A scalable content ingestion and preparation engine is disclosed; the engine incorporates or ingests digital media content and descriptive metadata from disparate sources into a consolidated form, while de-duplicating, data cleansing and resolving inconsistencies across the data sources. In particular, the engine removes errors, duplications and inconsistencies in the metadata and then generates a consolidated collection of digital media files and associated metadata. It makes available the digital media files and associated metadata in the consolidated collection to multiple consumer devices.
