Standard Service Features
Standard features of this service are:
- The Repository & Open Science Access Portal (ROSA P) is the National Transportation Library’s (NTL) digital repository service, available at: https://rosap.ntl.bts.gov/
- ROSA P is home to significant transportation research and transportation statistical publications and datasets, which have value to federal, state, and location transportation decision-makers, transportation analysts, and researchers.
- ROSA P is the repository instantiated by NTL to meet the mandates of the USDOT “Plan to Increase Public Access to the Results of Federally-Funded Scientific Research” (Public Access Plan).
- ROSA P is a cloud-based digital repository for transportation research, including data. ROSA P also provides robust backup of items.
- ROSA P features both simple and advanced search options to improve user search outcomes.
- ROSA-P is a production level system that what gone through USDOT formal ATO process and meets all USDOT security requirements.
- All resources in ROSA P are in the public domain and/or explicit permission has been provided by the rights holder to NTL to make their materials available for free over the web.
- All resources deposited into ROSA P will be assigned a persistent identifier. This globally unique link will always lead users to a landing page containing the resource and its metadata or a description documenting the alteration and/or destruction of the information resource, if applicable. The persistent identifier will always resolve to a landing page with metadata describing the curation of the resource, even if the resource itself is removed.
- ROSA P allows interested users to access records and/or record metadata through an OIA-PMH RESTful API service. Full guidance on this access is available in the ROSA P “Help” menu.
- In order to maximize data findability, accessibility, interoperability, and re-use, ROSA P is operated in concordance with the FORCE 11 FAIR Principles https://www.force11.org/group/fairgroup/fairprinciples

- Datasets will have relational links to associated reports;
- NTL will apply appropriate metadata, subjects, and Transportation Research Thesaurus (TRT) << http://trt.trb.org/ >> terms to catalog records in ROSA P to maximize discoverability through web-based search engines such as Science.gov << https://www.science.gov/ >> and Google Scholar << https://scholar.google.com/ >> ; and,
- NTL will supply links to ROSA P records to the Transportation Research Board’s (TRB) Transportation Research International Database (TRID) << https://trid.trb.org/ >> for insertion in indexing records.
Standard Service Issue Tracking and Reporting
