history
Project history and usage
OpenSP is the OpenJade project's SGML/XML parsing toolkit, descended from James Clark's SP suite.
Project history
The OpenJade distribution page says OpenJade was undertaken by the DSSSL community to maintain and extend James Clark's Jade and the related SP suite of SGML/XML processing tools. The same page lists OpenSP 1.5.1 as the latest stable OpenSP release.
The official SVN page documents the OpenSP source-control subtree under the OpenJade Subversion repository.
Adoption history
The supplied package metadata records a Homebrew package. OpenSP's practical adoption is in SGML/XML validation, normalization, catalog, and legacy documentation workflows.
How it is used
The packaged command set includes onsgmls, osx, osgmlnorm, ospam, ospcat, and ospent for validating, normalizing, cataloging, and converting SGML-oriented documents.
Why package nerds care
OpenSP is package-nerd significant because it is old documentation infrastructure: obscure command names, SGML catalogs, public identifiers, normalization, entity handling, and validation still matter in legacy publishing stacks.
Timeline
- 2002: OpenSP 1.5 release-era documentation was produced by the OpenJade project.
- 2005: the official download page identifies OpenSP 1.5.1 as the latest stable release.
- 2000s: the official project documented migration to Subversion for OpenJade and OpenSP source control.
Related projects
- Related projects include OpenJade, James Clark's Jade, James Clark's SP, DSSSL, SGML, XML, and DocBook-style documentation toolchains.
