FIRM: Federated Information Resource Manager

It's not SoLiD, but it's FIRM.

This is an experimental ActivityPub-enabled federated information resource manager. This library can be used to implement ActivityPub, Linked Data, and similar servers. It's currently not intended to be the basis for a public servers, but rather a platform for experimentation and implementing proof-of-concept for social web ideas.

This library is being used to implement the firm-server, which added network access, simple web interfaces and other features. The firm-server is just an example, other servers can be build with this library. Those servers can use a different web framework, different storage strategies, and os on.

This library is still in the early stages of development, but there are already some potentially useful and interesting features:

Features

These are current features, unless tagged otherwise.

• Python 3 implementation (libraries for other languages being developed)
  • Minimal external dependencies (only cryptography libraries for HTTP signatures)
• Multi-actor
• Multitenant
  • Multiple domains supported on a single server
• Data vocabulary-independent
  • Not specific to ActivityStreams 2.0
• Flexible URIs (supports any HTTP URI path structure)
• Abstract web interface
• Abstract resource store
  • Flexible data partitioning
  • Multiple storage implementations (can be used together)
    • In-Memory
    • File System (JSON)
    • Sqlite3 (JSON)
    • #future deltabase
    • #future MongoDB
    • #future RDF Graph Store
    • #future Neo4J
    • #future File System + git
• Multiple authentication techniques
  • HTTP Signatures (Cavage)
  • HTTP Basic Auth
  • Bearer Tokens
  • Can be used simultaneously (chained)
