NEN Knowledge Organization System

The NEN Knowledge Organization System describes a data model for standardisation bodies based on SKOS. It consists of:

• the International Classification for Standards,
• a catalog with standard documents,
• and a controlled vocabulary with terms and definitions.

It aims to create a datamodel for normalized terms and definitions that can be easily published using Skosmos.

Publishing terms and definitions as Linked Open Data

Below we list a number of resources to help other standard bodies publish their terms and definitions as Linked Open Data.

Dataflow

The following diagram is a visual representation of how information flows through the system.

Workflow automation and tooling

The following open source projects can execute and automate parts based of the workflow.

• Excel2RDF: Convert an Excel template to RDF
• XML2CSV: Extract terms and definitions from XML using the NISO STS
• Github Actions: Automate, customize, and execute your workflows in your repository
• Skosmos: View terms using an open source web-based SKOS browser and publishing tool

Example

Examples from the NEN.

• NEN Thesaurus: Search terms and definitions in the browser.
• NEN controlled vocabulary: View the controlled vocabulary in RDF.
