In recent posts I’ve introduced the notion of Big Content as shorthand for incorporating unstructured content into the Big Data world in a systematic and strategic way. Big Data changes the way we think about content and how we manage it. One of the most important areas requiring a fresh look is metadata. Big Content expands the definition of metadata beyond the traditional tombstone information normally associated with documents (title, author, creation date, archive date, etc.). While these elements are necessary and remain foundational to both effective content management and Big Data, more is required. Big Content metadata encompasses any additional illuminating information that can be extracted from or applied to the source content to facilitate its integration and analysis with other information from across the enterprise. This expanded definition results in a three-tiered metadata architecture for Big Content.
