Crate ggen_marketplace 

ggen-marketplace: Hyper-Advanced Marketplace System

A ground-up rewrite of the ggen marketplace using cutting-edge Rust patterns:

• RDF-Backed Data Store using oxigraph as semantic foundation
• SPARQL Queries for intelligent package discovery and search
• Generic Associated Types (GATs) for flexible trait definitions
• Higher-Ranked Trait Bounds (HRTB) for lifetime flexibility
• Type-Level Programming to prevent invalid states at compile time
• Zero-Copy Semantics via references and smart pointers
• Advanced Async Patterns with structured concurrency
• Cryptographic Security with Ed25519 signing
• Comprehensive Observability via tracing

Data Model

The marketplace uses RDF (Resource Description Framework) as its data model, with oxigraph as the underlying triplestore. This allows:

• Semantic package relationships
• Flexible schema evolution
• SPARQL-based queries
• Version history as RDF facts
