How to find all Pleiades URIs that correspond to a Trismegistos place URI

findit.py

# read in the json and get the graph of places
import json
with open('pleiades-places-latest.json', 'r', encoding='utf-8') as f:
    pj = json.load(f)
graph = pj['@graph']

# iterate through the graph and test each place for a TM reference
for place in graph:
    references = place['references']
    tm_geoids = [r['accessURI'] for r in references if 'trismegistos' in r['accessURI']]
    if len(tm_geoids) == 1:
        print('{} = {}'.format(place['uri'], tm_geoids[0]))

Python 3.6. This code assumes that you have already downloaded the Pleiades comprehensive nightly JSON export from http://atlantides.org/downloads/pleiades/json/pleiades-places-latest.json.gz and un-gzipped it in your working directory.

Output will look like:

https://pleiades.stoa.org/places/265876 = http://www.trismegistos.org/place/27183
https://pleiades.stoa.org/places/265880 = http://www.trismegistos.org/place/27402
https://pleiades.stoa.org/places/265886 = http://www.trismegistos.org/place/27107
https://pleiades.stoa.org/places/265887 = http://www.trismegistos.org/place/27479
https://pleiades.stoa.org/places/265891 = http://www.trismegistos.org/place/27788

missing parenthesis on line 12 to close the print command

    print('{} = {}'.format(place['uri'], tm_geoids[0]))

Thanks @fosco13! I've updated the gist.
