Generalizing the IRI plugin
• Currently entities are a view plus
(optionally) a set of local data views
– Local view is click-on-map plus some
parameter choices
– Would be good to generalize those parameter
choices
– Parameter choices should only appear when
appropriate
Generalizing the IRI plugin
• Currently entities are selected from a
cascading menu
– IRI should serve that menu
– Menu should be generated in a meaningful
way
– Do we need to consider some other way?

Generalizing the IRI plugin
• Making better use of WMS
– Should separate out the layers
– Transparent Background on Images
– Could include local info references within
