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.

[goodrelations] New additionalType property in schema.org

Dear all:

I am happy to announce that the sponsors of schema.org, i.e. Google, Yahoo, Bing, and Yandex, have just implemented my proposal (from September 2011) to add a new property additionalType to http://schema.org/Thing and thus also to http://schema.org/Product.

This allows using the more than 300,000 precise product type identifiers from our http://www.productontology.org service for telling search engines very, very precise the type of products or services you are selling.

For example, a racing bike should now be marked up as follows:

<div itemscope itemtype="http://schema.org/Product">
    <link itemprop="additionalType" href="http://www.productontology.org/id/Racing_bicycle" />
    <!-- other schema.org properties go in here -->

You can use any reasonable Wikipedia entry for that.



for more details.

This is also the first step in the ongoing effort to make the GoodRelations vocabulary fully available from the schema.org namespace.

Best wishes
