- Thread-topic: [xml-dev] R: [xml-dev] Number of active public XML schemas
[Jumping in at a random point in the thread]
In the US federal space, the following site has just been made publicaly available for the registration of XML schemas and other XML artifacts:
https://xml.core.gov/
This is part of a site called Core.gov, which is run by the U.S. General Services Administration (GSA). I am not certain of the rules/policies for registration and discovery (as I am personally not directly involved with the project), but I understand it requires a login. I wanted to offer it up as an example of a place where one could see schemas registered in the future.
Kind Regards,
