The biggest problem I've seen above is that XML documents are just being
made up without any schemas or relationships to other documents.  The
best thing about XML is the namespaces, because you can write <clothing:tie=
/>
and <rope:tie/> and know that the two are different contexts.  (Even
though nobody seems to do that, which is a real shame.)

Unfortunately, there's no way to tell what way two different namespaces
are related to each other, and this is where RDF comes in.

RDF has an XML serialization format, but you can store RDF in any format
you want.  RDF's strength is its focus on relationships, and what you
can infer from the ones given.  Here's some RDF in subject, predicate,
object triples:

<urn:person:Sandra> -> name    -> Sandra
<urn:person:Sandra> -> gender  -> female
<urn:person:Sandra> -> sibling -> <urn:person:Kevin>
<urn:person:Kevin>  -> name    -> Kevin
<urn:person:Kevin>  -> gender  -> male
<urn:person:Kevin>  -> parent  -> <urn:person:Sarah>
<urn:person:Sarah>  -> name    -> Sarah
<urn:person:Sarah>  -> gender  -> female

With this data, you can easily infer that:

Sandra has a brother.
Sandra's mother's name is Sarah.
Sarah has at least two children.

And since everything can be given a namespace that maps back to the
basic RDF types, you can easily pass this information in and out of
other systems, and everybody will know what you are talking about.

Specifically, serializing Ruby objects in XML is a waste if only Ruby
can understand the generated XML.  Nobody else can understand the
relationships and easily use them into other systems.  Using RDF, the
relationships are easily parseable for use in other systems, making
them interoperable without pain. =20

Yes, I agree everything I've done with REXML has been straightforward
and simple.  I'm just pointing out that throwing XML into the midst of
things isn't going to necessarily give you any direct gains without a
bit of thought.
