Re: [xml-dev] KML is very extensible ... but why?


I shudder at "...it's just an extraction problem...."

Switching from one ontology to another must just be a mapping problem. ;-)

If those are both "...just..." type problems, why do you think data
scientists keep talking about transformation of data being 80% of what
they do?

Transformation requires an understanding of both the target and source
formats. Or should I say understanding the semantics of both formats?
Sure, if it's well-formed XML, all manner of things are fairly trivial,
if you just knew which ones to do.

In the interest of disclosure, I have seen any number of academic
projects that differ from other projects because they have special need
#1 or #2 or .... To be honest, not really. They typically are encoding
their texts to be different so it works with their tool set (which they
developed), etc. That may not be everyone's experience but it certainly
is mine in the humanities.

I'm not claiming my experience is universal and others may have
different stories to report.

There certainly are other ways to create vendor lock-in, such as writing
your own database software. (Or HR software, I understand the Pentagon
has some 6,000 such systems.)

You may be right, whether encouraged or not, bad behavior (lack of
interoperability) will occur. Still, the lack of same creates a lot of
wasted time and effort.

Enjoy the sunshine, endure the jetlag!
