One of the key principles of Open Data is that it is findable. One way to make this research findable, is through giving a Digital Object Identifier to data.
A Digital Object Identifier (DOI) is a persistent identifier that provides an unchanging address for digital objects that are accessible via the internet. For instance, DOIs are commonly used to create a unique path to articles or datasets, though they can be used for other types of publications such as audio-visual content. Whereas the address for certain webpages may change, DOIs provide a more stable link to content.
When publishing, the organization you are publishing with may automatically apply a DOI to your work. In some instances, however, a publisher may request that you apply a DOI to your work; for instance, if you are submitting a dataset to them and need to make it available online. You can request a DOI for your research by contacting the UNO Libraries' Institutional Repository Coordinator.
