A method adapts a dataflow instance. A set of source data nodes, a set of terminal data nodes, and a set of computation nodes in the dataflow are identified from a directed graph. The set of computation nodes performs operations on data flowing from the set of source data nodes through computation nodes and onwards to terminal data nodes in the dataflow. The data nodes are evaluated with policies and a user context. A number of transformation compute nodes is computed from the policy decisions and added downstream of the set of source data nodes and optionally upstream of the set of terminal data nodes when the data, the dataflow or system does not meet the declared policies without the necessary computed number of transformation compute nodes. The number of transformation compute nodes are an additional portion of the overall set of computation nodes to enforce the declared policy.

Enforcing policy in dataflows

A plurality of base templates is generated. Each of the base templates models a corresponding process. A plurality of instances of each of the base templates is instantiated. Each of the plurality of instances corresponds to an application of the corresponding process to a particular environment. Each of the instances of each of the base templates is annotated, based, in each case, upon observation of functioning of the instance in the particular environment.
