Content metadata service for lifecycle management of digital content

A non-transitory computer-readable storage medium coupled to one or more processors and having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations for content transfer using content management systems, the operations comprising:

• receiving, by a content transfer service of a content management system and from a source system, a first content file comprising first content and first content metadata, the first content metadata being stored in a first format;
• processing the first content file to:
• extract file-type-specific metadata from the first content metadata by executing a set of metadata retrieval definitions in sequence, each metadata retrieval definition comprising a computer-executable, declarative procedure executing at least one static atomic operation, and
• map at least a portion of the file-type-specific metadata to a first uniform content metadata file using metadata value mapping and metadata name mapping, the metadata value mapping receiving file type and file-type-specific name-value pairs to provide content-transfer-specific metadata for inclusion in the first uniform content metadata file, the metadata name mapping being used to map content-specific property names to content transfer service metadata property names for inclusion in the first uniform content metadata file, the first uniform content metadata file having a second format that is different from the first format;
• and
• transferring, by the content transfer service, the first content file and the first uniform content metadata file to a target system, the target system consuming the content at least partially based on the first uniform content metadata file.

A system, comprising:

• a computing device;
• and
• a computer-readable storage device coupled to the computing device and having instructions stored thereon which, when executed by the computing device, cause the computing device to perform operations for content transfer using content management systems, the operations comprising:
• receiving, by a content transfer service of a content management system and from a source system, a first content file comprising first content and first content metadata, the first content metadata being stored in a first format;

• and
• transferring, by the content transfer service, the first content file and the first uniform content metadata file to a target system, the target system consuming the content at least partially based on the first uniform content metadata file.
