ADAPT² RDF Bindings.
The main purpose of this wiki is to create a process of binding 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 - ?¿ (question mark + inverted question mark)

- Knowledge Tree - course portal
- WebEx - application serving dissected examples
- ADAPT² PServices - adaptive functionality profider
- QuizPACK
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.
