history

Project history and usage

Jing-Trang packages two long-lived Java tools from the RELAX NG ecosystem: Jing, a RELAX NG validator, and Trang, a multi-format XML schema converter. Together they cover validation, conversion between RELAX NG XML syntax, RELAX NG compact syntax, XML DTDs, and W3C XML Schema output, and schema inference from example XML documents.

Project history

Jing and Trang grew out of James Clark's RELAX NG work. The RELAX NG home page identifies Jing as a Java validator written by James Clark and Trang as a Java schema converter written by James Clark that uses Jing. RELAX NG itself was standardized through OASIS in 2001, gained compact syntax in 2002, and became part of ISO/IEC 19757.

The project history spans early 2000s RELAX NG tooling, a Google Code era, and the GitHub-hosted `relaxng/jing-trang` repository. The preserved Jing and Trang pages state that development of both tools took place together in the jing-trang project, while the GitHub repository preserves the combined build and produces `jing.jar` and `trang.jar`.

Adoption history

Jing became one of the canonical open-source RELAX NG validators listed by relaxng.org, with support for both XML and compact syntaxes and library use with SAX2 parsers. Trang earned a similar role for schema conversion, especially for teams maintaining DTD, RELAX NG compact syntax, and W3C XML Schema artifacts across XML publishing and standards workflows.

How it is used

Package-manager users mainly install Jing-Trang to get the `jing` and `trang` commands. `jing` validates XML documents against RELAX NG schemas, while `trang` converts schemas among supported formats and can infer a schema from example XML. The repository README documents building the Java jars with the included Ant wrapper.

Why package nerds care

Jing-Trang matters because it is the kind of old, stable XML infrastructure package that quietly supports documentation toolchains, standards validation, editors, and build systems. Its version tags and release names preserve the older date-stamped style common in Java XML tools, and its presence in Homebrew, Debian-family packages, Nix, and Maven metadata reflects a tool that survived long after XML schema debates cooled.

Timeline

  • 2001: RELAX NG became an OASIS Committee Specification, and early jing-trang tags include the RELAX NG tooling era.
  • 2002: RELAX NG Compact Syntax reached OASIS Committee Specification status; Trang's page documents compact-syntax conversion support.
  • 2003: RELAX NG became ISO/IEC 19757-2, making Jing useful for validating an international-standard schema language.
  • 2009: The V20091111 tag and Maven metadata show the Google Code-era combined Jing/Trang artifact.
  • 2015: V20151127 appeared in the GitHub repository's release history.
  • 2024: V20241231 continued the combined GitHub-hosted release series.

Related projects

  • Jing-Trang is tied to RELAX NG, TREX, RELAX Core, DTDinst, SAX2, W3C XML Schema, and XML editor integrations. The RELAX NG software list places it beside validators such as RNV, libxml2, MSV, and schema-related tools such as rnc2rng and RNGOM.
