Sure,
We're aiming for consistency with our public APIs so that:
1) Collections are handled consistently
a) Pagination works the same across APIs
b) Filtering works the same way across APIs
2) URIs are built in the same manner
a) Versioning is handled the same way
b) URIs follow a consistent pattern
3) Error conditions are handled consistently
a) HTTP error codes are mapped in a consistent manner
b) Error info is return in the content of the message in the format
4) Special features should be included in every API and handled consistently
a) Queryable Rate Limits
b) Changes-since operations
5) Authentication/Authorization...
6) Polling operations and events...
etc...
This kind of worries me. Lots of this stuff is going to vary between services,
and I think we need to leave plenty of room for APIs to be informed by their
domains and implementations.
Something like pagination may seem like we could standardize across services,
but the Swift and Cloud Servers APIs already use completely different methods
for paginating. Probably for good reasons on both sides.
We can always make exceptions if there's good reason for it -- let's have those
conversations as they come up.
I see standardization as being extremely beneficial. Having a common language
framework is one example of how standardization can help us, but it's important
to also think of this from the perspective of our clients -- why should they
have to learn 10 different ways of doing the same thing?
