<br>
This is a map schema I am using for map production in my geological survey. It
works fine for maps composed of only one map frame. I made some modification
trying to adapt it for a map with multiple map frames. The original program
that use this scheme was made using Arc-Info AML (I have some ideas to port it
to the next ARCGIS Python). This scheme does not include metadata and is a good
idea to include it.<br>
<br>
The idea behind of this scheme is try to give flexibility on styles and data
source management and re-use. It works fine for model based cartography.<br>

Hello everyone,<br>
<br>
I would like to try to get the ball rolling, so I thought to start simple. I'm
not familiar with Mapnik also, so please bear with me.<br>
<br>
What are the components of a map document (this are just informal ideas, give
your opinion about them :P)<br>
<br>
"Map Metadata"<br>
Author<br>
Date/time<br>
Subject<br>
Description<br>
<br>
Size (width x height)<br>
Graphics (north arrow, title, other pictures, etc)<br>
Ordered set of "views" (I'm calling a view what would be a map inset,
a map inside another map)<br>
<br>
Each "view" should have:<br>
<br>
Size of map-inset<br>
Extent<br>
Scale<br>
Projection (datasets have projections, but they
can be represented in a different projection)<br>
Ordered set of Layers<br>
[Coordinate grid] (each of these should be
graphic? should these be tied up to each "view" or they are
independent map graphics?)<br>
[Scale Bar]<br>
[Scale Text]<br>
[Legend]<br>
other elements I'm missing?<br>
<br>
Since XML was mentioned by <st1:City w:st="on"><st1:place w:st="on">Tyler</st1:place></st1:City>,
I tried a top-bottom approach.<br clear=all>
<br>
Any ideas about these?<br>
<br>
Thank you for your patiente :P<br>
<br>
George<br clear=all>
