[Tagging] OpenPlaques

[Andy Mabbett]

We should merge:

   Key:openplaques_plaque (27 instances)

and:

   Key:openplaques_id (293 instances)

while the latter is more widely used, the former is less ambiguous, as
OpenPlaques also has IDs for people and venues.

Do we have a process, or preferred venue, for for discussing such matters?

If we do decide on the "_plaque" variant, how do we discourage
colleagues from using "_id"?
