The NASA Scientific and Technical Information (STI) Program is upgrading the NASA STI Repository (NTRS) to enhance discoverability of, and access to, NASA funded STI. The STI Repository promotes the dissemination of NASA STI to the widest audience possible by allowing information to be harvested. In support of these objectives, the upgraded repository has an OpenAPI to provide greater access to publicly available data and further flexibility for dissemination of NASA research results.
The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) was available as a data harvesting service before August 7, 2020. This service is under evaluation as the OpenAPI provides more immediate and greater access to publicly available NASA STI. The OpenAPI is the recommended mechanism for access to NASA’s public collection of STI, and is available along with the following API documentation and guidance:
If you are interested in harvesting from the repository and you have any comments or questions about the process, please contact the STI Information Desk for assistance.
If you harvest from our database, please cite the NASA STI Program as the source of data. Sites interested in harvesting from NTRS should review the following guidance before harvesting:
Use of Government Information
The NASA STI Repository (NTRS) OpenAPI serves out unlimited, unclassified, publicly available NASA citations and full-text documents (PDFs). Persons, organizations, and sites interested in obtaining NASA information should review Disclaimers, Copyright Notice, Terms and Conditions of Use for guidance.
Thank you for your patience as we work diligently to support access and dissemination of NASA data.
