...Gateway

Trade names and company products are mentioned in the text in order to adequately specify experimental procedures and equipment used. In no case does this identification imply recommendations or endorsements by the National Institute of Standards and Technology, nor does it imply that the products are necessarily the best available for the purpose.

Development of the APIB and the APIB gateway is funded by the National Institute of Standards and Technology's Systems Integration for Manufacturing Applications (SIMA) program, a part of the US government's High Performance Computing and Communications initiative.

...scripts

World Wide Web gateways often use HTML forms in this way as a means of obtaining input for CGI programs.

...HREF="node4.html#FIGENTITY">6)

Note that the references to Figure 7 and clause 6.3.3 in the NOTES are currently hard coded in the raw SGML used to generate this web page (see Figure 10). Although the IR DTD supports cross references, the IRs in the APIB do not currently take advantage of this support. These IRs will be re-tagged in the near future to use the DTD's constructs for cross referencing.

...node

If the web browser caches previously viewed web pages, users can achieve the same effect by using their web browser's backtracking mechanism. They will achieve a faster response because the APIB will not be queried. However, if the APIB has recently been modified, the previously viewed web pages will be out of date. Also, if the user obtained the current web page by choosing a name from a list of IR Query results, then there are no cached pages to backtrack to, and the user has no choice but to use the backtracking push buttons.

...command

This would be improved if users could review the SGML, leave a pointer to it, and invoke a copy at AP publication time. This would require maintaining a table of pointers on the APIB server for each user. These tables could be maintained in a manner similar to the method the NIST EXPRESS Server[LIBES94] (see Section 6) uses to maintain users' private directories.

...invoked

Actually, there are four CGI script names who share the same Tcl file by means of symbolic linking. Tcl code at the beginning of the file derives expitem from the value of argv[0]. Also, there are some additional implementation details that have been omitted from this discussion.

Although standards bodies such as ISO and ANSI may have elaborate publishing systems, they are often unavailable to those who actually write the standards.

This involves using natural language understanding techniques from artificial intelligence to semantically analyze the texts in the digital library and to analyze queries.

...DTD

The legacy IRs and APs were written using either commercial word processing tools or LaTeX[LAMP]. An auto-tagging software tool has been implemented to help convert the LaTeX IRs into SGML, but this tool assumes that the IR document uses a particular set of LaTeX style files developed for STEP[WILSON]. Unfortunately, some of the legacy LaTeX IRs use LaTeX customizations that are incompatible with the auto-tagger.
