Unleash the full potential of controlled vocabularies.

SkoHub enables easy management and publication of SKOS vocabularies, widely used in knowledge organization systems across libraries, archives, and educational institutions. By leveraging our tools, users can quickly transform their vocabularies into machine- and human-readable formats using Git-based workflows.

Key Features

  • Git-based workflows: Utilize Git for editorial control, ensuring content is current and accurate.
  • Human- and machine-readability: Access vocabularies in formats understandable by both humans and software.
  • Serverless setup: Run SkoHub without dedicated server infrastructure.

Repositories

SkoHub Vocabs

SkoHub Vocabs is a static site generator for Simple Knowledge Organization Systems

Code

Status: Stable Beta

This part of the project covers the need to easily publish a controlled vocabulary as a SKOS file, with a basic lookup API and a nice HTML view including links to an inbox for each subject (example). Also, each subject is exposed as an ActivityPub actor in order to be used with SkoHub Pubsub. For details, see the blog post.

SkoHub Pages

The easiest way of publishing SKOS vocabularies

Code

Status: Stable Beta

An example repository that you can fork to publish your SKOS vocabularies using GitHub infrastructure (Actions and Pages). For details, see the blog post.

SkoHub Reconcile

Use your SKOS vocabularies in reconciliation services

Code

Status: Beta

SkoHub Reconcile provides an API conforming to the Reconciliation API specification. V2 and the current draft are supported. To upload your vocabularies use the SkoHub Reconcile Publish module. Try it out on our SkoHub Reconcile test server.

SkoHub Shapes

Validate your SKOS vocabularies with SHACL

Code

Status: Beta

To validate your SKOS vocabularies we developed a set of SHACL shapes. Currently we have a basic SKOS shape that checks against the class and property definitions defined in the SKOS Reference and a slightly stricter SkoHub Shape that has some SkoHub specific constraints.
