This is interesting because it shows the different interfaces to the underlying Fedora set of objects.

I'm not saying content models are the same as data models but they are related in that you have to understand your data. What makes for a good model is that it help you make sense of your data and how it can be used. The above mode came from Howard Sachs and came from his slides (PDF) that he gave Open Publish a 2008 conference in Austrailia

I was just looking at this again and I think it makes sense to think of theses as being the types of metadata (along with technical) that describe a digital object.

In the absence of knowledge

Roy Fielding was talking about specialization. He was talking about when and how he needs to talk as a specialist and who should and can understand this. He then posts a long quote from James Burke and how he described the problem of specialization.

Then, in the absence of knowledge, what is there to appeal to except our emotions? And then the issue becomes "national prestige," or "good for jobs," or "defense of our way of life," or something. And suddenly you're not voting for the real issue at all.

When we talk about technology here, it is most often with out knowledge so that what really happens is there is some appeal to emotions and the real issues are never addressed.

He ends with this sentence which is pretty killer

We are communicating really, really fast these days. Don't pretend that you can keep up with this field while waiting for others to explain it to you.
The Value of using XML

from Kurt Cagle

XML's primary benefit comes about not because of its performance (which even most XML gurus will cringe at) but because it provides a standardized mechanism for abstraction. If I encode a pipeline process in XML, then it doesn't really matter (for the most part) whether I work in C++, .NET, PHP, Java, JavaScript, Perl, Python, Ruby, Haskell or Miranda. With the XML representation, I can describe processes that can work in any of the languages given, and more importantly, with those processors and some form of web services pipe I can even pass pieces of processes to different languages, machines, or environments and still get my tasks accomplished.
