RefDB is a reference database and bibliography tool for SGML, XML, and LaTeX documents. Command-line tools allow interactive or scriptable access to the data which are stored in a SQL database. RefDB can also be accessed through a Web interface, a SRU interface, or via editor extensions (Emacs/vim). Libraries for Perl and PHP are available for programmers. RefDB provides sophisticated character encoding handling, using Unicode by default.
Jade Tex is a TeX macro package for processing the output from Jade/OpenJade in TeX (-t) mode. It is part of the standard DSSSL Jade-based toolchain to produce PostScript or PDF from SGML/XML documents. It produces output either as a DVI file, or directly to PDF when using pdfjadetex.
AlcoveBook DTD and stylesheets is a strict subset of the DocBook DTD. The ultimate goal is to provide a series of DTDs for enterprise use, commercial proposal, whitepaper, etc. For now, this is one single SGML DTD. The stylesheets are usable with both DocBook and AlcoveBook. They include a set of extensions over Norman Walsh's modular docbook stylesheets (docbook-dsssl), and a book- like layout for articles.
