The AFLCAITI Standards Project is testing the Military Standard for the Automated Interchange of Technical Information, MIL-STD-1840 the Standard. The objective of the tests is to demonstrate the validity of the transfer protocol defined in the Standard itself and the viability of standardized formats for the transfer of technical information defined in other specifications used by the Standard. Two documents file sets were prepared by Pratt and Whitney for this test. The documents were prepared in accordance with Appendix A of the December 12, 1986 version of the Standard. The file sets, on magnetic tape, were delivered to the ATOS laboratory facility at SYSCON Corporation, San Diego, California for testing. Each file set consisted of a declaration file, SGML tagged text files, IGES illustration files, and a raster image in CCITF group 4 format written on magnetic tape in accordance with F1PS PUB 75 and the Standard. The tape format was in complete accordance with FIPS PUB 75. This critical point in the transfer process was successful. Almost any failure here would mean complete failure of the transmission. The declaration files were also completely acceptable. The text files were less successful in meeting the requirements of the USAF SGML tagging scheme. The quality could be characterized as good for a first effort but not good enough for a production environment. After making a number of simple corrections, reasonable reproduction of the original could be generated. Inexperience and lack of automated quality control AQC tools account for the errors. Figure 1 shows the result of inadequate SGML coding of the tables.
