Data are the result of each research process in all subject areas. Primary or raw data can be very different (data of analyzing, results of polls or surveys, diagrams, photos, videos, drawings etc.), but most of them are available in electronic format today.
After finishing a research project it seems to be useful, to keep such data. They serve as reference for own publications and can be used in other projects. More and more information institutions think about the effective publication and use of research data. Similar to journal articles yet today research data can get so-called DOIs, Digital Object Identifier, to enable easily citing and linking.
More on research data offers the Information Portal “Research Data Infrastructures”, e.g. a German “Handbuch Forschungsdatenmanagement” from 2011, or the data management website by the MIT libraries.
