I want to use the metadata tags in our sharepoint portal application. This should not be hard coded and need to be based on pages. The user should be able to search based on metadata tags. How can we do this without hardcoding ? Please suggest a best way to do this.
EDIT
I want to tag the metadata keywords in the pages, so that the user will be able to search based on that. I think the can be used for that purpose, but I don't want to hard code the keywords. These keywords may be configurable and hence need to store outside the page. I hope this will give an idea about what I'm trying to achieve. (I have heard about managed metadata, but don't know much about that. Does that serve my purpose ?)
