XGML Standard

Explainable Graph Markup Language for verifiable AI exchange.

XGML defines a structured reasoning contract: claims, evidence, proofs, and signatures that survive model boundaries and regulatory scrutiny.

XGML standard identity

Portable Schema

XGML payloads move across models and vendors without losing reasoning structure.

Signed Evidence

Proof envelopes support cryptographic signatures for non-repudiable audit records.

Open Governance

Spec evolution is tracked in public with changelogs, proposals, and review workflows.
