v1.0.0

v1.0.0 — Initial Release

Spec-complete OBO 1.4 format parser for TypeScript and JavaScript. The first and only OBO parser in the npm ecosystem.

Features

• Two APIs — synchronous parseObo(string) for small files, async parseOboStream(stream) for large ontologies
• Full OBO 1.4 coverage — all stanza types ([Term], [Typedef], [Instance]), all tags, qualifier blocks, escape sequences, multi-line values
• Fully typed — every OBO construct has a corresponding TypeScript interface with JSDoc
• Zero runtime dependencies
• ESM and CommonJS dual-package output
• Node.js 18+ and modern browsers

Spec coverage

• 20 header tags including treat-xrefs-as-* macros, subsetdef, synonymtypedef, idspace, owl-axioms, property_value
• 24 Term tags, all Typedef relationship properties, Instance tags
• Escape sequences: \", \\, \n, \t, \:, \!, \xHH
• Qualifier blocks on is_a, relationship, intersection_of, union_of, equivalent_to, disjoint_from
• UTF-8 BOM stripping, CRLF handling, continuation lines

Tested against

• Gene Ontology (48,291 terms)
• Plant Ontology (1,793 terms)
• PATO (2,785 terms)
• Units of Measurement Ontology (574 terms)

All parsed with zero unparsed tags and full string/stream API parity.
