Substance.Data is a data representation framework for Javascript. It's being developed in the context of Substance, an open publishing platform.

• Model your domain data using a simple graph-based object model that can be serialized to JSON.
• Traverse your graph, including relationships using a simple API.
• Manipulate and query data on the client (browser) or on the server (Node.js) by using exactly the same API.

• Data.Graph (A data abstraction for all kinds of linked data)
• Persistence (You can persist your data to a Data.Store)
• Operational Transformation (for incremental updates)
• Versioning (Every graph operation is remembered and can be reverted)
