Credentials
resultDescription
An Open Badges 3.0 array on the achievement that defines possible scored outcomes — the class-level counterpart to the instance-level result.
credentialSubject.achievement.resultDescription is an OB 3.0 array that defines the kinds of scored outcomes a credential can carry. Each ResultDescription entry has an id (IRI), a resultType (GradePointAverage, RawScore, LetterGrade, etc.), a valueMin / valueMax for bounded score types, and a description.
A Result on the CredentialSubject then references a ResultDescription by IRI and supplies the actual value. The separation lets a single achievement describe its grading rubric once and apply it consistently across all awarded credentials.
Like [result](/glossary/result), resultDescription is currently display metadata in LearnCoin credentials — not cryptographically committed pending the LearnCoin extension context publication. Tenants can populate it on POST /v1/batches and it renders on the verification page today.
