From their site: Tucows Feedcache is Quality of Service for RSS. It is designed to make syndication formats more available and more predictable for developers. Tucows Feedcache: Developer Edition provides a web services interface to a user-populated cache of RSS feeds that developers can use and implement in their applications. Tucows initially developed Feedcache for internal use only, but really didn't see any good reason why such an excellent service should be kept under wraps.
The following is a list of libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
