Abstract

In accordance with embodiments of the invention, local metadata is embedded into, and extracted from, an embedded interaction code document. A plurality of local-metadata values are assigned, in accordance with a set of local-metadata conflict-resolution rules, via a plurality of respective partial-share channels, to a plurality of respective local-metadata fields. The local metadata is decoded by decoding the partial-share channels and by resolving potentially conflicting decoded local-metadata values according to the set of local-metadata conflict-resolution rules. A local metadata value of a region to the left may be smaller than a local metadata value of a potentially conflicting region to the right, and the values may be non-continuous. A local metadata value of an upper region may be smaller than a local metadata value of a potentially conflicting lower region, and the values may be continuous.
