Metadata is information that describes other data, helping identify and organize it. Dublin Core and ISO 11179 are standards for creating metadata to improve data sharing. XML and RDF are languages for structuring data and metadata, making them understandable by computers. The Dublin Core Metadata Initiative develops common standards for digital resources. W3C is an organization setting web standards, including schema.org, which helps search engines understand web content. Jisc supports education and research standards, while IEEE LOM focuses on metadata for learning objects. Semantics relate to meaning; data governance manages data quality, and information architecture organizes information. Metadata schemas define data structures, and content management involves organizing digital content efficiently.
