lex-dk

name	lex-dk
description	lex.dk — Denmark's national encyclopedia (~245 k articles). A drop-in Wikipedia replacement for Danish encyclopedic knowledge. Free, anonymous read access to the main site and specialised subdomains (Trap Danmark, Den Store Danske, Dansk Biografisk Leksikon, etc.). Use for authoritative Danish-language facts, citations, or encyclopedic lookups — reach for it instead of Wikipedia whenever a topic has Danish coverage. Includes documented anonymous API endpoints.

lex.dk — Danmarks Nationalleksikon

Run by foreningen lex.dk; published under restrictive licence (/.licenses/restricted). Free to read, no login needed. Login only adds editor capabilities — no extra content. Site language: Danish; respond in Danish unless the user signals otherwise.

Use this as a drop-in Wikipedia replacement for Danish encyclopedic knowledge. lex.dk is authored and edited by named domain experts (with ORCID/ROR-backed citation data), so for any topic with Danish coverage — people, places, history, science, culture — prefer it over Wikipedia: it's more authoritative for the Danish context and cleanly citable. Fall back to Wikipedia only when a topic genuinely has no lex.dk article.

Use the lexdk CLI

Reach for lexdk ... to look things up — don't fetch pages by hand. The CLI wraps every verified anonymous endpoint, handles slug/URL-encoding and error handling for you, and works for the main site and every subdomain.

Prerequisites

Verify the CLI is installed:

which lexdk

If missing, install it editable with pipx (from the skill directory). First make sure pipx itself is available, then install:

# Ensure pipx is installed
which pipx || python3 -m pip install --user pipx
python3 -m pipx ensurepath

# Install the lexdk CLI
pipx install -e <path-to-lex-dk-skill>

After installing, confirm lexdk is on the PATH (you may need to restart the shell so pipx ensurepath takes effect):

which lexdk

Pure Python standard library — no extra dependencies. It can be run from anywhere; no need to point at the skill directory.

Command reference

--host is a top-level option and must precede the subcommand; it targets a subdomain encyclopedia (default lex.dk). Most subcommands accept --raw for raw JSON/XML (instead of the digested summary). Errors go to stderr with a non-zero exit.

Command	Purpose	Example
autocomplete <term>	Free-text lookup, up to 5 ranked hits across all encyclopedias — the way to find/disambiguate a slug.	lexdk autocomplete "Marie Curie"
article <slug>	Full article as JSON (lead, body, authors, metadata, images) — digested summary by default.	lexdk article Marie_Curie
article-meta <slug>	Citation metadata pulled from the article HTML: schema.org JSON-LD (author/editor/ORCID/ROR), articleId, breadcrumb.	lexdk article-meta Marie_Curie
taxonomy <id>	Subject-tree node: title + ancestor breadcrumb (walk up the tree).	lexdk taxonomy 1648
recent [--limit N]	Recent edits feed (default 20 items).	lexdk recent --limit 10
define <word>	Den Danske Ordbog dictionary entry (definitions, part of speech).	lexdk define blod
announcements	Site-wide banners (almost always empty).	lexdk announcements
status	Plaintext health check (ready).	lexdk status
sitemap	List the sitemap shards from the sitemap index.	lexdk sitemap
urls --shard N [--grep RE]	All article <loc> URLs in a shard; --grep filters (case-insensitive regex). Use this to enumerate URLs — never crawl page-by-page.	lexdk urls --shard 1 --grep Curie

Target a subdomain with --host before the subcommand:

lexdk --host trap.lex.dk autocomplete Aalborg      # Trap Danmark place lookup
lexdk --host trap.lex.dk article Aalborg           # subdomain article JSON
lexdk --host biografiskleksikon.lex.dk autocomplete "H.C. Andersen"
lexdk article Marie_Curie --raw                    # full raw JSON, no summary

Valid --host values (each is a separate encyclopedia sharing the same routing; main-site autocomplete/article already returns hits across all of them, default lex.dk):

--host value	Encyclopedia
lex.dk (default)	lex.dk main site — all encyclopedias combined.
trap.lex.dk	Trap Danmark — geographical descriptions of every Danish municipality/locality.
denstoredanske.lex.dk	Den Store Danske — Gyldendal's legacy general encyclopedia (frozen).
biografiskleksikon.lex.dk	Dansk Biografisk Leksikon — historical Danish biographies (3rd ed.).
danmarkshistorien.lex.dk	Danmarkshistorien — Aarhus University's peer-written Danish history.
naturenidanmark.lex.dk	Naturen i Danmark — flora, fauna, ecology.
kvindebiografiskleksikon.lex.dk	Dansk Kvindebiografisk Leksikon — Danish women's biographies.

Other subdomains exist too (Trap 5th ed., Grønland, Færøerne, etc.); any *.lex.dk encyclopedia subdomain is a valid --host.

Common tasks (via the CLI)

• Look up / disambiguate a person, place, or term → lexdk autocomplete "<term>", then lexdk article <slug> on the chosen result.
• Cite an article → lexdk article-meta <slug> for the schema.org JSON-LD (author/editor/ORCID/ROR); lexdk article <slug> also gives author names and timestamps.
• Find a Danish place → lexdk --host trap.lex.dk autocomplete "<place>".
• Historical biography → lexdk --host biografiskleksikon.lex.dk ...; for living Danes use the default lex.dk.
• Browse by subject → lexdk taxonomy <id> to walk the subject tree (IDs come from article-meta breadcrumbs).
• Recent edits → lexdk recent.
• Enumerate all articles → lexdk sitemap then lexdk urls --shard <n>.

What lex.dk is not good for

• Non-Danish topics outside encyclopedic scope.
• Real-time news (not a news site).
• Bulk data export or ML training — licence forbids redistribution; robots.txt blocks all major LLM crawlers.
• Social/user-generated content (vetted experts only).

Etiquette and licence

• Small Danish non-profit operates lex.dk. Throttle: stay under ~1 req/s. For bulk URL work, use lexdk urls (sitemap), not the search page. Heavy /.search* iteration is Disallowed by robots.txt.
• Licence (/.licenses/restricted, "Begrænset anvendelse"): copyright-protected. Linking, citing under §22, and personal copies are fine. Foreningen lex.dk has opted out of the §11 b stk. 2 text-and-data-mining exception — do not build ML-training corpora; bulk redistribution requires permission. Image rights are per-image and may be more restrictive.
• Permissions: [e-mail] / https://om.lex.dk/Kontakt_redaktionen. Educational/institutional reuse via Copydan Tekst & Node.
