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.

XRDS (Extensible Resource Descriptor Sequence) is an XML-based file format that provides a list of service endpoints (e.g., OpenID) available on a website.
