G?nter -

In some respects you are right. I believe the technology has still only 
scratched the surface. I have been working with distributed technology 
searching of museum data for a few years now and offer the following from my 
own experience:

As you know, museum data are different from library data in their level of 
uniqueness, complexity, physical attributes such as medium and technique, 
conservation data, exhibitions history, imaging and other attributes. The fact 
that the success rate or level of achievement falls short doesn't mean the 
technology should be dismissed. We should take a positive approach here, not a 
critical one. Other architectures also have their shortcomings, but that 
doesn't mean we should be shooting holes in them while those pursuing them work 
on making them useful. All of the items you have cited could be problems from 
your point of view. That is fine, but your points are a bit near-sighted. Just 
because Star-Trek-level, multi-lingual, thesaurus assisted, ranked, easily 
discoverable (without harvesting), near-real-time updated database searching 
hasn't been achieved yet through distributed means should not imply that it 
can't eventually do all those things.

In an attempt to not lose sight of the original project, Chuck's comment is 
also important. There are probably a lot of regional, domain specific groups or 
other affinities that could benefit from distributed technology today and can 
take advantage of it as is.

Based on this thread, I would like to invite any museums/individuals interested 
in participation in distributed searching to get in contact with me. We are 
forging ahead with our eMuseum Network project. I believe a cooperative effort 
between Gallery Systems' eMuseum Network project, Stephen's MWeb project and 
other such projects are worth pursuing.

Best regards,

Jay

Anything that moves us closer to a methodology for making unified discovery 
across different collections a routine reality is worth celebrating. I 
wholeheartedly agree with Chuck on that vision, and am delighted to see what 
MWeb has done, and much looking forward to future developments Jay hints at. 
These projects and products demonstrate the immense power of bringing data 
together, and hopefully will motivate the museum community as a whole to take a 
long hard look. If federated search turns ou??t to be a useful tool to 
achieving the vision of searching across many museum collections at a time, I'm 
on board.

At the same time, I think it is also worth having a look at what others who 
have pursued this path have to say. Here are some of the main issues with 
federated searching as gleaned from the library experience with it. At first 
glance, these seem to apply in a museum context as well.

* You usually have to wait until all targets respond, so your wait-time for a 
search result can be fairly long in a federated search.
* You usually only receive a specific subset of records with hits from each 
target at a time.
* Since you only have a subset of actual records with hits in hand, you are 
fairly restricted in your ability to offer faceted browsing.
* You usually have to depend on the ranking the original target provides you, 
and to harmonize rankings between results from different targets is a 
challenge. To put it simply, it's difficult to assess whether the first hit 
from database A is as important as the first hit in database B, or whether the 
first 5 hits from database A are much more relevant than the first hit from 
database B. That means you are usually restricted to just show hits segregated 
by the different databases, not integrated into a single run-on search result.

In the UK, the national museums and galleries have just launched Creative 
Spaces (http://bm.nmolp.org/creativespaces/), which also relies on federated 
search, and there have been discussions about the pros and cons of federated 
search in that context as well.

I'd be happy to learn more about how these issues can be addressed from Stephen 
and Jay. For those who have the patience to wade into another community's 
discourse to learn lessons for our own, I'll recommend this article by Jonathan 
Rochkind, which gives a good background to what I've tried to summarize above:

I agree with Jay. And let's not forget that the market this demonstration
piece (PastPerfect users) showcases is one where federated search is
something both truly unusual and highly beneficial given the frequency with
which these collections are small and not easily accessible.
