+* Concept
+The traditional hierarchical file system (folders and files) is replaced by a system-wide database of objects retrieved via key/value attributes.
+
+* Key Principles
+- **Attribute-Based Retrieval:** Objects are not "located" in a path but retrieved via metadata (e.g., `:author`, `:date`, `:category`).
+- **Semantic Storage:** Data maintains its structural meaning. A "Note" or "Document" is a Lisp object, not just a raw byte stream.
+- **Directories as Objects:** Directories are simply specialized objects containing a list of object entries and their attributes, allowing for non-hierarchical organization where one directory can store another.
