A hierarchical encoder is operable to create a hierarchical multi-layer data package. The hierarchical multi-layer data package includes a plurality of layers and one or more subpackages in each layer. The layers include one or more subpackages. A subpackage in an outer layer is related to a subpackage in an inner layer. Also, each subpackage includes meta data describing the encoding, a summary of a subset of data in the hierarchical multi-layer data and a link or ID of the subset of data in a compressed form.
