Overview
Each Collection TCIA publishes is issued a Digital Object Identifier (DOI) through DataCite. The DataCite Commons is a web search interface for the PID Graph, the graph formed by the collection of scholarly resources such as publications, datasets, people and research organizations, and their connections.
The DataCite REST API can be used to programmatically access Collection metadata such as their DOIs, titles and abstracts. Please note that this API was not developed by TCIA. See https://support.datacite.org/ for any technical questions. The TCIA Helpdesk may be able to assist if your inquiry is related to the content of the data itself.

| 5 | PublicationYear | The Year the Dataset was published in TCIA |
| 10 | ResourceType | Dataset; Equivalent to a TCIA Collection |
| 11 * | AlternateIdentifier | TCIA "Short Name" for the Dataset. These short names appear in various places such as https://www.cancerimagingarchive.net/collections/ and https://www.cancerimagingarchive.net/tcia-analysis-results/ |
| 15 * | Version | The Current Version of the Dataset |
| 16 * | Rights | Licensing Information |

An example notebook demonstrating tcia_utils functionality with DataCite's API can be found at https://github.com/kirbyju/TCIA_Notebooks/blob/main/TCIA_DataCite_Queries.ipynb.
Example Queries
Retrieve a single DataCite record in JSON format.
For this example we are using a Published Collection called "Pseudo-PHI-DICOM-Data":
Return a list of DOIs using the TCIA provider id (tciar)
https://api.datacite.org/dois?provider-id=tciar
By default, only 25 records are returned. You can control the number of records returned using pagination options. For example, to return only 5 records
https://api.datacite.org/dois?provider-id=tciar&page[size]=5
or
Query on specific information populated in the DataCite schema
For instance, return the records published by The Cancer Imaging Archive that were published in 2016:
or
Use the "activities" endpoint to see metadata updates in JSON format for a specified DataCite record.
For this example we are using a Published Collection called "Pseudo-PHI-DICOM-Data":
