Abstract
An exemplary global listings format (GLF) is metadata for electronically transferring multimedia programming content and electronic program guide information. The GLF metadata specifies a self-referential data structure having a self-consistency mechanism comprising interlocking and crosslocking data elements. The self-consistency mechanism ensures completeness and validity of transferred programming data. In one implementation, the exemplary GLF is expressed in an extensible markup language (XML) schema definition (XSD) specification.
