| General principles for good URI design: | |
| Don't use query parameters to alter state | |
| Don't use mixed-case paths if you can help it; lowercase is best | |
| Don't use implementation-specific extensions in your URIs (.php, .py, .pl, etc.) | |
| Don't fall into RPC with your URIs | |
| Do limit your URI space as much as possible | |
| Do keep path segments short | |
| Do prefer either /resource or /resource/; create 301 redirects from the one you don't use | |
| Do use query parameters for sub-selection of a resource; i.e. pagination, search queries |
