Describing data in a common language improves accessibility, interoperability, and reusability. Historical demographers have designed their own schemas and vocabularies to standardize historical data. CLAIR-HD gives an overview of these standardization tools, so that historical demographers can model their data using existing terminologies.

CLAIR-HD was funded by the NWO.

Schemas

Standardize all variables in a database to make information from different data sources comparable. There currently is no dominant schema in historical demography.

A data model schema diagram featuring interconnected circles and labels. At the center is an orange circle labeled schema:ArchiveComponent. From this central node, three arrows point downwards to other elements: An arrow labeled schema:locationCreated points to an orange circle named schema:Place. An arrow labeled schema:additionalType points to a blue circle named pico:huwelijksakte (marriage certificate). An arrow labeled schema:dateCreated points to a grey circle named xsd:date. At the top, a purple a

Vocabularies & Variables

Standardize entries, group them, or assign status codes to historical phenomena. Occupational schemas are by far the most standardized.

Vocabulary Page

Conversion tools

These are coding tables that transform vocabularies, for example, standardized occupational titles into HISCO or HISCO into status codes.
