Description

The ISO 19111 model contains at least 3 metadata elements from ISO 19115-1: Citation, Extent and PositionalAccuracy. A JSON encoding for metadata is being defined as ISO/AWI TR 19115-4 – MetadataPart 4: JSON schema implementation of metadata fundamentals (currently under development). If a standard metadata encoding is defined, we may want to avoid inventing another standard inside CRS JSON. We may also consider defining other CRS elements using the same pattern as ISO 19115-4 for consistency.

ISO 19115-4 is not ready yet, but progress have been reported during the OGC meeting at Montreal. We may use the current state, and update the CRS JSON draft as needed when ISO 19115-4 draft changes.

Research direction

No repository file or test is named. Start by reviewing the current CRS JSON draft and the linked ISO 19115-4 work, then determine whether Citation, Extent, PositionalAccuracy, and other CRS elements should follow the same metadata pattern; done means the project has an agreed consistency decision and an updated draft if needed.
