.27-1969).
