The author of Redis, Salvatore Sanfilippo, calls his software a _data structure store_. Knowfox evolves in the same direction, albeit with a different set of primitives.
With these, Knowfox is more in line with BaaS (Backend as a service) offerings like parse.com.
Two new features justify putting Knowfox into this category:
Configuration now is user specific and adjustable through a special root concept node.
A new API, based on GraphQL by Facebook, allows to serve concepts to apps in a flexible and efficient way.
