Knowledge Ontology

OWL-Based Knowledge Ontology Defining Domains and Relations

The Knowledge Ontology is an OWL-based software schema that defines domains, concepts, and relational taxonomies across the Lunar Ark archive, serving as the semantic backbone for its knowledge graph. Stored in L1-DVT, it organizes 100,000 concepts while consuming 0.5 W of electrical power. Sustaining data integrity across a 100-year operational lifetime and a 500,000-hour mean time between failures presents distinct maintenance challenges, requiring versioned ontology evolution to integrate expanding knowledge, support for multi-language labels, and authenticated update verification across long-duration lunar surface missions.

OWL-based knowledge ontology defining domains, concepts, and relations across the entire archive — providing semantic backbone for knowledge graph.
