Hi Kingsley:I assume that for now, you don't have a problem with agents crawling your SPARQL endpoint, if need be?While we don't have any problems in principle I would just note that this may not be the most efficient way to get the data and that we would end up paying for all the queries.
Yes! That's my eternal concern about SPARQL endpoints. I know how expensive crawls are, across many dimensions. This is also why at the onset of the LOD project there was an agreed best practice re. publishing SPARQL endpoints and RDF dumps. In a sense, the cost of not having an RDF dump is a SPARQL crawl :-(
I think that this certainly provides us with more impetus to take forward our discussions on making dumps available for each dataset. Am hoping you might be able to hold back awhiles till we can get a decision on that.
Of course, you would have known by now if we crawled your endpoint wholesale. For now, I simply add your endpoint to SPARQL-FED demos, which works fine :-)
