Here is 90% of what you are look for:

  Redland RDF Application Framework

You can read the details of the Redland blurb on the site but
addressing your particular requirements, it does everything on your
list in a single library except for:

  URI/network handling - easy to use something like libcurl, libwwww
    that does that in <10 functions.  I plan to add an interface to these.

  Serializing - I have working code for this now.

  Querying - I assume you mean a query language.  In the design stage
    at present.

Being more positive, I guess I can take your requirements as feedback
that these, already planned, features are still needed.

I would say it is not that bad ;)
