So here it goes - it is hosted by the SETDA working with CCSSO, PARCC, SBAC and NGA to create the GIM-CCSS
“Granular Identifiers and Metadata for the Common Core State Standards or GIM-CCSS) will facilitate the long-term technical implementation of the Common Core State Standards (CCSS) in a digital format that meets the diversity of stakeholder needs in the field, while preserving the conceptual and structural integrity of the standards.
While CCSSO and the National Governors Association (NGA) Center for Best Practices have developed a foundational digital identifier structure for the Common Core, a more fine-grained digital mapping is needed to fulfill the goals and objectives of the multi-state assessment consortia, as well as for other purposes including the digital alignment of instructional materials and professional development resources."
