20 Aug metadata management

A set of formal (stronger) or informal (weaker) processes for creating and maintaining data about content or knowledge. Metadata can describe key characteristics, such as topic, author, freshness and sensitivity of an organization’s structured and unstructured information assets. Metadata can be embedded in the content, such as tagging in web pages, or held separately, such as ontologies that point to databases and files by URI or URL. The metadata can be used by systems needing the information to improve protection, integration, access, collaboration and sharing, linking, analysis, maintenance and retention. Data about content is needed for many cognitive computing processes.
