Why This Matters

The Kb Prolog Knowledge Base introduces a sophisticated, local-first, hyper-relational graph system that enables advanced knowledge representation, versioning, and deduplication. Its integration of content-addressable storage and interactive visualization makes it a powerful tool for developers and organizations managing complex data structures, potentially transforming how knowledge bases are built and maintained in the tech industry.

Key Takeaways

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.
