Ontology and vocabulary

The XYZ ontology extends the Schema.org and DBPedia ontologies.

Schema.org

Schema.org provides a collection of schemas, i.e., html tags, that webmasters can use to markup their pages in ways recognized by major search providers. Search engines including Bing, Google, Yahoo! and Yandex rely on this markup to improve the display of search results, making it easier for people to find the right web pages.

We use a part of the Schema.org ontology to defines the objects returns in the XYZ API.

Depending on the requirements we will complete patterns with other types of ontologies but trying to keep up standards and simplicity.

• Thing – The most generic type of item
• Event – An event happening at a certain time and location
• GeoCoordinates – The geographic coordinates of a place or event
• Offer – An offer to transfer some rights to an item or to provide a product or service
• PostalAddress – The mailing address
• Place – Entities that have a somewhat fixed, physical extension.

Dublin Core Metadatas

In all the datas objects use 3 specific properties from the Dublin Core Metadata schema :

• created
• modified
• publisher

Note : The Dublin Core Schema is a small set of vocabulary terms that can be used to describe web resources (video, images, web pages, etc.), as well as physical resources such as books or CDs, and objects like artworks. The full set of Dublin Core metadata terms can be found on the Dublin Core Metadata Initiative (DCMI) website.
