Mandatory; Fixed length; Not repeatable. This is the date the originating system completed the compilation of the file of records. This is not the date of the creation of the records contained in the bibliographic file. The field is recorded according to Representation for Calendar Date and Ordinal Date for Information Interchange (ANSI X3.30) and Representations of Local Time of the Day for Information Interchange (ANSI X3.43). The date requires 8 numeric characters in the pattern yyyymmdd (4 for the year, 2 for the month, and 2 for the day; right justified and zero filled). The time requires 8 numeric characters in the pattern hhmmss.f (2 for the hour, 2 for the minute, 2 for the second, and 2 for a decimal fraction of the second, including the decimal point). The 24-hour clock is used. RBF Number of records in file. Mandatory; Variable length; Non-repeatable. This element includes the number of logical records contained in the file of USMARC records. DSN Data Set Name. Mandatory; Variable length; Not repeatable. The filename of the file of USMARC records (which is sent separately) for which this is a file label. ORS Originating system ID. Mandatory; Variable length; Not repeatable. The name of the system that compiled the files of records. This could be a symbol (e.g., OCLC or NUC) or text. DTS Date sent. Optional; Fixed length; Not repeatable. This is the date of transmission of the file of USMARC records. The field is recorded according to Representation for Calendar Date and Ordinal Date for Information Interchange (ANSI X3.30) and Representations of Local Time of the Day for Information Interchange (ANSI X3.43). The date requires 8 numeric characters in the pattern yyyymmdd (4 for the year, 2 for the month, and 2 for the day; right justified and zero filled). The time requires 8 numeric characters in the pattern hhmmss.f (2 for the hour, 2 for the minute, 2 for the second, and 2 for a decimal fraction of the second, including the decimal point). The 24-hour clock is used. DTR Dates of records. Optional; Fixed length; Not repeatable. This includes inclusive dates of last transaction of the records in the file, i.e. the first and last date recorded in the 005 fields of the file of records. The field is recorded according to Representation for Calendar Date and Ordinal Date for Information Interchange (ANSI X3.30). The date requires 16 numeric characters in the pattern yyyymmddyyymmdd (4 for the year, 2 for the month, and 2 for the day for each date; right justified and zero filled). FOR Format. Optional; Fixed length; Not repeatable. This element designates the format of the records, generally M for MARC. Other codes may be defined as needed (e.g., Z for Z39.2 for copyright records. DES Description of records. Optional; Variable length; Repeatable. This element describes the records. The data could be coded or describe a product name. (For example, OCLC uses B for Bibliographic describing a data type; CDS may use a product name, such as MDS-Books All.) VOL Volume. Optional; Variable length; Repeatable. This may be used if it is desirable to assign a volume number when distribution of records is by subscription. Each file within a subscription year may be given a volume and issue number. ISS Issue. Optional; Variable length; Repeatable. This may be used if it is desirable to assign a volume and issue number when distribution of records is by subscription. Each file within a subscription year may be given a volume and issue number. It may be combined with Volume (e.g., V1402). REP Reply to. Optional; Variable length; Repeatable. This field contains an address given as a contact for problems/questions in transmission. It may include an Internet or postal address. NOT Note. Optional; Variable length; Repeatable. This field contains textual information or messages about the file. Order of fields: The order of fields is as specified in the above list. Mandatory fields will come first and within that fixed length first, then the remaining variable fields. Length of fields: Fixed fields have a specified length. Variable fields have no maximum length. Field tags: Each field begins with a three-character tag followed by two blank spaces (ASCII 20). End of field marker: Each field ends with the end-of-field marker (ASCII 1E) immediately following the data in the field. Transmission of file label: File label is to be transmitted as a separate file in ASCII format at the same time as the file of records. Institutions (recipient and sender) may work out archiving the file label and the file of records.
