+2446 churches designated as “Church of England” 
+2476 Catholic Churches
+3584 Methodist churches.

+So why does all this matter? There are two key reasons why scholarly focus on these data sources might align well with our concern for public literacy about religion and frankly justice. First, for many people walking around in Europe, these data sets are reality. When was the last time you navigated somewhere without using a turn-by-turn app on some smartphone? If data is lacking in completeness, these places simply fall off the map. Second, is metadata. While this term may seem fairly innocuous, it can be a very malevolent force. Metadata is simply the practice of adding a bit of additional data to the 'main stuff'. So we have some coordinates and a name for a place of worship, and then maybe we add the opening hours, or we allow people to add ratings, or we add a category.

+### Exhibit A: All of Google's religion categories:

+- .strikethrough[place of worship]
+- church
+- hindu_temple
+- mosque
+- synagogue

+### Exhibit B: Schema.org Microdata Specification

+["developed by an open community process"](https://schema.org/)
+
+Place / CivicStructure / PlaceofWorship subcategories (v3.4):
+
+- BuddhistTemple
+- CatholicChurch
+- Church
+- HinduTemple
+- Mosque
+- Synagogue
+
+???
+These categories produce borders and tacitly facilitate exclusion. Have you ever wondered how google finds content based on a given search you produce?
