Dear Cristian,
Thanks so much for this, we have featured your dataset on our homepage:
http://linkeddatafragments.org/data/
What is LDF?
Please allow me to make a technical correction here:
Linked Data Fragments are a uniform view
on _all_ possible interfaces to Linked Data,
not just the light-weight interface that Cristian set up:
- SPARQL endpoints offer Linked Data Fragments;
you can select a part of a dataset corresponding to a specific SPARQL query
- a server of Linked Data documents offers Linked Data Fragments;
you can select a part of a dataset corresponding to a specific subject
- …
What all those interfaces have in common,
is that they offer some part, some fragment, of a dataset;
hence the name “Linked Data Fragments”.
In addition, we have introduced a new kind of interface:
Triple Pattern Fragments, which offer access to parts of a dataset by triple pattern.
This is indeed a very lightweight system for the server,
as you can host live data without much processing resources.
SPARQL queries can be executed on the client side,
as Cristian's client instance shows:
http://client.wikidataldf.com/
«a publishing method [for RDF datasets] that
allows efficient offloading of query execution from servers to clients
through a lightweight partitioning strategy. It enables servers to
maintain availability rates as high as any regular HTTP server,
allowing querying to scale reliably to much larger numbers of
clients»[1].
So the above definition is about triple pattern fragments,
not Linked Data Fragments interfaces (which include SPARQL endpoints) in general.
Thanks, Cristian, for setting this up!
I hope the Wikidata community finds good use for it.
Finally, live data from Wikidata can be queried with SPARQL :-)
Best,
Ruben
