If your site uses the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) 2.0 protocol, an application-independent interoperability framework based on metadata harvesting, you can use your OAI repository as your Sitemap .
Simply submit the baseURL of your OAI repository (for instance,
  https://www.example.com/oaiserver). When we query the baseURL, we automatically add query
  parameters (such as ?verb=Identify 
or ?verb=ListRecords 
), so you can
  simply submit the baseURL 
itself. When we extract the URLs for your site, we expect
  the records in the repository to be formatted using Dublin Core, with the URLs embedded in <dc:identifier> 
tags. Below is a sample record that includes the <dc:identifier> 
tag in bold. The URL listed in that tag is what we extract.
<oai_dc:dc xmlns:oai_dc="https://www.openarchives.org/OAI/2.0/oai_dc/" xmlns:dc="https://purl.org/dc/elements/1.1/" xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="https://www.openarchives.org/OAI/2.0/oai_dc/ https://www.openarchives.org/OAI/2.0/oai_dc.xsd"> <dc:title xml:lang="en">A title of extraordinary things</dc:title> <dc:creator>McCormack, Michael</dc:creator> <dc:subject>LCSH:Ausdehnungslehre; LCCN QA205.H99; Greatness:Amanda</dc:subject> <dc:publisher>J. Wiley ∓ Sons</dc:publisher> <dc:date>Created: 1906; Available: 1991</dc:date> <dc:type>text</dc:type> <dc:identifier>https://example.com/physics/1796949</dc:identifier> <dc:language>english</dc:language> <dc:rights xml:lang="en">Public Domain</dc:rights> </oai_dc:dc>
As with other Sitemaps, the URLs must be within the same site and at the same directory location
  or lower than the baseURL. For instance, if you submit https://www.example.com/oaiserver 
as the baseURL 
, the following URLs
  would be valid:
https://www.example.com/ https://www.example.com/samples.html https://www.example.com/images/
However, if you submit https://www.example.com/dataprovider/oaiserver 
, then none of
  those URLs would be valid.
