Thanks for your interest in this discussion! I have edited the description
of the proposed Periodical "issn" property at
http://www.w3.org/community/schemabibex/wiki/Periodical#Thing_.3E_CreativeWork_.3E_Collection_.3E_Periodicalto
reflect the repeatability of the property if one wishes to reflect
different editions, with an example of format as the most likely reason for
adding multiple "issn" properties..

If the ISSN-L is currently rarely displayed, then perhaps we should simply
be silent about it in the current Periodical proposal rather than minting a
separate "issn-l" property at this time. That said, I don't think there
would be significant harm caused if someone did end up using the "issn"
property to identify an ISSN-L, given that it would be likely to be one of
several "issn" properties in that case.

If you have further comments about the current proposal and want to talk
with us further, we certainly welcome your participation on the list and on
the conference calls! I believe our next call was to be rescheduled for
next Wednesday, but don't have the scheduling information ready at hand
(and the minutes from our last meeting haven't magically been populated at
http://www.w3.org/community/schemabibex/wiki/Meet_20131121 yet - heh).

Thanks,
Dan
