Back to spatial coverage: unfortunately there are at least three respectable serializations of geometry in common use in different parts of the community:
- WKT - originally from OGC, now built-in to the Postgres extension PostGIS, and also used in [GeoSPARQL](https://www.opengeospatial.org/standards/geosparql)
- [GeoJSON ](http://geojson.org/) - which uses nested JSON arrays
- [schema.org/GeoShape](https://schema.org/GeoShape) - which uses a single space-separated array of coordinates

AFAIK WKT is the only one that also supports association with a [Coordinate Reference System](http://docs.opengeospatial.org/is/12-063r5/12-063r5.html)

Then there are others, like GML, What3Words, ... 

The [Spatial Data on the Web Best Practice](https://www.w3.org/TR/sdw-bp/#describe-geometry) is agnostic ... Should we attempt to provide any guidance?
