ANSWER TO
EXERCISE4.3
The bio sequence attributes can be interpreted as properties as follows:
- element_idThis is the identifier of the bio sequence, so it should be the
URI of the resource. So it corresponds to therdf:IDproperty. - sequence_idThis is another identifier, but it was not declared to be
of typeIDso it is probably a reference to a URI in some other location.

property. - seq_lengthThis is a length so it will be interpreted as a numerical prop-
erty.
