Hello again, Bruna,
What you have included in Metadata Manager is the URL where users can retrieve the license that pertains to the text and data mining. The “Text Mining URLs” section of our Participation Reports measure something related, but a little different - the full text URLs where that text and data can be mined. You can find more about the difference between the two and instructions on how to provide the full text mining URLs via XML here: https://0-support-crossref-org.library.alliant.edu/hc/en-us/articles/214298866-Full-Text-URIs-Technical-Details
To support text and data mining, publishers need to update their metadata to include full text URI(s) for each piece of content with a DOI. Anybody using the CrossRef Metadata API to query a CrossRef DOI will be able to retrieve these URLs and follow them directly to the full text. Publishers who want to be able to support multiple “representations” of the full text of the article will be able to do so. So, for instance, they could support the delivery of either PDF, XML or HTML, or just one of these formats.
Included in that link I provided are two XML sample files which you can follow to submit your full text mining URLs.
Please let me know how I can help,
