+Apache NiFi - MiNiFi C++ is a complementary data collection approach that supplements the core tenets of NiFi in dataflow management, focusing on the collection of data at the source of its creation.
+The C++ implementation is an additional implementation to the one in Java with the aim of an even smaller resource footprint.
+
+Specific goals for MiNiFi comprise:
+
+  - small and lightweight footprint
+  - central management of agents
+  - generation of data provenance
+  - integration with NiFi for follow-on dataflow management and full chain of custody of information
+  - Perspectives of the role of MiNiFi should be from the perspective of the agent acting immediately at, or directly adjacent to, source sensors, systems, or servers.")
