The Collaborative for Historical Information and Analysis (CHIA, formed 2011) links academic and research institutions in North America and Europe—with ties to institutions in Africa, Asia, and Latin America. CHIA’s key contributions are data linkage (for data analysis in general) and a global archive (to permit historical analysis on a global scale).
The long-term purpose of CHIA is to sustain a Human System Data Resource, linking variables to analyze many areas of human experience.
CHIA has three basic structures. Global Data Submission (GDS) incorporates data, relying on Data Hoover to “sweep up” data but also survey data holders and evaluate incoming datasets. World-Historical Dataverse (WHD) is the public archive of CHIA, a curated set of datasets, preserved and documented on the Harvard Dataverse archival platform (Level 1 documentation). The Human System Data Resource (HSDR) links datasets, relying on documentation of datasets, supported by the Col*Fusion infrastructure. (Level 2 documentation). CHIA circulates datasets through GDS, WHD, and HSDR until they contribute to multi-scale analyses.
CHIA builds and tests theory. It creates robust ontologies to facilitate data linkage, then CHIA has chosen global inequality as a key topic for building global historical analysis.
