My starting work was using geonames but also thought about unlock
(unlock delivers geojson while geonames does not seem to ...)

geojson can include a title attribute i thought so we could store this
there. Alternatively, based on my experience in other projects, we can
have location-unparsed and location attribute.

Nice idea.
