+## Key Components
+
+1. **RhizomeNode**: The main entry point that coordinates all other components
+   - Manages the node's lifecycle and configuration
+   - Coordinates between different subsystems
+
+2. **Delta**: The fundamental data unit
+   - Represents atomic changes in the system
+   - Contains pointers to entities and their properties
+
+3. **Lossless**: Manages the lossless view of data
+   - Maintains the complete history of deltas
+   - Provides methods to view and compose entity states
+
+4. **QueryEngine**: Handles data queries
+   - Supports filtering with JSON Logic
+   - Works with the schema system for validation
+
+5. **StorageQueryEngine**: Handles storage-level queries
+   - Interfaces with the underlying storage backend
+   - Optimized for querying persisted data
+
+6. **SchemaRegistry**: Manages data schemas
+   - Validates data against schemas
+   - Supports schema versioning and evolution
+
+7. **DockerOrchestrator**: Manages containerized nodes
+   - Handles node lifecycle (start/stop)
+   - Manages networking between nodes
+
+## Data Flow
+
+1. Deltas are received through the DeltaStream
+2. Lossless processes and stores these deltas
+3. Queries can be made through either QueryEngine (in-memory) or StorageQueryEngine (persisted)
+4. The system maintains consistency through the schema system
+5. In distributed mode, DockerOrchestrator manages multiple node instances

+# Resolvers (Views)
+
+The workhorse of this system is likely going to be our lossy views.
+This is where the computation likely generally occurs.
+
+So, let's talk about how to create a view. 
+
+A lossy view initializes from a given lossless view.
+The lossless view dispatches events when entity properties are updated.
+
+View semantics are similar to map-reduce, resolvers in Redux, etc. 
+
+The key is to identify your accumulator object. 
+Your algorithm SHOULD be implemented so that the reducer is a pure function.
+All state must therefore be stored in the accumulator.

+# Dimensions
+
+Deltas are a hyperstructure capable of expressing many structures.
+
+We can consider models which we compose by expressing their dimensions, and
+relationships between those dimensions. This can enable a robust form of multi-dimensional
+composition. I'm thinking in terms of vectors and matrices, maybe quaternions, tensors.
+
+So basically we can use deltas to encode math.
