Build SKOS taxonomies and thesauri on open standards. Glossary, editor, business view, qSKOS validation, visualizer, DCMI metadata, SPARQL and import/export, with provenance and governance.
A staging bucket for unstructured candidate terms — a garage before the taxonomy. Import a flat list, link it to a taxonomy, then promote terms into it as SKOS concepts — each one as a top concept or placed under a parent you choose. Lists can also sit unlinked until you're ready.
The natural-language box maps common questions to SPARQL you can edit. Supported: SELECT/DISTINCT, BGP, a, prefixes & IRIs, OPTIONAL, FILTER, single-predicate paths p+/p*, COUNT/SUM with GROUP BY, ORDER BY, LIMIT. Prefix : is your base namespace. Everything runs in your browser — nothing is uploaded.
Choose a file or paste below, then Import. Loads a SKOS taxonomy from RDF (Turtle, RDF/XML, JSON-LD, RDF/JSON) or a spreadsheet (CSV or Excel .xlsx). SKOS-XL labels resolve to plain labels.
Building in a spreadsheet? Download the CSV template — one row per concept; the broader column names the parent.
Download the whole taxonomy. RDF formats include Dublin Core; the spreadsheet is a flat CSV (one row per concept) that opens in Excel, Numbers or Google Sheets.
Need SKOS-XL or plain-label variants? Use the Export tab for full formatting options and a live preview.
Suggest a term for the taxonomy. A taxonomist will review it. Attach supporting resources — documents, images, spreadsheets or wiki pages — to give context.

Describe your taxonomy with Dublin Core metadata. Only the title is required — you can change any of this later in the editor.
