ADAPT² RDF Bindings.

The main purpose of this wiki is to map entity-relationship models of applications in ADAPT² architecture to RDF.

This wiki has the following structural units:

• ER Models - describe individual adaptive applications. Each entity and relationship is supplied with a list of suggested RDF bindings
• RDF schemata - describe classes and properties with suggested use in describing entities and relationships of applications. Each schema can have several vocabularies identified by prefixes

Conventions

• Objects and Entities are shown in boldface
• Properties and relationships - regular face
• Schema is written in upper case, e.g. DC, vocabulary in lower case, e.g. dc, dcterms
• ER Element is RDF-serialized - ✓ (green check-mark)
• RDF Serialization of ER Element is arguably unnecessary - ✗ (red ballot X)
• Decision on RDF serialization needs clarification - ?¿ (bold blue question mark and inverted question mark)

ER Models

• Knowledge Tree - course portal
• WebEx - application serving dissected examples
• ADAPT² PServices - adaptive functionality profider
• QuizPACK
• CUMULATE - Centralized User Modeling Server

RDF Schemata and Vocabularies

• RDF - has single vocabulary rdf
• RDFS - has single vocabulary rdfs
• Dublin Core - has vocabularies dc, dcterms, dcmitypes
• RSS - has single vocabulary rss (here we mean RSS v.1.0)
• FOAF - has single vocabulary foaf
• OWL

Equivalence

Among various RDF schemata and vocabularies there exist overlap in what they actually mean. For example, dc:title, rdf:label, and rss:title all mean the same. We will maintain (our) classes of equivalence as a reference to RDF homonyms.
