Memory-efficient programmatic transformation of structured data

Abstract:

A system includes a processor configured to obtain a sequence of transformer rules. The transformer rules specify a set of data elements arranged according to a first structured data format, and structural changes to be performed on the data elements that convert the data elements into a second structured data format. The processor receives a block of data from a file arranged according to the first structured data format. The processor executes the sequence of transformer rules to perform the structural changes to the block of data. When executing the particular transformer rule, the processor applies an adapter associated with the transformer rule to modify values in the block of data specified by the particular transformer. The processor then provides for display or storage the block of data as converted into the second structured data format by the sequence of transformer rules.
