[mapserver-dev] Advanced Selection Management API

[Paul Spencer]

We have a customer for which there is a need for some more advanced selection management functionality.  The basic requirements are:

* create a new selection from a set of features selected spatially or by some combination of attributes
* save a named selection (serialize to disk file)
* restore a previously saved selection (deserialize from disk file)
* modify a selection by adding or removing features selected spatially or by some combination of attributes
* highlight a selection when drawing using the CGI (like referencing a .qy file)
* access features in the selection for other aspects of the application

My questions:

1) is this achievable with the current setup?  I don't think so, the only way I can think to do this is to use mapscript to create shapefiles of selected features and manage selection as separate datasources and layers

2) is this something that would be desirable to have in mapserver/mapscript or should I just look at doing my own thing on the side?


Cheers

Paul
