OpenStreemap ?

Today you can do like this
joomla.zhuk.cc/index.php/zhgooglemap-mai...gm-plugins/gm-geotag

ie icon, clicking on it - go to native map and passing into it coordinates.
ie there is no map in article, only link.

Probably, if use iframe it can be done, but I don't think by text address. By coordinates. For example for Google probably you can pass address, but I don't know is it can be done for OSM, by coords or address. It needs to read more.

Not sure to understand all you wrote but ok

To understand why i ask this : in a site, i have several peoples (each in one article) and the people have an address.
The goal is to show the map with their location. I cannot create a map for each people as people type their address by their own and the map should be shown automatically on the basis of this address.
So, in example, people use 3 customs fields : address, Poscode, City, and this is used to generate the map (like the old "Mosmap").

I dont know exactly how to achieve this with OpenStreetmap.. If you have an idea on how i could do this, please tell me

Have a nice day Dima
