zlf is a WAM-backed Prolog graph database for building AI-native knowledge bases. It stores graph facts persistently, evaluates queries and rules through a single Prolog runtime, and supports retrieval over the resulting knowledge graph.

What it provides

• Persistent property-graph storage backed by RocksDB
• Prolog facts, rules, and queries executed by a WAM runtime
• BM25 retrieval, optional vector similarity, and temporal queries
• JSON-over-STDIO CLI, HTTP/SSE server, and interactive Prolog REPL
• Compiled-rule persistence and storage-backed fact writes

Quick start

Build the CLI:

cargo build --release

Open a database in the Prolog REPL:

target/release/zlf repl ./zlf-db

Usage

See the usage guide for installation, configuration, REPL and Prolog examples, JSON-over-STDIO commands, HTTP endpoints, index profiles, embeddings, and operational guidance.
