In terms of metadata for archival photographs, there are a few ways to handle this, e.g., a Dublin
Core Qualified approach. Coverage is often used to establish the time period of an item; the date
then reflects the date it was uploaded or added. You could also use (if applicable)
DateCopyrighted or DateSubmitted from Dublin Core. From an archival standpoint, using the
date of the object photographed is confusing but limits search capabilities, too -- just for the
reasons that have been pointed out (undergraduates have asked for photographs of dinosaurs...)
Although photographs of paintings seem to be one area that is an exception because the
photograph is (sometimes) seen as the surrogate for the painting. I do think Coverage or time
span or era is extremely useful for archival photographs.
In terms of traditional bibliographic cataloging (libraries), they would use the 260 MARC field
(publisher, place, copyright date field in a library record) but then would use another field (and
notes, most likely) to add in information about the original book or item. More recent practices
(RDA, the new standard) would use multiple 264 MARC fields (a new field), meant to separate out
the publisher, distributor, manufacturer, and copyright date. So, each 264 could have different
dates with copyright being clearly identified by field labels. If you search in a library catalog right
now, you may or may not be able to see those, as this is really just about a year out in terms of
implementation (which means lots of old records). Temporal / coverage date would be included in
the subject headings aka the controlled vocabulary keywords. So, you might see something like
the example below. Anyhow, my point being is that the publication date (similar to the upload
date, if you think about everything on the internet as being "published") is analogous. The original
date would be separated out, depending upon the type of item - facsimiles (surrogates like the
painting example above) are handled a bit different, as the original date is the date of publication,
but the differences in dates are accounted for elsewhere within a record.
I don't know if that helps or not - but dates are extremely important and libraries have traditionally
had many ways of reflecting the different types of dates (not that the records are always correct --
it is complex and the standards have evolved over the hundreds of years of library metadata work
(because card catalogs and journals are just a print form of metadata). :-)
