Dear Pantelis,

I have similar issue with RDFs generated by ambit, we are trying to
figure out the reason. 

http://ambit.uni-plovdiv.bg:8080/ambit2/dataset/1?max=1

    * Untyped Object Property: http://www.opentox.org/api/1.1#dataEntry
    * Untyped Object Property: http://www.opentox.org/api/1.1#compound
    * Untyped Object Property: http://www.opentox.org/api/1.1#feature
    * Untyped Object Property: http://www.opentox.org/api/1.1#values
    * Untyped Data Property: http://purl.org/dc/elements/1.1/type
    * Untyped Data Property: http://purl.org/dc/elements/1.1/identifier
    * Untyped Data Property: http://purl.org/dc/elements/1.1/title
    * Untyped Data Property: http://purl.org/dc/elements/1.1/description
    * Untyped Data Property: http://www.opentox.org/api/1.1#value


Best regards,
