Having a bf:Note class makes sense to me. The current approach seems exhaustive enough to be cumbersome, but probably not exhaustive enough to capture the full range of possibilities in the source data. Not all notes come from 5XX fields. Here is a sample marc2bibframe conversion of a record for a serial: MARC: http://bibframe.org/resources/Jqc1410365115/marcxml.xml BF: http://bibframe.org/resources/Jqc1410365115/bibframe.rdf Here, bf:frequencyNote maps to the 310 field (Current Publication Frequency). Unfortunately, it also maps to the 321 field (Former Publication Frequency). This would seem to be a not insignificant loss of information. 5XX fields that are distinct in MARC are mapped to generic bf:note properties (515, 588). bf:frequency doesn't appear, but maybe it was meant to correspond to the 008 fix field for continuing resources, which also has a value for frequency (position 18). The need for two distinct properties remains unclear. In short, a bf:Note class with bf:noteType values might provide greater flexibility and preserve more of the original semantics. Tim -- Tim A.
