Hi All,

Apologies, feel like I'm wading in here - but non the less.

issue is how to update / sync rdf; so here's another approach / thought.

timestamp the predicate in a triple.

thus you can query a graph as such:
- <uri> ?p{>date} ?o
- ?s <uri>{>date} ?o
- ?s ?p{>date} <uri>
- ?s ?p{>date} ?o

and obviously you'd have historic data by nature as well.

please do tell me the flaw in my thinking.

many regards,
