Let us break down your use case a bit more; right now we load and save a pr=

verything in the database? Or are you looking to "override" part =
of the normal load/save process and force some centrally defined styles ont=
o an already existing Map?</div>

when someone opens a layer (also saved in the database) they will be<br>
using the same style.<br>

<br>
There are a couple of aspects to what you are talking about. You<br>
mentioned making use of a database so I am going to take a couple wild<br>
guesses to try and figure out what you are getting at based on what<br>
others have done.<br>
<br>
The uDig load/save mechanism for Maps is all about saving this<br>
information into a project directory. In the past people have wanted to<br>
either:<br>
- save this information too and from a databases so users can work on a<br>
common set of maps<br>
- save this information too and from an Open Web Context document (to be<br=
>
<br>
attached to a wiki page)<br>
- save just the style information into a database and "update" ex=
isting<br>
maps to use the latest style from the common central database<br>
<br>
In each one of these cases you are going to get in there making your own<br=
>
<br>
maps and layers; taking charge of the process your application uses to<br>
assemble a working Map data structure for udig to draw. Let me know<br>
which one of the above scenarios you are working towards and I can try<br>
and make more specific recommendations.<br>
<br>
(the general idea is that these are just data structures so you can<br>
"load" and "save" them as you see fit)<br>
<br>
If I can ask you to review the IRC logs from this weeks meeting; Moovida<br=

<br>
requested a new "export style" extension point be created; it is =
not<br>
quite related to your request here - except in that it will represent<br>
another example of saving and loading a style to a file.<br>
