How can we trust the integrity of results from research that relies on computations without repeating them? By certifying the successful original execution of a computational workflow that produced findings in situ. With certifications in hand, consumers of research can trust the transparency of results without necessarily repeating computations. The TRACE project is developing techniques and tools for certifying the results of computational research. This includes the creation of technical specifications for describing and certifying research artifacts as well as the development of reusable software tools

Whole Tale is an NSF-funded Data Infrastructure Building Block (DIBBS) initiative to build a scalable, open source, web-based, multi-user platform for reproducible research enabling the creation, publication, and execution of tales – executable research objects that capture data, code, and the complete software environment used to produce research findings. A beta version of the system is available at The Whole Tale platform has been designed based on community input primarily through working groups and collaborations with researchers.
