Specifications
Open Membership RSS
The canonical 0.4 specification plus the companion specs that extend it. Project documents live under /docs/.
Core
- Open Membership RSS 0.4
The canonical specification. Defines the namespace, discovery document, credential profiles, and conformance levels. Read this first; the companion specs extend it.
Companion
- Subscriber Portability Format 1.0
How a subscriber moves between reader apps without re-subscribing. JSON-LD export of stored tokens, credentials, receipts, bundle memberships, and pending gifts, encrypted with age or JWE.
- ActivityPub Coexistence Profile
Rules for a publisher running both Open Membership and ActivityPub on the same domain. Covers actor mapping, monetization signalling, and avoiding identity collisions across the two stacks.
- Platform Adapter Profile
A normalized shape any closed-platform adapter (Substack, Patreon, Memberful) can target. Defines the surface a publisher-owned bridge must expose to be interoperable with om readers.
- Syndication Mappings (Atom + JSON Feed)
Bidirectional mapping of om elements to Atom 1.0 (RFC 4287) and JSON Feed 1.1. Lets a publisher serve the same paid content over any of the three syndication formats with the same access semantics.
- Sharing Policy Profile
Optional declarations a publisher can make about per-device limits and anti-sharing detection, with reader-side conventions for honoring them. Inspired by Patreon's tokenized-feed enforcement model.
- Errata 0.4.1
Editorial corrections to 0.4. Non-substantive; canonical URI remains the 0.4 namespace.
