Status and Resources

Current Status

• Operational: Classical C++ AtomSpace (mature, production-grade); Hyperon Experimental Rust reference (active development, Python packages available); Space API abstraction with multiple backends
• Under development: MORK as primary high-performance Space backend; MeTTa-4 semantic model alignment; Windows Python packages for Hyperon Experimental
• Proposed: Neural Spaces (DNNs as queryable AtomSpaces); Rholang AtomSpace for decentralized execution; native MeTTa-to-machine-code compilation

Open Problems / Research Directions

• Convergence of the classical C++ type hierarchy and Hyperon's minimal 4-variant system — which atom types should be primitive vs. user-defined?
• Space API standardization across implementations (MORK, DAS, hyperon-experimental, JeTTa)
• Neural Space design — defining meaningful match/bind/rewrite semantics for embedding-backed AtomSpaces
• Formal metagraph theory — extending the sheaf-theoretic foundations to cover the full Hyperon Space API
