 * **Hierarchical** — represents hierarchical data structures, such as JSON or a tree of JVM objects.
 * **Functional** — the data processing pipeline is organized in a chain of `DataFrame` transformation operations.
-* **Immutable** — every operation returns a new instance of `DataFrame` reusing underlying storage wherever it's possible.

 * **Readable** — data transformation operations are defined in DSL close to natural language.
 * **Practical** — provides simple solutions for common problems and the ability to perform complex tasks.
 * **Minimalistic** — simple, yet powerful data model of three column kinds.
-* **Interoperable** — convertable with Kotlin data classes and collections. This also means conversion to/from other libraries' data structures is usually quite straightforward!

 * **Generic** — can store objects of any type, not only numbers or strings.
-* **Typesafe** — on-the-fly [generation of extension properties](https://kotlin.github.io/dataframe/extensionpropertiesapi.html) for type safe data access with Kotlin-style care for null safety.
-* **Polymorphic** — type compatibility derives from column schema compatibility. You can define a function that requires a special subset of columns in a dataframe but doesn't care about other columns.

   In notebooks this works out-of-the-box. In ordinary projects this requires casting (for now).

 ## Data model
+
 * `DataFrame` is a list of columns with equal sizes and distinct names.
 * `DataColumn` is a named list of values. Can be one of three kinds:
-  * `ValueColumn` — contains data
-  * `ColumnGroup` — contains columns
-  * `FrameColumn` — contains dataframes
+    * `ValueColumn` — contains data
+    * `ColumnGroup` — contains columns
+    * `FrameColumn` — contains dataframes
