Metadata is the "data" that describes your research data by summarizing key information related to its production and nature. Author, date created, and study title are very basic examples. The purpose of metadata is to ensure that the data remains interpretable for the researcher, colleagues, or the public, making working with it easier. Best practices recommend that metadata is as complete and descriptive as possible in order to optimize re-usability. Effective metadata through increased interpretability and re-use increases citation of the original research project.
Data Curation Commons maintains an archive of discipline-specific metadata standards.
