Try to guess if an node string is a blank node identifier.

<p>
The guessing is done by assuming the object is a blank node if it matches
^_: like N-Triples, N3 and related.

<p>
Try to guess if an object string is a literal or a resource.
</p>
<p>
The guessing is done by assuming the object is a URL if it matches
  ^[<code class="function">isalnum()</code>]+:[^<code class="function">isblank()</code>]+$
</p>
<p>
This will be fooled by literals of form 'thing:non-blank-thing' but
is good enough.
