  Every file in this tree is made available under the Open Database License (ODbL) 1.0, https://opendatacommons.org/licenses/odbl/1-0/
  The pew layer and the OSM layer below are kept in separate files, but together they form one
  database under ODbL 1.0. You may copy, share and adapt it, including commercially, as long as
  you credit the sources named below, keep the result under ODbL, and offer any adapted database
  you publicly use under ODbL too.

PEW LAYER: dioceses/*.json, reference/*.json
  Licence: ODbL-1.0, https://opendatacommons.org/licenses/odbl/1-0/
  Parish, worship-site and Mass-schedule data collected by Pew Companion from parish and diocesan
  sources. Contains no OpenStreetMap data and no OpenStreetMap identifiers.
  Attribution: Pew Companion parish data (desk research from parish bulletins and websites), ODbL 1.0.
  Provenance is abbreviated in these files (provenanceForm "slim"): each record keeps its source
  kind, source URL and date, when a person last verified it, the kind of verifier and a confidence.

OSM LAYER: osm/*.json, osm/crosswalk/*.json
  Licence: Open Database License (ODbL) 1.0, https://opendatacommons.org/licenses/odbl/1-0/

  Derived from OpenStreetMap: Catholic places of worship and candidate service times.
  osm/crosswalk/*.json pair Pew Companion site ids with OpenStreetMap objects, so a client can
  show OpenStreetMap positions for Pew Companion churches. Data joined that way is a Derivative
  Database of OpenStreetMap, under ODbL 1.0.

ODbL 4.6: these files are the complete database the Pew Companion app uses, published here in full
and free of charge.
