NAME

skos2jskos - convert SKOS/RDF to JSKOS

SYNOPSIS

  skos2jskos OPTIONS [ FILES | URL ]

USAGE

This script can be used to convert SKOS data from local RDF files, URL, or SPARQL-endpoint to JSKOS format (SKOS in JSON-LD). The script is aligned with JSKOS 0.4.4 but it does not cover all possible fields yet.

On success the following files are created in normalized JSON:

scheme.json

JSKOS description of the concept scheme

concepts.ndjson

JKSOS description of all concepts

Location of the files can be controlled with option --directory and option --name can be used to prepend a prefix to each file.

Conversion is not optimized for speed so be patient!

SKOS requirements

The concept scheme MUST have a title (dct:title).

All concepts MUST be linked from the concept scheme via skos:inScheme.

OPTIONS
