The RDF dump takes many days to assemble, so the actual data capture date for different categories may be spread across nearly a week.

Once the data capture has completed, it takes another day or two to error check that data and build the RDF file, and then publish it.

I can't remember what happened that far back, but there have been a few occasions when the process has got stuck at the publish stage for example.

On those occasions, the system may have needed a nudge to get things finished.

Once the RDF is published it might not be picked up by users such as Google for a while, and once they have picked it up, they usually take 10 to 14 days to process it and get the data online on their site.
