Hi Bruce and John,
If you're asking just simply about the differences between the
Australian profile and ISO19115/19139 then I'm sure John Hockaday and no
doubt others have presentations that will give all the details (I think
John's presentation to the metadata open forum in Sydney would be a good
place to look).
If the question is wondering why a profile which isn't vastly different
to ISO19139/19115 took a while to implement in GeoNetwork then maybe you
need to think about some of the surrounding issues. First and foremost,
there is the question of schema parsing in GeoNetwork to build an
editable representation of any 19139/19119 based metadata record - this
was working in the BlueNet MEST 1.0 release in October/November 2007
(after the OSDM sponsored GeoNetwork workshop) and in trunk 2.1 - but
some of the more arcane stuff wasn't sorted out until Dec 07 (it was
incorporated in the trunk for the 2.2 RC0 release in the first week of
Jan 08).
At the same time, there was the problem of a general method of
supporting more than one profile of ISO19139 (a variation on existing
support for different metadata standards) in GeoNetwork and the extra
problems of adding support to GeoNetwork to find and use the ancillaries
associated with the different profiles, including:
- schematrons for content checking: CSIRO developed them for ANZLIC, we
included them in the validation report and added support for error flags
in the editor
- xslts to convert to/from the new profiles: developing (we developed
one for the Marine Community Profile, and there was the ANZLIC supplied
on), testing and including in the tools
- menus to support profile groupings of elements eg. ANZLIC Minimum,
ANZLIC Core for data sets etc
and probably others that I've (happily!) forgotten.
Ideas for implementing profiles were also not very accessible - we
followed discussions on SEEGRID and used the WMO profile as an
additional example - and it follows that there were very few (if any)
accessible metadata tools that handled profiles and ancillary info at
that time.
Of course, like most things, this will be looked upon as 'straight
forward' with the benefit of hindsight and as it moves into the main
stream :-).
Hopefully this might provide some of the answers to your question
(assuming I've understood it correctly)!
Cheers,
Simon
