• Who sells solar panels with at least 12 A output?
• Who can repair my Sony TV set? • Who sells Volkswagen cars? • etc.

Core Semantic Web Technology Pillars • URIs for everything • RDF: A data model for exchanging conceptual graphs
based on triples – Triple: (Subject, Predicate, Object) – Exchange Syntax: RDF/XML, N3, etc.
• RDFS and OWL: Formal languages for specifying the exact meaning of vocabularies – foo:human rdfs:subClassOf foo:mammal
• SPARQL: Standardized query language and endpoint interface for RDF data

Required Vocabularies for E-Commerce • An vocabulary for product
types and features – by function, usage, or nature
• An vocabulary for offer specifications
• An offer is basically a relation between – an agent, – a set of objects, – a set of property rights, – an audience, and – a set of terms and conditions.

Why Should I Bother? • Web Shops: Better visibility in latest generation
of search engines (e.g. Yahoo) – Same holds for any business that has a Web page,
from A as in Amusement Park to Z as in Zoo. • Manufacturers: Allow your retailers to reuse
product feature data with minimal overhead at both ends.
• Software Developers: Help your customers to use and generate Semantic Web data. It’s easy!

What Should I Do? • Web Shops: Create a GoodRelations data dump of
your range of offers (rather simple) • Vendors of Web Shop Software: Create
GoodRelations import and export interfaces (we can help you with that)
• Every Business: Ask your webmaster to create at least a basic description of your range of products or services
• Entrepreneurs: Invent new business models based on GoodRelations data

Step-by-Step (1) • Data Sources
– Form-based data entry – RDBMS – XML, e.g. BMEcat – CSV – Google CSV, RSS 1.0,
RSS 2.0
• Amount of Detail and Data Model – What shall be included? – How shall the type of
products be represented?
29.04.2009 24
• Data Delivery Options – RDFa: Embedding Meta-
data in XHTML – RDF/XML: Extra File – dataRSS: Yahoo Feed
Format

Step-by-Step (2) • Update Mechanism & Data Management
– PHP on demand – Script-based data dump
• Publishing the Data – Server Configuration – Notifying Semantic Web Crawlers, Yahoo, – Semantic Sitemaps
• Applications
