How can I gather all the tag aliases

Hello people. It is necessary to make an tag-alias layer to keep my collection's tag database usable. How can I get this data?

What is a "tag-alias layer"?

If you want to know what aliases currently exist this page lists all ten thousand of them. You could write a script to use the api to more easily get a list of them onto your local computer.

OK, thank you.

It is for mapping the related tags without modifying the existing database, that is what I meant by saying layer.
