Gaia Catalog

Description

A readily-extensible catalog of source datasets. Gaia Catalog contains metadata for public geospatial datasets. Descriptive metadata facilitates search and discovery of relevant datasets. Functional metadata (machine-actionable instructions) enables automated retrieval, extraction, transformation, and loading of public datasets and their constituent variables.

Scope

The ultimate vision of Gaia Catalog is a web-hosted repository where users can access and contribute functional and descriptive metadata for public datasets to facilitate their standard use across networks and beyond. Currently, the data for still-developing catalog is contained in the OHDSI GIS WG GitHub Repository:

Resources

The data_source.csv file contains information on public datasets.

The variable_source.csv file contains information on the variables contained in those datasets.
