You can get the Language Bank’s metadata in a machine-readable CMDI format by using the MIME type application/x-cmdi+xml. Note that this method works only with a URN or Handle, not directly with a META-SHARE link.
For example:
curl -L -H "Accept: application/x-cmdi+xml" http://urn.fi/urn:nbn:fi:lb-2020021801
This returns the metadata presented at http://urn.fi/urn:nbn:fi:lb-2020021801 in CMDI format.
