 ## Frameworks
 
 The fundamental object of CISO Assistant for compliance is the framework. It corresponds to a given standard, e.g. ISO27001:2013. It mainly contains requirements nodes. A requirement node can be assessable or not (e.g. title or informational elements are not assessable). Assessable requirement nodes can be simply called "requirements".
-The structure (tree) of requirements is defined by the level and requirement node objects. The *parent_urn* of a requirement node can either be the URN of another requirement node or null for top-level objects. This allows to simply define the structure of a framework. An assessable requirement node can be the child of another assessable requirement node, which is very convenient for frameworks that have lists of conditions attached to a requirement.
-
-The requirement level objects of a framework optionally provide the naming of each level from 1 to n, when applicable. Requirement nodes have a nullable *level* field to refer to the corresponding requirement level. If requirement nodes are set at a defined level, the term "requirement" is replaced by the name of the correponding level (e.g. "subcategory" for CSF).
-
-If no level information is provided, requirement nodes will be displayed without reference to a notion of level, only as a tree containing requirement nodes. This can address potential frameworks with branches of various depths.

 The maturity field describes the maturity level of the requirement node, when this is relevant (e.g. for CMMC or CIS).
