Hello!

I have some questions concerning GeoNames RDF dump.

1. How often is it updated?

2. Is there any way to customize it? I need just cities1000 and countries datasets. One way is to load the whole RDF dump and use only things I need... but 100 millions of triples scaled by users number will kill my current deployment. The other way is to load cities1000+countries to relational database but it will disable some of our RDF specific usecases.

Regards,
Alexander

The rdf dump is updated infrequently and there are no customizations.
You know how resource hungry it is.
The csv dump is generated daily.

Marc,

First I tried try to use cvs dump through some rdbs2rdf tool but finally decided to create customizable GeoNames Relational2RDF converter.

P. S. What if make users pay for full GeoNames RDF dataset generation? There should some page displaying the generation date and if the user thinks he needs more up-to-date RDF dataset he pays some money, then Amazon EC2 (or any other cloud hosting) instance is launched and RDF dataset is generated and after that instance is terminated (and RDF dataset becomes available to everybody). Let's roughly estimate it as one day of "Extran large instance" work. 0.68 * 24 = 16.32$ (of if your software is Windows specific - 23.04$). I think this is not so much money for those who need up-to-date geodata (furthemore several people may come together).

You are absolutely right. If users pay for it then it is possible to
generate it much more frequently. It could be an additional option for a
'premium dump' scenario.
