"We wanted to create the best archive we could," says Thomas Mastre, HSDL project manager, "with a wide range of documents that could be augmented continually." Most of the students participate in the program via distance learning, so the library also needed to be Web-based to provide for access from the learner's location.
An initial taxonomy was set up in fall 2003 when material for the HSDL was being placed in three different repositories, and as a "living" taxonomy, it has developed over time.
After considering a number of options, the HSDL Project Team selected Teragram (tera gram.com), which produces a number of language processing tools.
"One of our requirements was for a classification system that could evolve," says Tom Mastre, project manager for the HSDL. "Every week we add about 200 to 300 new documents, and sometimes we need to add new categories, which we can do with Teragram." In addition, categories that have grown too large may need to be broken down into sub-topics and retagged, which is another available option.
The value of the HSDL goes well beyond the academic program that was the catalyst for its development.
The Autoweb System also pioneers automatic site generation from abstract, language-independent presentation specifications, whereas other comparable tools are based on imperative programming (HSDL
, OOHDM) or language-dependent page templates (RMC, HyperG, Strudel, Araneus).
Infinova of Monmouth Junction, New Jersey, has introduced the V2413 multi-protocol PTZ Data Merger & Code Distributor that accepts high-speed data line (HSDL
), RS-232, or RS-485 information from the company's matrix switchers and controllers.
