008/35-37 and 041 $a/$d conversion #38

Open wafschneider opened 7 years ago

Currently, a bf:language property of the work is generated both by the 008/35-37 and by 041 $a and $d. Of the 041, the MARC standard states:

Used in conjunction with 008/35-37 (Language). If there is a code in 008/35-37, it is recorded as the first code in subfields $a or $d (for sound recordings) of field 041.

Should the conversion for the 008/35-37 take the 041 into account, to avoid duplicate bf:language assertions? If both 008/35-37 and 041 $a/$d are present, which would be preferred?

+1 for avoiding duplicate assertions. However, depending on the amount of indirection involved, this could happen naturally - if the assertions was simply e.g. <work> bf:mainLanguage "eng" (see my proposal in #37) then several assertions like this in the RDF/XML output would collapse into a single triple when interpreted as RDF.

If the languages in 008 and 041 are different, I think just including them all in the output would make sense.
