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. ### Sources - - - - source_facts.executables - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** open-sp - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [gettext](https://www.automicvault.com/pkg/brew/gettext/) - Runtime dependency declared by Homebrew. - [autoconf](https://www.automicvault.com/pkg/brew/autoconf/) - Build dependency declared by Homebrew. - [automake](https://www.automicvault.com/pkg/brew/automake/) - Build dependency declared by Homebrew. - [docbook](https://www.automicvault.com/pkg/brew/docbook/) - Build dependency declared by Homebrew. - [ghostscript](https://www.automicvault.com/pkg/brew/ghostscript/) - Build dependency declared by Homebrew. - [libofx](https://www.automicvault.com/pkg/brew/libofx/) - Popular package that depends on this formula. - [python-markdown](https://www.automicvault.com/pkg/brew/python-markdown/) - Shares av.db curated category or tags: cli, developer-tools, markup, parser. - [comrak](https://www.automicvault.com/pkg/brew/comrak/) - Shares av.db curated category or tags: cli, developer-tools, markup, parser. - [discount](https://www.automicvault.com/pkg/brew/discount/) - Shares av.db curated category or tags: cli, developer-tools, markup. - [hoedown](https://www.automicvault.com/pkg/brew/hoedown/) - Shares av.db curated category or tags: cli, developer-tools, markup, parser. - [html-xml-utils](https://www.automicvault.com/pkg/brew/html-xml-utils/) - Shares av.db curated category or tags: cli, developer-tools, markup. - [htmlcleaner](https://www.automicvault.com/pkg/brew/htmlcleaner/) - Shares av.db curated category or tags: cli, developer-tools, markup, parser. - [htmlcxx](https://www.automicvault.com/pkg/brew/htmlcxx/) - Shares av.db curated category or tags: cli, developer-tools, markup, parser. - [markdown](https://www.automicvault.com/pkg/brew/markdown/) - Shares av.db curated category or tags: cli, developer-tools, markup. - [peg-markdown](https://www.automicvault.com/pkg/brew/peg-markdown/) - Local package facts share a topical domain.
