Fw: [Aust-NZ] Finding a way forward - GeoNetwork as platform to support ANZLIC Profile of ISO 19115/19139

Tue May 20 17:35:34 PDT 2008

As a long term participant in OGC, I think it is capable of providing A
computational view of a reference architecture.

We may want to support parallel views - for example a registry can easily
support CSW. ebXML, Z39.50, SPARL, OAI etc interfaces from the same content.

This "profiling pattern" is possibly within the OGC purview, but its not
handled well at the moment IMHO because its something that affects
deployers, not technology developers: the need to maintain a consistent
_information architecture_. OGC is a technology vendor association
primarily.

GSDI could own a SDI reference architecture - but doesnt seem geared up for
it.

OSGEO should at least consider the commonality between its projects, out of
business sense. If databases and services and clients and registries dont
handle common metadata, the pieces dont fit together well. Every time I get
asked to advise someone on building tools I have to warn them they have a
huge job gluing the pieces together into a coherent whole, and there will
huge amounts of redundant information scattered across the configurations of
each component that will make it all expensive to build, test and maintain.

Proprietary systems do tend to be better at this, since inter-component
interoperation is often the key to marketing success. Peopele want an
application - and they buy all the components with the expectation the
application will work. IMHO OSGEO could significantly improve its offerings
by having a common information architecture (without necessarily mandating
all projects use it).

2c, but with inflation $64million :-)
