All,
Quick FYI.
What is Virtuoso+DBpedia AMI for EC2?
An pre-installed and fully tuned edition of Virtuoso that includes a
fully configured DBpedia instance on Amazon's EC2 Cloud platform.
Nice work :)
Benefits?
Generally, it provides a no hassles mechanism for instantiating
personal, organization, or service specific instances of DBpedia within
approximately 1.5 hours as opposed to a lengthy rebuild from RDF source
data that takes between 8 - 22 hours depending on machine hardware
configuration and host operating system resources.
From a Web Entrepreneur perspective it offers all of the generic
benefits of a Virtuoso AMI on EC2 plus the following:
1. Instant bootstrap of a dense Lookup Hub for Linked Data Web oriented
solutions
2. No exposure to any of the complexities and nuances associated with
deployment of de-referencable URIs (you have a local DBpedia replica)
Does this mean all the URIs are dbpedia.mysite.example.com rather than
dbpedia.org/* ?
In http://kingsley.idehen.name/page/Linked_Data I see
'http://dbpedia.org/resource/Linked_Data' at the top of the page, but no
owl:sameAs to http://kingsley.idehen.name/page/Linked_Data
The raw data links aren't working for me at the moment:
eg.
curl
"http://kingsley.idehen.name/sparql?default-graph-uri=http%3A%2F%2Fdbpedia.org&query=DESCRIBE+%3Chttp://kingsley.idehen.name/resource/Linked_Data%3E&output=xml";
<?xml version="1.0" encoding="utf-8" ?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#";
xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#";>
etc., ... but I get the impression the RDF files use the main dbpedia
URI space, while the HTML uses local references. If that's the case, how
might this look in RDFa?
cheers,
Dan
3. Predictable performance and scalability due localization of query
processing (you aren't sharing the public DBpedia server with the rest
of the world)
Features:
1. DBpedia public instance functionality replica (re. RDF and (X)HTML
resource description representations & SPARQL endpoint)
2. Local URI de-referencing (so no contention with public endpoint) and
part of the Linked Data Deployment
3. Fully tuned Virtuoso instance for DBpedia data set hosting
