Metacat

This is a utility class for generating a pathquery document from an array of docids that one wants to query for. Its hacked together in that the default query parameters are all hardcoded into the class, which is obviously wrong. Need to figure out where those default params should be derived from.

Integration of new shapefile writers (r. reeves code) with MSO.

Continued integration of the spataial stuff with the metacat servlet.

Integration of the metacat servlet with the spatial option -- rubberbanding is implemented too.

Implementation of the rubber-bad query that PMARK has implemented through the UI.

metacat spatial option code -- code that produces layers depending on the
