OpenSearch
SitemapType
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.
A sitemap is a specialized XML file that lists a website's URLs and helps search engines discover pages available for crawling and indexing.
It can contain metadata such as last modification dates, update frequency, and page priority, supports extensions for images, videos, news, and multilingual pages, and is typically referenced through the <link rel="sitemap"> 
HTML element or the robots.txt file.
