It looks like Wikidata has started to collect SPARQL endpoints. Here’s the current list:

Hi
What is the relationship between this effort and the lod cloud diagram?

Hi Alasdair,

Ultimately, this effort should make the bubbles in the LODCloud easier to understand e.g., does a node indicate existing of a SPARQL endpoint or just a published dataset.

In the current state, the LODCloud is a little unclear to many. As an insider, I know that the LOD Cloud comprises the following:

1. Datasets published using Linked Data principles

2. SPARQL endpoints associated with Datasets -- that may or may not be functional which opens up a can of worms that are typically quite negative

One issue that has lingered in the wells of confusion for years is the fact that SPARQL actually provides an effective tool for Linked Data Deployment, as exemplified by DBpedia. It scales better than trying to handle the name -> address indirection manually using a Web Server. A few years ago that claim would have been challenged by a lot of doubt, but 10+ years later we have concrete proof :)

Hi,
 So, Bio2RDF's datasets are now just served from one sparql endpoint, and are loaded into different (versioned) graphs. how do you want to deal with this?

Hi Michel,

Is there now a canonical endpoint that renders all the others redundant? Anyway, just add the endpoint in question or indicate the ones to be dropped.

Hi Everyone,

As part of the LODCloud effort (starting in 2007), a number of SPARQL Endpoints emerged around the initial SPARQL endpoint provided by DBpedia. Today, that cloud has grown into the largest Knowledge Graph on earth (by far!) and continues to drive new frontiers related to Artificial Intelligence and Machine Learning.

Having established itself as the preeminent global Knowledge Graph on earth, it is extremely important that we maintain an active list of SPARQL endpoints using practices that scale. Thus, we are providing a shared Google Spreadsheet for crowd-sourcing the maintenance of SPARQL endpoints that make up this important Knowledge Graph.

Please contribute your SPARQL endpoint(s) to the spreadsheet.
