kb — Prolog Knowledge Base
A local-first, hyper-relational knowledge base with content-addressable storage (CAS). Built as a Master's thesis prototype.
What it is
Hyper-relational graph : Knowledge is stored as statement(Subject, Predicate, Object, Properties) . Subjects and objects can themselves be statements (reification), enabling claims about claims.
: Knowledge is stored as . Subjects and objects can themselves be statements (reification), enabling claims about claims. Content-addressable storage : Files are staged, SHA-256 hashed, and committed atomically alongside their graph metadata. Deduplication is automatic.
: Files are staged, SHA-256 hashed, and committed atomically alongside their graph metadata. Deduplication is automatic. Time-travel : Updates create new statement versions linked via replaces_id . pl history walks the version chain.
: Updates create new statement versions linked via . walks the version chain. Prolog-first : Trealla Prolog is the main runtime. SQLite and Raylib are accessed via C shared libraries loaded through FFI.
: Trealla Prolog is the main runtime. SQLite and Raylib are accessed via C shared libraries loaded through FFI. Interactive GUI: A Raylib-based graph viewer with image previews, a query bar, and node search.
Build
Dependencies: Clang, X11 (Linux) or Xcode CLT (macOS). Trealla Prolog, Raylib, raygui, and SQLite are included as submodules.
