Resources, not Objects

Keyur, you must think in terms of resources, not object methods. Nouns, not verbs. In a restful architecture you don't cause your person to talk, you listen to the person's words:

GET /persons/1

or, if you want to be fancy:

GET /persons/1/words

Likewise, you don't cause them to walk a step, you update the person with a new location:

PUT /persons/1
{ ..., "location": [[-100.0, 40.0]] }

or:

PUT /persons/1/location
{ "location": [[-100.0, 40.0]] }

Matrix URIs? They're standard with Rails, but mainly to allow PUT operations to tunnel via POST from dumb clients like the browser:

POST /persons/1;edit
{ ..., "location": [[-100.0, 40.0]] }
