 The Project Open Data schema is case sensitive. The schema uses a camel case convention where the first letter of some words within a field are capitalized (usually all words but the first one).

-> Correct: `contactPoint`
-> Incorrect: `ContactPoint`
-> Incorrect: `contactpoint`
-> incorrect: `CONTACTPOINT`
+> Correct: `contactPoint`  
+> Incorrect: `ContactPoint`  
+> Incorrect: `contactpoint`  
+> incorrect: `CONTACTPOINT`
