Overview

The GoodRelations Vocabulary • A universal and free Web vocabulary for adding product and offering data to your Web pages. • Compatible with all relevant W3C standards and recommendations – RDF – OWL http://purl.org/goodrelations/ 8

GoodRelations: One Single Schema for A Consolidated View on E-Commerce Data Extraction Arbitrary Query and Reuse Manufacturers Retailers Payment Delivery Product Model Warranty Master Data Shop Spare Parts & Offerings Auctions Consumables 9

GoodRelations Design Principles • Keep simple things Lightweight Heavyweight simple and make Web of Data Web of Data complex things possible LOD OWL DL • Cater for LOD and OWL RDF + a little bit DL worlds • Academically sound • Industry-strength engineering • Practically relevant 10

GoodRelations: License • Permanent, royalty-free access for commercial and non-commercial use. http://purl.org/goodrelations/ 11

GoodRelations vs. eClassOWL etc. GoodRelations: Products and Services Companies & Offers Ontologies • BusinessEntity • Industry-specific • Offering ontologies for describing • WarrantyPromise types of products and services • … – eClassOWL – freeClassOWL – CEO - Consumer Electronics Ontology 25.10.2009 12

Domain Structure and Use Cases

Albert Einstein on Ontology Engineering "Make everything as simple as possible, but not simpler.“ Albert Einstein 14

Basic Structure of Offers: Agent-Promise-Object Principle Object or Agent 1 Promise Happening Compensation Transfer of Rights Agent 2 15

The Minimal Scenario • Scope – Business entity – Points-of-sale – Opening hours – Payment options • Suitable for – Every business – E-commerce and brick-and-mortar 16

The Simple Scenario • Scope: Minimal scenario plus – Range of products or services – Business functions – Eligible regions or customer types – Delivery options • Suitable for – Any business: E-Commerce and brick-and-mortar – Specific products or services 17

The Comprehensive Scenario • Scope: Simple scenario plus – Individual products or services – Product features – Pricing, rebates, etc. – Availability • Suitable for – Any business: E-commerce and brick-and-mortar – Specific products or services – Structured product database 18

Product Model Data Scenario • Scope – Individual product models – Quantitative and qualitative features • Suitable for – Manufacturers of commodities 19

Products vs. Product Models Product Model: Products: What you buy, “Datasheet” possess, and use • Intangible object • (Mostly) tangible object • “Ferdinand Porsche that can be owned and created the VW Beetle” used. • Not a subclass of • My VW Beetle has a products! mileage of 42,000 • Its serial number is 123456789 25.10.2009 20

Product Models vs. Products • Product models define the defaults for a subset of a products features ex:FordTModel ex:hasWeight “400”. implies that likely (!) ex:MyFordT ex:hasWeight “400”. Important: Only products are offered for sale etc 25.10.2009 21

Products: Actual vs. Anonymous Individuals • Sometimes you offer a particular object – myMacBookPro • Sometimes you offer products from a set of anonymous instances – A retailer does not expose every single book copy on stock over the Web – Those are only quantified existentially. 25.10.2009 22

Products: Actual vs. Anonymous Individuals • Sometimes you offer a particular object – Example: eBay auction – gr:ActualProductOrServiceInstance • Sometimes you offer products from a set of anonymous instances – Example: New books on Amazon – gr:ProductOrServicesSomeInstancesPlaceholder 25.10.2009 23
