KOS Registry

Source files and script to aggregate information about knowledge organization schemes

This repository is used to aggregate information about knowledge organization schemes (KOS) relevant to project coli-conc. The information is aggregated from:

• YAML file kos.yml stored in this repository
• DANTE API
• Wikidata

KOS information from BARTOC will be added in a later version.

YAML file registry.yaml in this repository further contains metadata about the aggregated KOS registry.

Releases

Each commit to the master branch results in two files published as GitHub release:

• kos-registry.json contains a JSKOS Registry
• kos-registry.ndjson only contains the list of JSKOS Concept Schemes

It's possible to download the latest release files this way:

curl -s https://api.github.com/repos/gbv/kos-registry/releases/latest \
| jq -r '.assets[].browser_download_url' | xargs wget -N

Requirements

To locally aggregate you need:

• jq
• some npm modules (run npm install)
• make

Usage

Calling npm run all (or just make) will create the following files:

• kos.ndjson
• wikidata.ndjson
• dante.ndjson

It will also combine those files by merging overlapping concept schemes into the relase files. Conflicting values are ignored so information in kos.yaml has priority.

Call npm run validate to validate the files. See Makefile for individual conversion steps.
