1. A non-transitory processor-readable medium storing code representing instructions to be executed by a processor, the code comprising code to cause the processor to: receive an uncompressed template definition file (TDF) in a template file format, the uncompressed TDF including an uncompressed set of attributes associated with a taxonomy tree of an online marketplace, the uncompressed set of attributes including a first attribute and a second attribute, the first attribute being at a first level of the taxonomy tree, the second attribute being at a second level of the taxonomy tree; define an association within a database table linking the first attribute with a third attribute based on the first attribute having a characteristic and the third attribute having the characteristic; define an association within the database table linking the second attribute with the third attribute based on the second attribute having the characteristic and the third attribute having the characteristic; compress the uncompressed TDF to define a compressed TDF in the template file format, the compressed TDF including a compressed set of attributes associated with the taxonomy tree of the online marketplace based at least in part on (1) the association linking the first attribute and the third attribute and (2) the association linking the second attribute and the third attribute, the compressed set of attributes including the third attribute and excluding the first attribute and the second attribute; and send the compressed TDF to a taxonomy platform such that a set of inventory data associated with a merchant is mapped, based on at least the compressed TDF, to the compressed set of attributes associated with the taxonomy tree of the online marketplace.
