well I'd say it's encoding a false assertion, it says

the OM symbol transc1#sin is owl sameas an OM symbol  transc1#sin that 
has been annotated wth the mathml3 definitionurl attribute, pointing at 
dlmf. So it's legal OpenMath but I don't think it means what you want to 

Firstly as I said before if you want to make an owl assertion I;d do it 
in owl, using something equivalent to
for the openmath (and an rdf rendition of dmlf for the other side, and 
then just use owl syntax.

However if you wanted to make the assrtion in openmath you want to say 
OM sin is same as dmlf sin so something like

       <OMS cd="owl" name="sameAs"/>
       <OMS cd="transc1" name="sin"/>
       <OMS cd="dmlf" name="sin"/>

and separately you want to state that the canonical uri for dmlf sin is 
whatever it is, which could be something like

       <OMS cd="omrdf" name="URI"/>
       <OMS cd="dmlf" name="sin"/>
       <OMSTR>http://.... whatever</OMSTR<
