A re-usable list of Roman Amphitheaters. Currently formatted as geojson with a json-ld context. It's very incomplete as, depending on how you define the term, there are some 200+ amphitheaters known from the Roman world.
Some of this data comes from Wikipedia's list of Roman amphitheaters at http://en.wikipedia.org/wiki/List_of_Roman_amphitheatres . I used that as a starting point but have made corrections.
The basic json object for a "record" is:
{ "type":"Feature", "id":"arlesAmphitheater", "properties":{ "title":"Amphitheater at Arles", "wikipedia":"http://en.wikipedia.org/wiki/Arles_Amphitheatre", "created":90, "capacity":20000, "location":"http://pleiades.stoa.org/places/148217#this", "rdfs:seeAlso":"http://pleiades.stoa.org/places/148217/location-of-roman-amphitheater" }, "geometry":{ "type":"Point", "coordinates":[ 4.631111, 43.677778, 21 ] } }
If you want to load this file into a geojson-aware mapping tool, use the URL:

And a turtle version is at this URL:

As a convenience, here's a link that validates the geojson in the above file:
And here's an example of running the geojson through Greg Kellogg's online distiller:
What's the purpose? To explore reusable data. If it becomes a complete list of amphitheaters, that's a pleasant side-effect.
