WorldSeed v0.9.1 — Schema validation hotfix

WorldSeed v0.9.1 — Schema validation hotfix

This patch fixes the published road-graph JSON Schema without changing the v1 data contract.

Fixed

• Reworked the road-graph.json node schema so id, x, y, z, and edgeIds validate correctly under Draft 2020-12.
• Updated schema $id URLs to the v0.9.1 source tag.
• Updated generated WorldSeed version metadata to 0.9.1.

Compatibility

The exported data contract remains schemaVersion 1.0. Existing v0.9.0 export data remains compatible; this release corrects the machine-readable validator definition.

For new integrations, use v0.9.1 or later.

WorldSeed v0.9.0 — Interoperable City Export

WorldSeed v0.9.0 — Interoperable City Export

WorldSeed v0.9.0 turns the project from a browser city demo into a more explicit open interchange layer for game-ready geospatial worlds.

Highlights

• Versioned export contract — JSON Schema v1 for metadata, semantic objects, road graphs, spawn points, and drive routes.
• Schemas ship with every starter kit — exported worldseed.json links to the exact relative schema files included in the ZIP.
• Standalone consumer example — examples/export-consumer/ imports a WorldSeed ZIP without using WorldSeed runtime code, then renders the city, road graph, spawns, and route.
• Dense-city road quality — terrain-following junction patches, trimmed road mouths, curved sidewalk corners, and per-arm crosswalks reduce overlap and z-fighting at intersections such as Shibuya.
• Drive and Drone reliability — collision-safe vehicle spawns, dense-city Drone clearance, and improved iPhone landscape HUD layout.
• Export geometry reliability — normalized geometry batching removes mixed-attribute merge failures.
• Terrain-following road detail — roads, sidewalks, and markings are sampled in shorter terrain-aware segments instead of long planar strips.
• OpenStreetMap fallback hardening — configurable Overpass endpoint plus POST/GET retry behavior.

Export contract

The Three.js kit contains:

• city.glb
• terrain.glb
• colliders.glb
• worldseed.json
• worldseed-objects.json
• road-graph.json
• spawn-points.json
• drive-route.json
• schemas/v1/*.schema.json
• ATTRIBUTION.md
• a minimal Vite + Three.js viewer

See docs/SCHEMA_VERSIONING.md for compatibility rules.

For downstream developers

The project now maintains ADOPTERS.md and an Integration report issue template. Public integrations are listed only after a reproducible artifact is provided; the project's own consumer example is not counted as external adoption.

Status

WorldSeed remains early-stage. Provider availability, dense-city visual fidelity, and export ergonomics will continue to evolve. Schema-major changes will use a new contract family rather than silently changing v1 semantics.
