GoodRelations - The Web Vocabulary for E-Commerce

This is the archive of the goodrelations dicussion list

GoodRelations is a standardized vocabulary for product, price, and company data that can (1) be embedded into existing static and dynamic Web pages and that (2) can be processed by other computers. This increases the visibility of your products and services in the latest generation of search engines, recommender systems, and other novel applications.

Enclosed, please find my reply to a bunch of questions related to SPARQL endpoints sent to me as private communication. I thought the answers might me relevant for the readers of this list, too:

> Dear XYZ,
> Thanks for your email. I hope to answer your questions as follows:
> 1. The GoodRelations ontology is just the **schema** for e-commerce data and that is what is available from http://purl.org/goodrelations/v1.owl. Product, company, and offer data published by using the terms in GoodRelations is spread all over the Web. For a list of examples (yet terribly incomplete), see
>    http://wiki.goodrelations-vocabulary.org/Datasets
> Note that ontologies are NOT knowledge-bases, so by definition, they contain no instance data (unless the individuals are part of the schema, like a day of the week). For background information, see

> 2. We do not operate a SPARQL endpoint. There are various public SPARQL endpoints that contain some GoodRelations data, like e.g.
> However, there is currently no "Google-like" RDF repository that offers you free access to the whole Web via a convenient SPARQL endpoint.
> If the repositories from above do not meet the needs for your application, you will have to crawl and cleanse the data yourself, e.g. from
> 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.
