Pia,
Unfortunately I don't have time to consolidate my thoughts into a decent
paper before Monday, so you will have to do with a few random scribbles.
I wrote a paper about a year back assessing Australia's investment in
Geonetwork, the Open Source Metadata tool, and by providing
recommendations in how to move forward.
The full paper is here:
http://cameronshorter.blogspot.com/2009/05/strategic-geonetwork-investment.html
I think you will find it an interesting read, but the key message you
will probably be looking for is in the section: "Open Source Spatial
Data Infrastructure":
/“… a key funding challenge faced by Spatial Data Infrastructure (SDI)
programs is that while sharing data in a distributed SDI reduces the
overall cost for everyone, not everyone is equally better off”./
/ For data custodians, publishing data is a cost centre and doesn’t
provide a substantial business benefit. /
/ Many, including Ben Searle from the Australian Government Office of
Spatial Data Management, realize that:/
/“… an effective way to increase access to other agencies’ data is to
sponsor free, *Open Source tools which will reduce the cost barrier to
sharing data.*”/
---
Basically, Government investment in Open Source tools is an incredibly
effective funding vehicle for developing a SDI.
The excellent news is that robust Open Source tools already for the
publishing and sharing of geospatial data (geoserver, mapserver,
tilecache) and metadata (geonetwork), and these tools are widely
supported by an international community.

There is also an excellent study, well known in the Australian SDI
industry stating the value of Australia investing in Spatial Data
Infrastructure:

We need to ensure that standards are complied with. We have a situation in the emergency management space where an un named department is merging two metadata standards to create a 'new' standard. This will be Australian only 'standard' that will not be supported by any software vendor.

Melbourne university did a review of Metadata tools on behalf of the
Australian and Land Information Council (ANZLIC) a couple of years back,
and recommended that Geonetwork be selected as the tool of choice.
Geonetwork is standards compliant (implementing on the OGC Catalog
specification) and provides both a catalog server and browser based client.
The client is very powerful, but is not very user friendly yet. (This is
an area where targeted government investment would be very effective in
bringing more metadata online).

Ben mentioned that there is some figure that knowledge workers spend XX%
of their time searching for data.
Collecting, and publishing effective metadata will have huge ROI. (Not
sure where to get the figures to back this up)

Collecting good meta data is much harder than it should be, which is why
there is so little metadata around.
The problems are:
1. There is very little automated collection of metadata from current
tools. Eg: If I'm using a map, the extent of the map, the projection,
the resolution, etc should all automatically be populated into metadata
for the user.
2. Metadata when collected is not always collected in a standard format.
Hence the data is not findable by other organisations.
3. Minimal domain specific metadata profiles exist.
Eg: If I'm collection metadata about marine maps, I may want to include
water temperature in a certain field, as well as the map specific data
mentioned above.

* Structure sponsorship similar to the Geoconnections program in Canada.
Geoconnections was a multi million dollar program which tied funding to
globally beneficial goals like the promotion of Open Standards.
Matching funding was provided to government agencies and private
enterprise to achieve these goals.
