A synthetic register of UK joinery and carpentry workshops, styled like an
excerpt from a Guild of Master Craftsmen trade roll. It is the clean base
table for the linkage examples: distinctive workshop names paired with
boilerplate trade and legal-form terms, so the rarity-versus-boilerplate
behaviour of the matcher is visible. Pairs with workshop_listings, the
messier external directory. Block on (postcode_area, trade).
Format
A tibble with 1,052 rows and 15 variables:
- reg_no
Character registration number, the base id. Most are
"GMC-#####"; planted duplicates, homonyms, and shared-venue rows carry"GMC-D####","GMC-H####", and"GMC-V####"prefixes respectively.- workshop
Canonical business name (distinctive stem plus trade and legal-form boilerplate)
- proprietor
Proprietor name
- trade
One of eight woodworking trades; half the blocking key
- legal_form
Ltd, LLP, Partnership, or Sole Trader
- postcode_area
UK outward-code area (e.g. "LS"); half the blocking key
- town
Town for the postcode area
- address
Street address
- established
Year the workshop was established
- employees
Headcount, varying with legal form
- apprentices
Number of apprentices
- guild_member
Logical, whether a current guild member
- sic
UK SIC 2007 industry code for the trade
- true_entity
Evaluation only. Same-entity key: planted duplicate rows share it, homonym workshops get distinct keys.
- gen_tier
Evaluation only. Which generation tier the row belongs to. Three rows are
hub_trap: short-named shared venues ("Trinity Workshops", "The Forge", "Riverside Works") that are themselves guild registered. Their two-token names are a forward-containment subset of every<workshop>, <venue>listing, so they bait an exact containment strategy into merging unrelated workshops; themin_containment_tokensguard blocks them.
Source
Synthetically generated. Distinct workshop identities come from a
frozen LLM seed (data-raw/llm_workshop_seed.R); all geography,
colour columns, planted duplicates, and homonyms are added by the seeded,
offline data-raw/generate_workshop_example.R. Ships no real business.
