Open Knowledge Format v0.2 enhances agentic trust and provenance

The new 'sources' field in OKF v0.2 allows concepts to record their origins, such as external documents or specific scopes. It also includes objective credibility signals like author, usage_count, and last_modified, letting consumers infer credibility rather than relying on static scores.

OKF v0.2 distinguishes between how content was produced ('generated') and who confirmed it ('verified'). The 'verified' field supports a list of independent confirmations, enabling consumers to derive trust tiers (unverified, machine-confirmed, human-reviewed) as advisory signals.

OKF v0.2 adds optional frontmatter fields to address agentic trust, allowing consumers to evaluate provenance, trust, freshness, lifecycle, and attestation. These signals are designed to provide accountability in environments where agents generate knowledge continuously.

Version 0.2 builds upon OKF v0.1 by adding optional vocabulary rather than strict rules. The format remains minimally opinionated, preserving custom keys and ensuring bundles that adopt none of the new additions are still valid. The core 'type' field remains the only required element.

The new frontmatter fields are designed to provide concise signals for consumers to make quick decisions about a concept's relevance and trustworthiness before accessing its full content. This optimizes interactions, especially in search and discovery scenarios.
