To facilitate data sharing, many publications encourage authors to include data citations to the data that the authors used in creating the results described in their scholarly papers. In addition, new journals are now available for describing data collections outright. As a service to the community, TCIA now has the ability to create persistent identifiers to subsets of data held within TCIA that authors may use as data citations in their scholarly papers.
TCIA uses the DataCite system to manage these references. DataCite leverages the Digital Object Identifier (DOI) infrastructure, which is widely used in citing scholarly articles. TCIA users may request that a DOI be created for subsets of data stored within TCIA.
To request a DOI for a subset of data, the TCIA user must first identify the subset of data that will be referenced by the DOI. The best way for a user to identify this subset of data is to create a shared list using TCIA's NBIA web application. By definition, only publicly available data may be included in the shared list. Creating a DOI to private data is not allowed. Currently DOIs created by TCIA may only reference static (unchanging) subsets of data. In other words, if someone changes the content of the shared list, this will not be picked up by existing DOIs created from that shared list.
Once a user has create a shared list, they may request that a DOI be created by sending an e-mail message to TCIA's help desk with the following information:
Once TCIA validates the request, they will create a DOI landing page for the citation and associate a DOI with that landing page. The landing page will include a link that allows readers to directly download the subset of data cited. The help desk will then inform the requestor when the new DOI is ready.
