#if there is only one metaDataProperty you can just do:
#ds.metaDataProperty=csml.parser.csString('Data (c) 2007 CCLRC // www.cclrc.ac.uk')

#but if there are several you need to put them in a list:
mdplist=[]

####### Generating XML #################
            
#call the toXML method of the Dataset object:
csmldoc = ds.toXML()
#parse and pretty print the result
strCSML=csml.parser_extra.PrettyPrint(csmldoc)
strCSML=csml.parser_extra.removeInlineNS(strCSML)
print strCSML

#(you could save strCSML to a file at this point)
