Hasan reopened CLEREZZA-38:
---------------------------


In representations.rdf
- In Property isIconFor
-- isIconFor is a DatatypeProperty, not an ObjectProperty, as it is defined now
-- property rdfs:isDefinedBy is incorrect
-- suggest to rephrase the definition to: "Points to a string specifying the resource type for which the subject is an icon."

In ThumbnailService
- unused imports
- cannot import org.apache.clerezza.rdf.ontologies.EXIF
  (org.apache.clerezza.rdf.ontologies/0.11-incubating-SNAPSHOT/org.apache.clerezza.rdf.ontologies-0.11-incubating-20091223.111515-4.jar does not contain EXIF)
- In public getThumbnailUri
-- missing java doc for param width and height

- In private getThumbnailUri
-- it is assumed that the store always has EXIF.width and height properties for each thumbnail 
   subject. I think bad things can happen and the store might not have these properties for a 
   thumbnail, so getObjects(EXIF.width).next() might throw an exception.
   -> Suggest to avoid this exception by using hasNext() and handle the missing EXIF.width prop 
   accordingly for example ignore and continue the loop.

In AlternativeRepresentationGenerator
- getService may return null, therefore contentHandler.put can throw NullPointerException.
  (probably this is ok, since the method may throw RuntimeException and 
  node.addProperty happens after contentHandler.put)
- don't understand the purpose of the condition lastIndexOfDot >= (oldUri.length() - 6)
  in createThumbnailUri.
  a short inline comments might help

In pom.xml of ...core

	<description>Provides a Meta Data Generator that generates alternative
		representations for data of	various meta types</description>
	<dependencies>

- typo "meta types"?
- would change "various" to image/* as mentioned in AlternativeRepresentationGenerator
- would add that this bundle also provides a JAX-RS service to retrieve a thumbnail of an 
  InfoDiscoBit via http redirection
