Section 2.2

{subject, predicate, object}
should be:
(subject, predicate, object)

since, in common mathematical usage, {a, b, c} denotes three entities
whose order does NOT matter, whereas (a, b, c) denotes three entities
whose order DOES matter.

Figure 3-5

Throughout the book, blank nodes are drawn as rectangles, but
they should be drawn as ovals, according to the text. For instance, p20 says "blank
nodes are shown as an empty circle". p38 says "an oval with a generated identifier
is drawn". But in the figures, they show rectangles, not circles/ovals.

The URI indicated in the figure is http://burningbird.net/articles/monsters3.com
rather than http://burningbird.net/articles/monsters3.htm as it should be.

Figure 3-1

"monsters3.com" appears where "monsters3.htm" should occur in the URI of Figure 3-1.
This mistake occurs again in Figure 3-2, Figure 3-3, Figure 3-4, and Figure 3-5.
The correct URI is listed in the RDF code snippets.
