Centralised Data Infrastructure for Slavery and War
One query.
Every dataset.
"How can a centralised data infrastructure be designed to integrate, standardise, and enable analysis of heterogeneous data on slavery and war across space and time?"
PostGIS Elasticsearch Data Infrastructure Five-Layer Architecture
A unified query layer over dispersed, heterogeneous datasets with a four-step wizard and five-layer architecture spanning Classification, Time, Space, Actors, and Events.
Five-Layer Architecture
Each layer addresses a distinct axis of heterogeneity in slavery and war data.
01
Classification
Maps heterogeneous taxonomies to a shared ontology.
02
Time
Handles fuzzy, contested, and uncertain historical dates.
03
Space
Represents locations even when boundaries changed.
04
Actors
Identifies entities across aliases and spelling variants.
05
Events
Contextualises occurrences within broader narratives.
System Interface
CDISaW is in active development. Full data pipeline, classification matrix, and query wizard in progress.
