Yes, you can access blobs too. I've been using the HTTP API (the one that backs CloudKitJS) to process data in app engine. So far I just used the JS API token for authentication. Records with an associated blob asset provide a temporary accessible URL to the asset which is usually stored on S3.

Not sure about latency of the requests, never had a problem with that. More often the problem was that I had confirmation my client software had written data to CloudKit but it might take a while before the server can actually query for it. (Could be an indexing delay haven't checked if the object is immediately available using the object ID)

Which is based around a HTTP API (also documented by Apple). Not that hard to wrap that in an easily usable SDK for other platforms.

Question is: what license is that work released under (GPL3?) and does that license require attribution?

Unfortunately not this year :(

Cool. Feedback is always appreciated.

I'm also collecting interesting compositions for demo & test purposes. So anything you're able to share might help me implement the required patches.
