SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill addresses the critical issue of data loss in ActivityPub when a server shuts down, by enabling server-independent object identities.

Core Features & Use Cases

  • Portable Object Identifiers: Uses ap:// URIs with Decentralized Identifiers (DIDs) for object identification, making them independent of any single server.
  • Data Integrity & Security: Employs cryptographic proofs (FEP-8b32) and origin-based authentication (FEP-fe34) to ensure data authenticity and security, regardless of the serving gateway.
  • Use Case: Imagine a user's profile and all their posts are tied to a server that unexpectedly goes offline. With portable objects, their identity and content remain accessible through alternative gateways, preventing permanent data loss.

Quick Start

Explain how FEP-ef61 enables server-independent identity in ActivityPub.

Frequently Asked Questions about kb-fediverse-portable-objects

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I prevent data loss in ActivityPub when a server shuts down?▼

Portable objects in ActivityPub use `ap://` URIs containing Decentralized Identifiers (DIDs) to decouple object identities from any single server. This mechanism ensures your profile and content remain accessible through alternative gateways if the original server shuts down.

What is FEP-ef61 and how does it enable portable Fediverse identity?▼

FEP-ef61 is a Fediverse Enhancement Proposal that enables portable Fediverse identity by using `ap://` URIs and Decentralized Identifiers (DIDs). It establishes server-independent object identities, allowing data to persist regardless of the serving gateway's status.

How do portable objects ensure data integrity and authentication in ActivityPub?▼

Portable objects ensure data integrity and authentication in ActivityPub by employing cryptographic integrity proofs via FEP-8b32 and origin-based authentication through FEP-fe34. These mechanisms verify data authenticity regardless of which gateway serves the objects.

Does FEP-ef61 work with existing ActivityPub implementations?▼

FEP-ef61 bridges to existing ActivityPub implementations via FEP-c390. This compatibility allows server-independent `ap://` URIs and DIDs to integrate with current decentralized identity stacks without requiring a complete protocol overhaul.

How does server-independent ActivityPub identity differ from nomadic identity?▼

Server-independent ActivityPub identity using FEP-ef61 differs from nomadic identity concepts by relying on `ap://` URIs and Decentralized Identifiers (DIDs) for object-level portability. It focuses on gateway mechanisms and cryptographic proofs rather than account migration.
