speciesKey string Species key
Stable Landscape Archive identifier for a canonical species record.
185 — Landscape Archive metadata standard (climate screening extension)
TLA-185 field registry
First visit? Prefer a plain-language overview of dictionary, terms, and the schema pack? Read In plain language on Industry & practice, then follow the adoption quickstart — download the open pack, validate an example bundle, and add the procurement sentence to one deliverable. No account required. The Foundation operates under interim stewardship; the specification and tooling are public reference infrastructure.
The published specification describes 185 documented elements across 16 modules — structural definitions only, with no species inventories, trait values, or client records. Below is a public preview of 28 representative fields. The full, searchable Landscape Data Dictionary — every term with a definition, a stable citable identifier, and a way to propose a change — plus JSON Schema modules and worked examples live on the schema portal and GitHub.
What the standard covers
TLA-185 documents 185 elements as an open, citable field registry. These four domains describe what the specification covers — structural definitions only. Populated species inventories, trait values, and client records are licensed separately and are not part of the open layer.
- 01
Botanical truth
Precise, auditable taxonomic claims so planting records stay legible after handover.
- Resolvable taxon identifiers
- Scientific name, native status, growth form
- Botanical asset rows reconstructable without proprietary joins
- 02
Climate & risk
The metadata shape for site context, climate screening, and sustainability disclosure.
- Banded site-context and climate screening fields
- Risk and sustainability fields with method notes
- Evidence URIs on disclosure claims
- 03
Open research
A stable, citable reference independent of any single vendor’s access.
- Canonical specification, schemas, and worked examples
- Stable field identifiers and JSON paths
- Citation-ready under CC BY-NC-ND 4.0
- 04
Digital twin interface
A documented reference layer for procurement and digital twin programmes.
- IFC property-set alignment
- GeoJSON civic registry bindings
- Machine-checkable interchange baseline
Built-environment export profiles
These interchange profiles map registered field identifiers to external delivery shapes — export bindings of the same canonical record, not parallel standards. JSON schemas and validated emitters are published on the schema portal with worked examples.
-
IFC property sets
MVPIFC4 property sets (JSON)
Map botanical and delivery fields to IFC4 Pset_TLABotanical and environmental indicator subsets for BIM exchange.
Schema -
GeoJSON civic registry
MVPGeoJSON FeatureCollection
Civic registry records — point placement, 2D canopy footprint, taxonomic identity, and maintenance fields.
Schema -
USD metadata sidecar
MVPUSD customData sidecar (JSON)
LOD mesh references, seasonal asset paths, and tracking metadata for real-time visualisation pipelines.
Schema -
Spreadsheet crosswalks
DraftSpreadsheet column mapping
Nursery stock and maintenance spreadsheet headers mapped to canonical field-registry JSON paths for civic stock lists.
Schema
Interchange profiles are export bindings of the same canonical record — not parallel standards. Schemas and worked examples live on the schema portal.
