Processing metadata is considered to be data that indicate from which processing chain a data originates and how the data itself has been produced. Overall, it helps to increase traceability and search among processing levels and multiple algorithm versions.

Often, data items are the result of one or more waterfall processing pipeline. Tracing information such as the processing facility, the algorithm version or the processing date helps in the data version management.
