The NBIMS-US™ v4 is a consensus-based national-level standard focused on defining standard approaches and guidelines to defining requirements, planning BIM adoption, and exchanging information between project team members. MORE
IFC Tables A, B, and C are intended to direct the reader to the most relevant pages of the IFC4.3 documentation:
http://ifc43-docs.standards.buildingsmart.org/
The COBie3 MVD and IDS contain the formal definitions.

SPREADSHEETML FORMAT
ISO/IEC 29500-1:2016
SpreadsheetML is an XML schema reflecting the organization of spreadsheet data in Microsoft Excel. The use of SpreadsheetML format for COBie data is optional in this specification. The SpreadsheetML format represents COBie data in an easy to understand and digest format (human readable).
More information on the SpreadsheetML schema can be found here:
https://learn.microsoft.com/en-us/office/open-xml/structure-of-a-spreadsheetml-document
An example blank spreadsheet is included as part of this standard.
