So, If I have a database already established without necessarily a lot

doing that?
If I follow what you're asking for correctly, ...
I'm thinking sort of a step 1, step 2, step 3 type methodology, for example
"well step 1 I like to run this Sparql query here that dumps all
unique RDF structures so I know what I'm dealing with" (note: suspect
it is probably impossible to have such a query but figured I would
give an example)
SELECT distinct ?g
WHERE {
GRAPH ?g {
?s ?p ?o
}
}
will list all the graphs in the store (may take a while).
You could always use the RDF Browser[0] to take this further.
step 2, I use the following tools to automate updating all RDF already
in the database with the new data where applicable
Well, if you store graphs such that their IRI = the URL from which the
resource was gleaned, then a simple stored-procedure looping over the
results of the above query, invoked by the scheduler at regular intervals,
can re-get all the RDF data.
step 3, ah there isn't any.
Correct. Just remember to check your work in iSPARQL or similar :)
