LearnCoin JSON-LD context

Also known as: schema.learncoin.me/v1/context.json

The LearnCoin-hosted JSON-LD context carrying LearnCoin extension fields (awardingBody, result, evidence, difficulty, actualDuration) — publication pending.

The LearnCoin JSON-LD context at schema.learncoin.me/v1/context.json is the extension context that defines LearnCoin-specific and OB-3.0-adjacent fields not covered by the upstream v3.0.3 OB 3.0 context. Publication is pending behind the content-stabilization work.

Fields the LearnCoin context will define: awardingBody (OB 3.0 standard but not in v3.0.3 JSON-LD), resultDescription (same), result, evidence, difficulty (LearnCoin extension), actualDuration (LearnCoin extension), related_credentials (LearnCoin extension), tenant_metadata (escape hatch).

Once published, LearnCoin credentials' @context array will include the extension URL as the fourth entry after VC 2.0, Blockcerts v3, and OB 3.0. Today, these fields are emitted as display metadata on the verification page but are not cryptographically committed to the signed JSONLD — URDNA2015 safe-mode canonicalization drops undefined terms.

URL stability is critical. JSON-LD context churn silently breaks verification. The context URL will be immutable per version, year-long-cacheable, and served from a CDN with failover mirrors.
