-
-  A simple composite data source implementation. A composit data
-  source is just a strategy for combining individual data sources into
-  a collective graph.
-
-
-  1) A composite data source holds a sequence of data sources. The set
-     of data sources can be specified during creation of the
-     database. Data sources can also be added/deleted from a database
-     later.
-
-  2) The aggregation mechanism is based on simple super-positioning of
-     the graphs from the datasources. If there is a conflict (i.e., 
-     data source A has a true arc from foo to bar while data source B
-     has a false arc from foo to bar), the data source that it earlier
-     in the sequence wins.
-
-     The implementation below doesn't really do this and needs to be
-     fixed.

-
-  A simple cursor that enumerates the elements of an RDF container
-  (RDF:Bag, RDF:Seq, or RDF:Alt).
-
-  Caveats
-  -------
-
-  1. This uses an implementation-specific detail to determine the
-     index of the last element in the container; specifically, the RDF
-     utilities maintain a counter attribute on the container that
-     holds the numeric value of the next value that is to be
-     assigned. So, this cursor will bust if you use it with a bag that
-     hasn't been created using the RDF utility routines.
-
-  2. This is sort of a continuation of (1), but -- it's not smart
-     enough to notice duplicates.
-
-  TODO. This is way too brain dead to handle aggregated RDF
-  databases. It needs to be upgraded in a big way.

-  TO DO
-  -----
-
-  1) Figure out a better way to do "pluggable resources." Currently,
-     we have two _major_ hacks:
-
-       RegisterBuiltInNamedDataSources()
-       RegisterBuiltInResourceFactories()
-
-     These introduce dependencies on the datasource directory. You'd
-     like to have this stuff discovered dynamically at startup or
-     something. Maybe from the registry.
-
-  2) Implement the CreateDataBase() methods.
