Third-party schema provenance

OSD profiles Agentic Resource Discovery (ARD). The vendored ARD schemas retain their source annotations in $comment.

ARD v0.91

Contract set 0.3.0 pins upstream revision aa3e598bb7752a9175897823234311216acfa864 and its spec/schemas/ard-entry.schema.json. The copy changes only the schema ID and source annotation.

The license from that upstream revision is included at contracts/licenses/ard-0.91.txt.

Additional vendored source material

The repository also retains ARD v0.9 source copies from revision 5fa2f5aef790b478319f6a3b43adf4661b0ed0e0 and its spec/schemas/ai-catalog.schema.json. Their $comment annotations identify schema ID changes and, where applicable, the adjustment allowing nested metadata values. The corresponding license is included at contracts/licenses/ard-0.9.txt.

Both upstream licenses specify Apache License 2.0. They do not establish a project-wide license for OSD content.
