Extensions: Identifiers

[m-mohr]

There are various identifiers that people use. For specific types of identifiers individual extensions should be created.

Examples:

• Varda Field ID
• INSPIRE IDs ( https://github.com/fiboa/inspire-extension )
• FLIK ( https://github.com/fiboa/flik-extension )
• ...

How do we handle he following case:

• Original dataset doesn't provide an "id" field
• Original dataset provides a field "flik", which is an "id"
• Fiboa asks for an "id" field and there's a "flik" extension that asks for a field name "flik"

How to handle this? For now I'm just duplicating the columns in GeoParquet and GeoJSON, they have the same content. In GeoParquet I just hope that Brotli compresses the values good enough.
