Thanks a lot.
I will take a shot since this has been hanging since this morning. I admit I didn't respond this morning because I am not quite sure what you are asking. You can dynamically include meta tags on seperate pages a number of ways with a number of languages.
With php I have called them from a database, Included seperate files for each set of tags, had a big lump of tags on one page and read the pagename to know which set to put on the page. I am sure I have used other methods as well but can't think of them off the top of my head.
Is this what you are asking? If not maybe you can give us a little more specific info and I, or someone else, can maybe give you a better answer or one that is tailored to your situation.
Do you know what I mean?
