| bldgs | City centre helsinki composite |
|---|---|
| paved | City centre helsinki composite |
Fills bldgs. The archetype is named 'City centre ', declares target land_cover.bldgs, place helsinki and representativeness city.
Fills paved. The archetype is named 'City centre ', declares target land_cover.paved, place helsinki and representativeness city.
| Composite identity | supported The composite is named CBD, described 'Central Helsinki' and carries profile_type 'Commercial', and both components are the Helsinki archetypes named 'City centre ' carrying place helsinki. Label, description, profile type and components all describe the same thing. |
|---|---|
| Composite target | supported The composite's own target is typology, and each slot takes a component declared for it: the bldgs slot takes an archetype declaring target land_cover.bldgs and the paved slot an archetype declaring target land_cover.paved. No archetype in this database declares attaches_to, which is carried only by the 477 records under records/profiles, so slot fit here is judged on the components' declared target. |
| Own parameter values | not applicable The composite declares no parameters block of its own, so it asserts no value beyond the two archetypes it selects. |
| Composition rationale | not applicable The composite claims no composition source, and the repository records no published rationale for pairing these two archetypes. The components' own selections belong to their composition assessments, not to this review. |
| Place applicability | supported The composite claims place finland, and both components declare place helsinki, which db/places.yml resolves to country finland. Nothing is imported from outside the country the composite claims. The only Finnish building and paved archetypes are the two city-centre entries and the two Kumpula entries, all four of them Helsinki, so a Finnish typology can only be a Helsinki typology in this database as it stands. |
| Representativeness | curation required The composite declares representativeness regional while both components declare city, so one city's archetypes stand for a national typology. The database holds no Finnish building or paved archetype classed regional, so the substitution was not avoidable, but the national reach is the composite's own claim and nothing records the decision to make it. The same city-under-regional pattern holds for every typology whose components come from a named city, so a maintainer should settle it once across the typology set rather than entry by entry. |
| Slot and season mapping | supported An assembly of two existing archetypes into two slots; the composite produces no value of its own. A typology carries no seasonal or wet/dry axis, because the four OHM positions live inside the surface archetypes, so the only mapping made here is one archetype per slot and each slot receives exactly one. |
| Completeness and uniqueness | supported A typology has two component slots and no others: the migration maps the legacy Types table's Buildings and Paved columns into bldgs and paved and nothing else (scripts/migrate_to_records.py), and all fourteen entries under archetypes/typologies fill exactly those two. This composite fills both, so the assembly is complete. Its pair of components is unique: archetypes/surfaces/bldgs/helsinki--city-centre is selected by no other typology, and archetypes/surfaces/paved/helsinki--city-centre is selected only by archetypes/typologies/sweden--traditional-stone-house-neighbourhood, which pairs it with a different building archetype. The name CBD alone does not identify the entry, since archetypes/typologies/china--cbd, archetypes/typologies/switzerland--cbd and archetypes/typologies/uk--cbd-sample-run carry it too. |
Finland's CBD typology is internally consistent in everything a composition review can check from the composite itself. Both components are Helsinki city-centre archetypes, helsinki resolves to country finland, the building slot takes an archetype declaring land_cover.bldgs and the paved slot one declaring land_cover.paved, both of the two slots a typology has are filled, and the label, the description 'Central Helsinki' and the profile type 'Commercial' agree with each other and with what is assembled. The one thing the composite asserts beyond its components is reach: it declares representativeness regional while both components declare city, so Helsinki stands for Finland. The database holds no Finnish building or paved archetype classed regional, so nothing better was available, which makes this an unrecorded decision rather than a wrong selection, and the same decision is embedded in every typology built on a named city. It should be settled once for the set. The components' own compositions and values remain subject to their own assessments; this review does not revisit them.
