[webmap-discuss] Re: [Mapbuilder-devel] FW: [ka-Map-users] ka-Map and OpenLayers

[Paul Spencer]

Cameron,

At this point, there have been no design discussions.  The question  
on the table is whether (or not) ka-Map and OpenLayers should merge  
to form a single project.  The discussion on IRC and on the ka-Map  
mailing list so far has been directed at soliciting feedback from the  
ka-Map community about the potential merger.

The choice of prototype (for ka-Map) is based on my own experience  
using it.  I actually wanted to use Scriptaculous for an application  
(MapGuide OS Web Studio) and Scriptaculous is built on top of  
prototype.js.  I now have invested in learning it and am not really  
going to consider switching since I don't find it lacks anything I need.

OpenLayers is already using prototype.js - not sure what decision  
process lead to that, maybe Schuyler or Chris can comment.  In any  
case, it makes for a much easier migration from my point of view.

If there are compelling reasons to use another framework, I'd be  
interested in hearing about it.

There is a second discussion that needs to happen, probably on webmap- 
discuss, or the mapbuilder list.  This would concern how MapBuilder  
and OpenLayers (which in my mind includes ka-Map now) can work  
together.  There are substantial similarities and differences between  
the projects.  I think that OpenLayers could be used as the Map  
Widget in a MapBuilder application.  From a short conversation with  
Chris, it seems that you could use OpenLayers to manage both tiled  
and non-tiled map draws.  I think that has some interesting  
possibilities :)

The third discussion that also needs to happen on webmap-discuss is  
the issue of the proposed WMS-C standard proposal.  I am particularly  
interested in this as I can see the tile caching component of ka-Map  
forming the basis of a reference implementation of the proposed WMS-C  
and living as either a separate project or an optional sub-project of  
OpenLayers/ka-Map.

Cheers

Paul
