Proposes 14 Known Values for creative contribution roles in Gordian Envelopes.

Roles defined:
Author, Editor, Architect, Designer, Manager, ConceptOriginator, Documenter, TechnicalProducer, Curator, Reviewer, Maintainer, MaterialContributor, Performer, IntellectualContributor

Codepoints: Community range 1060-1073

Designed for cross-creative, medium-agnostic attribution. Maps to existing standards:

• CRediT (ANSI/NISO Z39.104-2022) — now registered at codepoints 2400-2413
• MARC Relator Codes
• ONIX Code Lists
• EBUCore

Seeking rough consensus; willing to use 100000+ range if community prefers.

Updates (Feb 4, 2026)

Per reviewer feedback:

1. Notation: Changed CID(...) → Digest(...) per Issue BCR notation question: Content-addressed envelope references in examples #157 resolution
2. Schema.org alignment:
   • hasContributor → schema:contributor
   • role → schema:roleName
   • Author/Editor role values replaced with direct schema:author, schema:editor predicates
3. NISO CRediT alignment: Replaced ConceptOriginator with niso-credit:Conceptualization
4. Cross-reference fixes: Fixed references to BCR-007 codepoints

[ChristopherA]

Per Wolf's feedback: removed { } envelope wrapping from examples that don't include signatures. Wrapping is only needed when showing signed envelopes.
