[OpenLayers-Dev] WMC on WMSManager

[Lorenzo Becchi]

Nothing to be proud of but I've published a first step to support Web 
Map Context inside OpenLayers:

Click on the bottom-right button "WMC Exporter" to see a pop-up with the 
JSON code of the WMC.
Naturally you can alter the map with WMSManager and the WMC "should" be 
updated.

as you can see:
- the structure is not a perfect WMC. I've took a look from the 1.1 
specs but there are things to be cleaned up.
- some values are empty or null. Still have to decide if it make sense 
to use all of them. We can decide together which optional elements not 
to support.
- I've added a "visibility" attribute to Layer object because WMC is not 
providing it. Some hint how to avoid this? I'm sure you understand how 
this is important for OL to define base or overlay layers.

as you can't see:
- not all values are dinamically set. Some are still hardcoded.


there's another problem about attributes of Layers with multiple WMS 
layers inside. Which title, abstract to use? does it make sense to 
create a comma (or something else) separated list of values?


I'm still not sure if the MapContext should be part of the OL.Map object 
or an external Tool.
I'll go on with the external tool and hope to create soon a WMCParser to 
import WMCs.


My hope was to offer something better before leaving for holidays but 
many meeting/debate/ecc at work delayed coding time.
I'll leave in 2 days and be back for the third week of August. In the 
meantime I'll be available for debate about this solution.

ciao
