I have been experimenting with interfacing between the Minnesota Map Server software and Greenstone; links to Greenstone pages are fairly straightforward conceptually; tieing a Greenstone item to the map is trickier. In our project we don't have precise spatial coordinates for lots of data in our initial data so we have to add them; if they already existed in a known coordinate system it would be fairly easy to create a call to MMS to show the area in question.

Postgres was likely to be our database of choice as it works well w/ MMS (and I am heartened to see in another response to your mail that the GSDL perl DB interface works with postgres) so I can't much advice on SQL server (although I have seen MMS posts that indicate that it can be made to work with MMS).

I'd be glad to lend whatever (semi-skilled) labor/ideas I can.

Subject:[greenstone-devel] appropriateness for a land database
Aloha,

I'm very impressed with the use of Greenstone for the Hawaiian
Electronic Library (ulukau.org). However I'm wondering if Greenstone
can be programmed to be both an independent database AND portal to other
sources.

I've been assigned the task of developing a database including digitized
resources, i.e. leases, photos, etc and existing databases. One existing
database is of GIS data compiled and managed by MS' SQLServer. The tool
I select must allow users to link easily from citations to full-text
content. Is Greenstone appropriate for compiling such data and
executing a cross database search? Looking at some examples from your
webpage, it does appear to go beyond searching the individual digitized
collections but I wanted to confirm.

When retrieving data, can Greenstone determine relevance? Is there an
algorithm for this?

I'd like to be able to import MARC records (I have yet to decide if I'll
use MARC or Dublin Core as the base protocol).

Mahalo for your time and consideration on these questions.

Aloha piha,
