[OpenLayers-Dev] auto-generating OpenLayers javascript

[Burgholzer,Robert]

Tim,
My thought is that for the initial crack at this, all I need to be able
to do is to create an easy to use plugin for WordPress, that ASSUMES
that the user can generate some OLON code.  This is not a problem for
testing purposes, and can be a place-holder for such a time as I find
some sort of standardML that can make it more universal (shoot, for now,
OLON seems to be the most universal).  This will at least allow ME to
play around with this stuff, basically, including my OL maps in blog
entries.

So, this brings me to the code. I am having trouble getting your example
to work.  When I do as you say on the page, navigate, hit "save state" I
get some OLON code, but when I refresh my browser, it returns to the
default view with "no state saved".   I don't think that I have cookie
trouble, but who knows.  (Firefox 2.0.0.14).

More importantly, since I implicitly trust that your code works, where
do I find the OLON stuff in the libraries?  And, does the method
"deserializeMap(str)" automatically assume that the map div is named
"map", or is there some directive that I am missing somewhere in your
example code.

Thanks!

Hey-

As Bart mentions, WMC is the only spec that comes close to this (but as 
he says, just for WMS layers).  The OWS Context spec is not yet adopted 
as an OGC spec (http://www.ogcnetwork.net/context).  When it is, we can 
write a parser for it.  However, this would still not treat things like 
a Google layer, or a Vector layer with a few hand drawn features, or a 
map with an overview map control.

If you really want to serialize things specific to OpenLayers, then you 
probably won't find a standard.  A while ago, we started work on an 
OpenLayers object notation (OLON).  I put together some stuff that would

allow objects created from OpenLayers classes to be serialized as OLON -

and then be deserialized again as instances of the same classes.

You can see an example here:
http://dev.openlayers.org/sandbox/context/examples/olon.html

This may be overkill for what you want - WMC or OWS Context are 
certainly more "standard".

This also would take a bit to get in to the trunk - so really just a 
heads up.  If you're interested though, it would be good to know that 
there is interest in it.
