Subject: Re: [ubl] Data (Core Component) Harmonization - Some ideas from another community - Review request

Hi Andrew,

I take it it is OK to make a response to the list.

The interesting approach of trying to avoid reinvention of entities, components,
ontologies, etc is that the need changes from one of design to one of research
and deep domain-specific knowledge. As we all know though in UBL TC this
is the ideal everyone seeks but which is not always realised: domain experts are
hard to find when the work has to be mainly, dare I say it, voluntary. If the UK
wishes to emphasise recruitment of domain experts rather than system
designers then that would have to be sustained to a greater extent than we are
currently used to :-)  I tried to word it tactfully but couldn't do
better than that :-)
It would, needless to say, be very expensive (if it wasn't already) to
spend a lot
of time and hard costs on researching what is already implemented or
recruiting experts in what is already implemented. Typically though
the expertise
never seems to go far enough to meet this ideal and some reinvention becomes
more the rule than the exception. Getting a whole host of people together who
actually know in detail what existing systems use for business entities and
components without the need to invent is perhaps just a dream in my experience.
Usually there is a fair bit of guess-work alongside the gap analysis,
even though
that side of things might get downplayed. What therefore worries me about
standardising this is that the embarassing guess-work goes unacknowldged, or
worse, gets covered up and people's expertise exaggerated. A nice ideal though.

Best regards
