Metadata is data that provides information about other data. In the context of research, metadata refers to information about a research project, dataset, or publication. This information may include details such as the title, author, date of creation, keywords, and file format of the research data. Metadata is important for organizing and managing research data, making it easier to search, access, and retrieve. It also helps ensure the quality, accuracy, and integrity of research data by providing context and documentation about how the data was collected and processed. Metadata standards and best practices are often used to ensure consistency and interoperability of research data across different platforms and disciplines. Overall, metadata plays a crucial role in facilitating the discovery, sharing, and reuse of research data.
