In my opinion, there should not exist any placeholder for Foreign Keys. If a FK is mandatory, you need to publish it. If not, just make them optional. If you put a placeholder in a FK, then the word mandatory has no real meaning. On Mon, Oct 26, 2009 at 1:12 PM, <stephen.burke@stfc.ac.uk> wrote:

While I'm at it, another thing that came up recently was that we don't seem to have a placeholder for unique IDs, e.g. a mandatory foreign key. Do you have any suggestions? (So far I went for "$UNDEFINED$" in the absence of inspiration ...)
