Roadmap

The roadmap describes sequence, not dates or guarantees.

Completed foundation

• Research and architecture review
• API/docs domains, DNS, HTTPS, and independent releases
• Typed API foundation and generated OpenAPI
• Provider and property registries
• Canonical observation/provenance model
• First functional USDA SDA/SSURGO adapter
• Experimental NCSS Lab Data Mart pedon search and observation adapter
• Bounded GeoJSON point discovery and D3 pedon explorer
• Explicit reported-value and detection-limit representation
• Raw/normalized separation, cache metadata, rate limits, and tests
• Markdown documentation, source catalog, and developer examples

Next: classification context

Connect Official Soil Series Descriptions and current soil-series classification context without treating a typical series description as a measured profile. Preserve version/current-status fields and make relationships to sampled pedons explicit rather than assumed.

Then

1. SCAN station catalog and soil moisture/temperature time series
2. USGS geochemical samples, keeping soil/sediment/rock media distinct
3. Canonical vocabulary review with domain contributors
4. gNATSGO/SOLUS and dependable SoilGrids raster ingestion
5. Multi-provider location comparison with compatibility gates
6. Bounded SSURGO polygon and property-summary GeoJSON
7. Hosted accounts, API keys, usage quotas, and service-level policy
8. Community provider and property contributions

Maturity stages

Research → Experimental → Beta → Stable

The API remains Experimental until more than one provider is reliable, compatibility rules have domain review, stable version/deprecation policies exist, and operational monitoring has a meaningful history.
