</SPAN>I think the idea with this distinction is that there may be multiple
items that disseminate different assertions (but in the same metadataFormat)
about the same resource. <SPAN class=287222517-17032005><FONT

<DIV dir=ltr align=left><FONT size=2><SPAN class=287222517-17032005><FONT

Cindy's items says the dc:title is "The homepage of the W3C".<BR><SPAN

<DIV dir=ltr align=left><FONT size=2><SPAN class=287222517-17032005><FONT
face=Arial color=#0000ff>that makes sense, of course. thanks. is there
anyone 'using' the distinction in that sense? since we're at it, how common is
it for datestamps to be actually attached to records, as per specs?
iow, who's keeping persistent records in different formats and allow the latter
to change independently from items and each other? Aggregators? What class
of changes are record- but not item-dependent, btw?
