SCIM resource modifications are performed using a PUT operation returning the entire profile with the changes applied. For example, to add a "title" to Meredith's record I will take the contents of a GET request, add in the title attribute and PUT it back to Meredith's User resource location. 


curl -v “X PUT --user 1234-aaaa-bbbb-5678:eXJzbmVha3kh \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-d '{
