[EP-tech] Re: Antwort: Re: reordering documents

Hi Martin

	This value is also assigned to volatile documents (e.g. thumbnails).  At a guess I would say that when the system regenerates thumbnails, this integer just keeps on going up.  It looks like that function will only be running on the non-volatile documents (which will assign the numbers 1 to n to them).

Recently, we have started getting data where we have more than one PDF: a main one and a number of secondary ones - we can identify which is which easily enough and our importer now handles things correctly. But we have data already in Eprints which has the documents in the "wrong" order and so we want to reorder them.
