Re: [xml-dev] Why does XML call them "attributes" and not name-value pairs?

Argh, next we'll be arguing about data vs metadata.  I concluded decades ago that the distinction is at best not useful but probably not even real.

OK, let me try to put it in another way. I think that an attribute contains a "fact", or a "statement" about a particular object.

An attribute's value is not a structured object (although it can contain the serialization of an object as a flat string), and it is meaningless for an attribute to have two separate instances (because they will be stating the same fact or property twice).

So, an attribute is not a structured object but is always a property of an object, which property is not itself an object.

Thanks,
Dimitre

I'm afraid so. Philosophers have devoted their lives to these questions, and even in the more mundane world of data modelling, many books have been written.

Since you've chosen the human body as your subject area, consider disease. Is a disease a thing, or an attribute of a thing? Is there an absolute answer to this question, or is it an engineering choice in how we model it?

Perhaps every attribute is a relationship of one thing to another. Hence RDF triples.
