About
OpenSearch is a specification that describes a website's search engine, enabling browsers, apps, and services to discover and integrate it.
It is implemented as a linked 
XML file and was originally developed by Amazon to make it easier for other applications to integrate their search services.
Really Simple Discovery (RSD) is an XML format that helps client software find the services needed to read, edit, or "work with" weblogging software.
