Looking for theme with POIs in a special format

Hello,
I’m looking for a theme where I can mark points of interest. They will be shown on a map. When selecting one, information with links have to be shown. One part of the information is specific for that one POI, the other part is one text out of several predefined. Each POI can have just one on these predefined texts. Predefined texts can be shown on multiple POIs.
Does anybody know a good theme for it?
Thanks, Ralf
