Public endpoints

= Public Endpoints =

There is currently no "Google-like" RDF repository that offers you free access to the whole Web via a convenient SPARQL endpoint.

Some public SPARQL endpoints offer a moderate amount of such data, e.g.
 * http://sparql.sindice.com/
 * http://uriburner.com/sparql
 * http://lod.openlinksw.com/sparql
 * http://linkedopencommerce.com/sparql

If this does not meet the needs for your application, you will have to crawl and cleanse the data yourself, e.g. from
 * http://wiki.goodrelations-vocabulary.org/Datasets

Limitations
Note that crawling crawling, cleansing, and consolidating structured data at Web scale is a non-trivial task, so do not expect someone else to do it for you for free. It may be a good business idea to offer such a service.

None of the currently known free and public SPARQL endpoints provide a sufficient coverage and currency of e-commerce data to power serious e-commerce applications.

You will have to do that on your own if your business idea requires that.

Setting up your own SPARQL endpoint
