custom component - transforming post/thread tags in meta-tags

Hi,

I am trying to create a custom component that would transform tags defined on posts & threads in meta tags to be added on the page results.

Has anyone tried that already and how does it works?

Would you share your source code to the community?

At the same time, why Lithium does not automatically add the tags in the meta tag section of the page?

Thanks!
