Ratings and Poll suggestions

How should we model the various ways of rating posts or other resources?

Example use cases

• favoriting an item
• voting on polls.
• voting on items mechanisms as in digg, or "thumbs up" like in boardgamegeek

• 1-5 stars

Example sites

digg

digg - bury - favorite

ebay

• postive, neutral, negative + comment
• 5 star rating

boardgamegeek

• thumbs up,
• flag potentially offensive item

youtube

• 5 star rating for videos.
• thumbing up and down of comments

flickr

• favorites

del.icio.us

• relations between users and URLs - use sioc:bookmarks ?

deviantart

• rate item with emoticons: joy, sad, love...

wikipedia

• votes expressed in discussion pages - e.g. "agree" "disagree" "neutral" in realtion to a suggestion

Hospitality club

a rdf:Propery;

Ratings

Reuse Danny Ayer's Review vocabulary?

problems:

• max/min ratings mentioned in spec, but missing in RDF/XML
• property reviewer has range foaf:Person

Example usage:

    <review:hasReview>
         <review:Review>
             <review:rating>9</review:rating>
             <dc:description>Blinding</dc:description>
             <review:reviewer>
                 <foaf:Person>
                     <foaf:name>Leigh Dodds</foaf:name>
                 </foaf:Person>
         </review:Review>
     </review:hasReview>
