<p>AFAIK (maybe my colleagues will chime in and correct m,e if I am
wrong), there is no official IUCr data item for the "Article ID".
Publishers are not decided either – some (re)use first-page as the
article ID (RSC), some ditch page numbers altogether and add the
article identifier, sometimes without even specifying what
properties it has (e.g. will it change for the new revisions of
the paper).</p>
<p>For our purposes, the first page serves as a good unique
synthetic key together with the other bibliographic info
(Journal+year+volume+issue+first-page is (nearly) guaranteed to be
unique, unless publishers do something totally crazy as having
duplicated page numbers in the same issue...). Thus, using Article
ID as the first page when there is no page is suitable for this
purpose, and we do it so far like this. A machine readable
indication that we have Article ID and not the page number is the
NULL value in the `lastpage` SQL column :).</p>
<p>For article identification we can increasingly rely on DOI
nowadays.<br>
