Materials Resource Registry allows for the registration of materials resources, bridging the gap between existing resources, software and repositories and end users. The Materials Resource Registry functions as a federated service, making the registered information from multiple institutions available for research to the materials community. https://materials.registry.nist.gov/
The MRR is a comprehensive inventory of high-level data collections, repositories, databases, tools, software, and services useful to materials research and design but located anywhere in the world. Its specialization for Materials Science is in the domain-specific metadata and vocabulary it can leverage to find data on behalf of its users. The MRR can be a tool that scientists access directly through a web site, but its power can also be realized through its web service interface. In this way, the MRR is a service that can be accessed ubiquitously behind the scenes in a variety contexts, without users realizing it.
