project schema documentation
on this page
Dataset snapshot note (August 2026). Figures on this page derive from the wiki’s project dataset as it stood in December 2025 (604-609 tracked projects). That dataset has not been refreshed since, and the US pipeline grew substantially through 2026 — treat counts, investment and capacity totals here as a floor, and any share or percentage computed against them as approximate. Kansas and Missouri totals were separately corrected in August 2026 after seven Kansas City metro projects were found filed under the wrong state; see state rankings.
overview
this document provides comprehensive documentation for the data center project json schema used throughout the database. each project represents a single data center facility or campus documented with standardized fields for location, scale, timeline, participants, and sources.
