MIL-HDBK-9660 Dod Produced Cd-Rom ProductsThis document was prepared by the Defense information Systems Agency DISA, in cooperation with the services and other activities within the Department of Defense DOD. The goal of this document is to provide information and guidelines to support the creation and interoperability of Compact Disc-Read Only Memory CD-ROM development and use within DOD. This document specifies core compact disc fundamentals for the DOD community. It is strongly recommended all DOD components comply with the fundamentals established within this document. Specialized functions within DOD may require expanded internal guidance to meet their own mission needs. All other Government entities are invited to use this document.

MIL-HDBK-9660B

4.4  Disc Contents.

4.4.1  Volume and File Structure.  ISO 9660:1988, Information Processing - Volume and File Structure of CD-ROM for Information Interchange, is the volume and file structure for DOD-produced CD- ROMs.

4.4.2  Internal CONTENT.TXT File.  For every DOD-produced CD-ROM disc, include a flat ASCII file titled "CONTENT.TXT" in the top level (root) directory with the following format and information:

a.  Eighty or less characters per line, with a hard return (ASCII Carriage Return - Line Feed combination CRLF) at the end of each line.  Use descriptors (such as "TITLE:") to introduce each new information block in all capital letters, beginning in column one of the line.  Use upper and lower case for associated data.

b.  Following is the proper structure for the CONTENT.TXT file.  Descriptor headings that should appear in the CONTENT.TXT file are shown in bold type.  For consistency, use all the descriptors, although the associated information is optional.  To improve readability, if a descriptor requires more than one line, indent all lines after the first by eight spaces

TITLE:

State verbatim the name by which the disc is known, including any disc set numbering schemes, such as

1 of 3.  Do not include any superfluous descriptions or qualifiers. More than one title may be needed if the CD contains more than one distinct product or contains sets of information (See DOCUMENT IDENTIFICATION:).

EDITION:

The edition, version, revision, change number or identification  of the title.

VOLUME IDENTIFICATION:

This should be identical to the eleven characters of the Volume Identifier (first eleven characters of the ISO 9660 Volume Identifier (32 characters available)) written in the header of the disc. Use only upper- case letters, 0-9, and the underscore for Volume Identifications.  One way to accommodate the requirements for unique volume identification for discs in CD-ROM jukeboxes, towers, and network systems is to use the producing organization's Unit Identification Code (UIC) as the first six characters; the producing organization should then manage/ensure disc uniqueness using the next five characters of the Volume Identifier.

ORIGINATOR:

The name of an organization(s) or individual(s) that developed the information (see definition of contributed by).  If the names of editors or compilers are provided, follow each name by "(ed.)" or "(comp.)," respectively.

CD PUBLICATION DATE:

The date when the disc was published or otherwise made available for release.

SECURITY CLASSIFICATION:

Name of the security restrictions on the disc.  Use the highest classification of any information on the disc.
