The Integrated Resource for Reproducibility in Macromolecular Crystallography (IRRMC) is a comprehensive repository and website designed to archive raw data, including metadata from macromolecular diffraction experiments. IRRMC (proteindiffraction.org) was initially funded by the Targeted Software Development award 1 U01 HG008424-01 as part of the BD2K (Big Data to Knowledge) program of the National Institute of Health. Currently, IRRMC activities are supported by Harrison Family Funds and personal funds. The primary IRRMC goal was to create an archive and develop tools for "wrangling" data from protein diffraction experiments.

The 2.0 version of IRRMC, despite the similarity of the user interface, has been redesigned and rewritten, which should result in better metadata extraction, a quicker and more automatized publishing process, and a smoother experience, particularly for researchers who publish new experiment data.

The data come from diffraction experiments used to determine protein structures deposited in the PDB and contributed by the CSGID, SSGCID, JCSG, MCSG, SGC, and other large-scale projects, as well as individual research laboratories.
