RULE-BASED METADATA TRANSFORMATION AND AGGREGATION FOR PROGRAMS

摘要

A method and devices for obtaining metadata associated with programs from multiple metadata sources. Title metadata is compared to determine if any title metadata match. Transformation rules are applied to the title metadata when title metadata does not match with other title metadata. The transformation rules transform the title metadata into a common format. The title metadata is compared after transformation to determine whether the title metadata matches other title metadata. Title metadata that matches other title metadata, the metadata associated with a program is aggregated.
