Franz Inc. (Allegro CL / AllegroGraph)
Knowledge graph database and Common Lisp environment for enterprise AI applications.
Franz Inc. supplies the AllegroGraph semantic graph database platform and the Allegro CL Common Lisp programming environment. AllegroGraph combines RDF, OWL, SPARQL, vector search, document data, reasoning, and LLM integration for building enterprise Knowledge Graphs, Context Graphs, and Neuro-Symbolic AI applications. The latest version includes GraphTalker, a natural-language interface for asking questions, exploring semantic models, generating and refining SPARQL queries, and producing explainable answers grounded in governed enterprise data. Context Graphs capture business meaning, relationships, provenance, policies, constraints, access rules, metadata, and operational context so AI systems can reason across databases, documents, applications, APIs, and analytical systems.
AllegroGraph is a horizontally scalable, transactional Graph, Vector, and Document Database Platform. Allegro CL provides a Common Lisp environment with AllegroCache for persistent objects, Allegro Prolog and Pcache for logic programming and querying, AllegroServe and Allegro Webactions for web applications, XML parsing, connectivity tools, an IDE with Common Graphics, and a browser-based IDE. Version 11.0 adds LLM integration, knowledge graph and vector storage via AllegroGraph, ARM and Apple Silicon support, and MariaDB compatibility. The platform is offered through free downloads, cloud login, and consulting services, with Allegro CL available as a free download and AllegroGraph offered through purchase and licensing options.
