From their site: A lightweight service for handling a user's personal media assets, such as photos. Users with a MediaSock compatible client application simply enter a server domain and the client discovers the available methods without the need for the user to select from a confusing list of APIs or URLs. MediaSock draws on the workings of existing private APIs and related public APIs in use by web-service providers, and it is intended to work alongside the methods provided by them. It is not a wide-ranging specification but a guideline for minimum interoperability, with ease of implementation by services and ease of use for consumers.
The following is a list of SDKs from our SDK directory that matched your search term. Though your definition of an SDK may differ, in our world, we define SDKs as platform- specific tools for consuming existing APIs of the sort we list in our API directory. For example, the Ruby SDK for consuming the Twitter Ads API. If you think an SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
