[Geoprisma-dev] Time frame/estimate to implement these features

[Yves Moisan]

Hi All,

I guess we've all been rather busy with our day to day lives to the 
point of not doing much in terms of thinking about a new round of 
features for GeoPrisma, so please allow me to begin a new one, with the 
features people come to me and ask for ;-).  What I'd like at this point 
is a rough estimate of the time it would take -- and potential issues -- 
related to the development of the following points.

1) Feature and WMS filtering (http://trac.osgeo.org/geoprisma/ticket/38)

One recurrent wish is for integrators to be able to easily filter what 
is presented to users looking at the map as a function of some role.  
That is, both users can view the same layer, but only features in a 
specific location and/or filtered by some attribute.  For GeoPrisma, 
this essentially means two things :

- Make the shortcut and MapFishRecenter tools (and any future GeoPrisma 
widget that will provide a dropdownlist of choices) be aware of 
filtering so that choices are dynamically filtered by user role

- Provide adaptive map extents (restricted or not) and filter WMS results

For the first point, I think we can use FeatureServer's filtering 
capabilities at least on text fields (|?queryable=...).  |capabilities.  
I've seen issues with numeric filtering (like <= and >= working 
separately, but not together) but overall I think FS can serve us well 
to filter dropdown lists.  My guesstimate to implement the required 
functionality in GP (e.g. url parameter passing) is 2-3 days.  If we 
really need numeric filtering, then maybe setting up a new MapFishServer 
service would be an option.

For the second point, I'd like to have a guesstimate from you list 
readers.  The adaptive map extent problem can be solved by a workspace I 
believe.  To filter the WMS request, I don't know.  I gather the WMS 
spec does not allow for passing in parameter filtering in the request, 
but MapServer supports FILTER/FILTERITEM, so I don't know what that 
means for GeoPrisma.  Comments welcome.

|2) QueryOnClick with HTML content 
(http://trac.osgeo.org/geoprisma/ticket/10)

See description of the requirements in Trac.  Time to implement =  ?

Let's start with that for now.  So what are you thoughts/time estimates 
for those ?

Cheers,

Yves
