Thanks, Katie. I see that the external ID datatype
does not work as planed.
At least I thought the original idea was to clean up the UI by moving
hard-to-understand string IDs to a separate section. From the discussions on
these pages, I see that the community uses criteria that are completely
unrelated to UI aspects, but have something to do with the degree to which
the property encodes a one-to-one mapping. I guess this is also valid, but
won't be useful for UI purposes. I will need to use another solution for my
case then.
My2c, sorry if I'm going offtopic.
My impression on some properties is that we're probably
underestimating some problems that are independent from our will, such
as:
* the possibility that the original catalogue might have some
duplicates, and we can actually help the original catalogue to correct
this issue;
* the possibility that the Wikimedia approach and the catalogue's
approach might bring one of the two sides to define something as two
different things, while the other sides comprises it as a whole (for
example, "palace+gardens");
* the possibility that some identifiers *are* standardised, but the
authority did not published a single catalogue, leaving the single
institutes to care for their own catalogue (for example, the
International Standard Identifier for Libraries and Related
Organizations, aka P791);
* and so on.
Particularly the ISIL one is an important example to me, since I work
for the Italian institution that actually is entitled to conduct the
census of Italian libraries and assign the ISIL code to every and each
library in Italy. There is no single world catalogue of that
identifier? I really don't see it as a problem, as long as there it is
at least one national authority that does that job. We're probably
underestimating the fact that not everything has been standardised at
a world level - and that we can live with that just fine.
Probably the threshold we set up for the conversion is too high, and
this might be one of the causes why the whole process has slowed down
to a dying pace.
