OCA DAG

Rust implementation of OCA DAG

oca-dag-rs — model your Overlays Capture Architecture as a versioned, traceable graph.

It lib for managing Directed Acyclic Graphs (DAGs) that represent the structure and evolution of Overlays Capture Architecture (OCA) bundles. It serves as a foundational layer for versioning, history tracking, and dependency management in systems built on the OCA model.

Features

• DAG-based Model Management Represents OCA data (capture bases, overlays, bundles etc.) as a Directed Acyclic Graph, enabling clear and scalable relationships between versions and components.

• Powerful Versioning System Every change to an OCA bundle—whether it's a new overlay, update, or branching—forms a new node in the DAG, supporting sophisticated version control.

• Full History Tracking Enables tracking of the complete change history of an OCA bundle, including merges and branches/forks, akin to Git-like semantics.

• Dependency Resolution Naturally handles dependencies between capture bases, overlays, and other OCA elements via parent-child relationships in the graph.

• Current State Representation Maintains a clear representation of the current state of a bundle

• Graph Construction Allows for the construction and updating of the DAG from a stream of input commands, effectively modeling the evolution of OCA bundles over time.

Use Cases

• Versioning of OCA bundles
• Collaborative OCA editing with conflict resolution
• Auditing and provenance of overlays and capture bases
• Programmatic traversal and analysis of OCA dependencies
