Archive Content

This archive contains RDF descriptions from DBpedia Live. It is the result of remaining in sync with DBpedia Live's dumps and changesets and covers:

All versions of RDF descriptions from the DBpedia Live dataset since December 2011.

Note that this archive is experimental and has mainly been set up to perform tests in the context of the ResourceSync project.

Memento Protocol Information

The archive is accessible via the Memento "Time Travel for the Web" protocol. Hence, it supports datetime negotiation to access a version of an RDF description as it existed at a specific moment in time. Check out the brief introduction to Memento if you are not familiar with it.

Presuming the Original Resource (current version) is http://dbpedia.org/data/Oaxaca, then the resources that are relevant for the Memento protocol are:

TimeGate: http://megalodon.lanl.gov/dbpedia/timegate/http://megalodon.lanl.gov/dbpedia/data/Oaxaca
Memento: http://megalodon.lanl.gov/dbpedia/memento/000000000335736 ; http://megalodon.lanl.gov/dbpedia/memento/000000015516055 ; etc.
TimeMap: http://megalodon.lanl.gov//dbpedia/timemap/link/http://megalodon.lanl.gov/dbpedia/data/Oaxaca
TimeBundle: http://megalodon.lanl.gov//dbpedia/timebundle/http://megalodon.lanl.gov/dbpedia/data/Oaxaca

Further information:

The above pattern only applies to .../data/... URIs, not to .../page/... or .../resource/... URIs.
The TimeBundle is a more expressive, RDF-based, version of the TimeMap. One major distinction is that the TimeBundle expresses the interval of temporal validity of a Memento, i.e. the time period in which the Memento was the current version of the Original Resource.
Formats that are available via content negotiation from the archive are: RDF/XML ; n3 ; nt ; turtle ; HTML

Integration with the Original Dataset

The original dataset is really WikiPedia. The process by which RDF data is continuously extracted from WikiPedia is described on the DBpedia Live page. However, there is no system that makes the resulting Live DBpedia RDF descriptions, e.g. for Oaxaca accessible via a URI. Hence, there is no original RDF dataset with which this archive can be integrated. Eventually, integration of this archive with the regular DBpedia could be considered.
