VocPrez

  • What it is — VocPrez is an archived, read-only web delivery system for RDF vocabularies formulated in SKOS. It presents vocabulary data over HTTP as human-readable pages and machine-readable representations, and the project says its functionality is now incorporated into Prez.

  • Key concepts —

    • VocPrez treats a SKOS ConceptScheme as synonymous with a vocabulary and ships presentation support for SKOS ConceptScheme, Collection, and Concept, plus registers/containers of those resources.
    • It distinguishes an information-model view, defined by a formal profile, from the media format used to serialize that view; multiple profiles and multiple media types per profile are supported.
    • Its pyLDAPI foundation turns RDF data into Linked Data, exposing the same vocabulary material in human- and machine-readable forms.

  • How you’d use it — Configure one or more vocabulary sources and instance details, then serve the Python/Flask WSGI application (the root README gives gunicorn wsgi:application for local use). Documented back ends include RDF databases/triplestores through SPARQL, local RDF files, Research Vocabularies Australia, VocBench3, vocabulary APIs, and GitHub; adapters populate a cached vocabulary index. Jinja2 templates produce HTML for SKOS objects, while mapping code provides RDF or other machine-readable formats, and deployments can override templates for institutional branding.

  • LLM angle — none stated

  • Pitfalls & lessons —

    • The repository is archived and directs users to Prez, where VocPrez has been incorporated.
    • VocPrez is a publisher, not a SKOS editor; it expects an existing configured data source.
    • It is ready for SKOS-only vocabularies; SKOS-plus-extra features require a fork or enhancement.
    • Release 2.4 changed configuration incompatibly by replacing CACHE_DIR with a required CACHE_FILE, and the 1.0 release is explicitly unsupported.

  • Verdict — A focused SKOS-to-Linked-Data publishing interface with profile-aware HTML/RDF delivery, useful as documented precedent but superseded by Prez.
