SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Ologs provide a rigorous way to capture domain problems as categorical schemas, turning natural-language descriptions into formal structures that support reasoning and data modeling.

Core Features & Use Cases

  • Propose types (objects) and functional arrows (aspects) that form readable, truthful sentences.
  • Enforce the functional arrow constraint, and use spans to model many-to-many relationships.
  • Map ologs to database schemas via the Grothendieck construction and leverage tooling like CQL, Catlab, and CatColab for exploration and validation.
  • Explore problem-taxonomy design, domain translations, and cross-domain analogies through functor search.

Quick Start

Describe a domain problem and draft an olog with a concise set of types and functional arrows.

FAQPage Schema
What is an ontology log and how does it help with knowledge representation?▼

An ontology log (olog) is a categorical schema that captures domain knowledge as types and functional arrows, translating natural-language descriptions into rigorous structures for data modeling and reasoning.

How do I design a database schema from a domain description using category theory?▼

Design a database schema by defining types as objects and functional arrows as aspects, using spans for many-to-many relationships. You can then map the olog to a database schema via the Grothendieck construction for formal data modeling.

How do I model many-to-many relationships in an olog?▼

Model many-to-many relationships in an olog by using spans. A span connects two types through an intermediate type, maintaining the functional arrow constraint while accurately representing complex relational mappings.

Can I use CQL or Catlab to validate categorical schemas?▼

Yes, you can leverage tooling like CQL, Catlab, and CatColab to explore and validate categorical schemas. These tools support mapping ologs to database schemas and assist in cross-domain translations via functor search.

What is the best way to translate knowledge between different domains?▼

The best way to translate knowledge between domains is through functor search. By constructing ologs for each domain, you can explore cross-domain analogies and map structures to translate knowledge libraries and routing schemas rigorously.

When should I use spans instead of direct functional arrows in an olog?▼

Use spans instead of direct functional arrows when modeling many-to-many relationships. Ologs enforce functional arrows for one-to-one mappings, so spans are required to connect multiple instances across two distinct types accurately.
