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.
