Institutional Repositories (IRs) are digital collections of the outputs created within a college or research institutions and provide a way to collect, preserve and provide access to scholarly work. This can include content produced by faculty staff and students.
Content in IR collections can include:
Open Access Institutional Repositories and Archives are designed to make this content widely available on the web. By following international standards like the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), contents are indexed and widely accessible through Google and other search engines. By opening up the scholarly content of an institution to the world, institutions showcase academic research with interested parties and encourage the development and sharing of interdisciplinary research.
The Open Data movement is a subset of the broader Open Access movement that seeks to encourage the sharing of research data with other researchers as well as with the public at large. The Open Data movement promotes transparency in research, collaborative and team science, and the re-use and re-purposing of research data. Research data can be defined as "the recorded factual material commonly accepted in the scientific community as necessary to validate research findings." (OMB Circular 110). This broad category can include texts/documents, lab/field notebooks, maps, genomes, chemical compounds, medical records, survey results, interview transcriptions, biological images, EKG waves, and more.
While some institutions preserve and provide access to research data through their institutional repositories, it is more common to find separate institutional or disciplinary repositories just for research data, due to the specialized nature of these materials. Data in the sciences is often shared through disciplinary repositories - some are highly specialized, such as GenBank, while others, like the Harvard Dataverse Network, cover the sciences and social sciences more broadly.
Open data is also often found from governments that provide their administrative data to the public. The United States Census and American Community Survey are two of the most well known examples of this type of data, but many other countries have been making their data more open and accessible. The Open Knowledge Foundation maintains a web page that tracks open goverment data around the world.
