CSI (Construction Specifications Institute) stewards and governs MasterFormat, UniFormat, and OmniClass. Public pages provide orientation and workflow guidance; authoritative numbers, titles, hierarchies, edition history, and governed crosswalks are available through licensed CSI Dynamic Standards access. Use each page's canonical URL as its identifier. Entity reference pages identify their parent standard with schema.org DefinedTerm and DefinedTermSet markup. Commercial access information is separated from public explanatory content. Public guide scope and terminology are reviewed against CSI's published standards information. These pages are orientation resources and do not reproduce or replace the licensed standards. ## Official CSI Sources - [CSI Standards overview](https://www.csiresources.org/standards/overview) - [CSI MasterFormat 2026](https://www.csiresources.org/standards/masterformat2026) - [CSI About UniFormat](https://www.csiresources.org/standards/uniformat/about-uniformat) - [CSI About OmniClass](https://www.csiresources.org/standards/omniclass/standards-omniclass-about) -
