Thanks, great work indeed that will definitively interest the multimedia 
analysis community. I do have some questions:

* From [1], you indicate that the data use the schema 
http://rdf.ontology2.com/vocab# but this URI is not derefencable. Any 
plan to actually publish your vocabulary?

* Looking at the properties you seem to have defined, I wonder why you 
haven't make use of the W3C Ontology for Media Resources [2], in 
particular for describing the renditions of the images. Any reason?

* What is the exact purpose of the namespace 
http://rdf.ookaboo.com/object/ ? Do you have a particular URI scheme for 
identifying the images according to their main topic?

* The multimedia analysis mainly work with the LSCOM ontology [3]. There 
is a light version with only 39 visual concepts and a complete versions 
with hundreds of concepts. People building visual concept detectors 
primarily work with those concepts. Is there any link between this 
ontology and the visual concepts you have selected illustrated by those 
images?

Best regards.
