Schema Themes

Themes are top-level categories of map features. A theme may have multiple types of features, for example, the Transportation theme has both segments and connectors.

Core Concepts

Internal Consistency

Where applicable, fields such as "address" or "name" will always use the same schema across all themes.

Extensible attributes

Any additional top-level property prefixed with ext may be added to a feature.

Stable IDs

The Global Entity Reference System is responsible for handling persistent identification across entities on the map.

Note: The id present in examples in this documentation is not demonstrative of the final format of the GERS ID.
