A structured, minimal, and extensible foundational ontology designed for clear human navigation and AI-assisted exploration.
This project aims to organize knowledge through explicit ontological domains, hierarchical relations, and cross-linked concepts using plain Markdown files.
It is not an encyclopedia.
It is a structural framework for describing what exists, how it exists, and how entities relate to each other.
"Structura" provides:
- A domain-based classification of entities
- Explicit hypernym / hyponym relationships
- Clear separation of physical, mental, social, and formal domains
- Cross-domain linking for multidimensional entities
- Markdown-native structure for transparency and portability
- AI-readable structure without requiring proprietary formats
The goal is clarity, not completeness.
- Minimal top-level domains (under 10)
- Clear ontological separation between types of existence
- Hierarchical structure with graph-based linking
- Explicit metadata for every concept
- No metaphysical assumptions without labeling
- Extensible and modular architecture
Entities that occupy space-time and have measurable properties.
Includes:
- Matter
- Objects
- Physical Processes
- Energy Forms

Each entity is defined in a single Markdown file.
Example structure:
# Entity Name
Definition:
Concise and domain-neutral definition.
Ontological Domain:
(Physical | Biological | Mental | Social | Formal | Informational | Hypothetical)
Parent:
Immediate hypernym.
Children:
List of direct hyponyms.
Mode of Existence:
Physical / Abstract / Dependent / Collective / Cognitive
Dependencies:
What must exist for this entity to exist.
Related Entities:
Cross-domain links.
Examples:
Concrete examples.

This repository combines:
- Hierarchical classification (folders)
- Networked relations (internal links)
- Explicit ontological typing
Folders define primary domain. Links define multidimensional relations.
Reality is not a tree. This structure acknowledges that by combining hierarchy with graph semantics.
- Not a dictionary
- Not a wiki clone
- Not a belief system
- Not a complete model of reality
It is a structured experimental ontology.
- RDF / JSON-LD export layer
- Machine-readable metadata layer
- Automated relation validation
- Visualization graph layer
- Cross-language semantic alignment
