A few points:
* OSM standard is British English. Shopping Centre is standard British
English for an enclosed pedestrian space with lots of shops. Historically these
have been covered, but this is changing to a simulated street environment (in
UK Liverpool One the Arc at Bury St Edmunds are recent examples.
* Use of the shop tag is inherently problematic. These are not shops
but retail areas. At the moment whenever I do any kind of retail analytical
query I have to do AND NOT IN (shop='mall'). I would prefer to use
landuse=retail with retail=mall or retail=shopping centre etc. We certainly
don't tag a centre of a village with a few shops as shop=village_centre.
* shop=mall is more widely used, and although predominantly US English
is not likely to be a confusion which shopping centre obviously is from prior
posts here. Some of the examples cited would be usually called "Retail Park"
for what I think is typically called a strip mall in the US, and "Shopping
Precinct" for a smaller pedestrian area, often with only minor weather
protection for shoppers. The latter are dying on their feet in the UK as they
cant compete with the "Retail Park" or have a poor selection of shops.
* I attempted to provide a fairly detailed typology of these various
types of retail area in a blog post last summer (hopefully with some useful
illustrations). However I think this could be expanded substantially especially
with more examples from different countries. See also the typology used by a
specialist Retail GIS Analytics company which features at the start of the
blog. Some (largely those featuring the word Parade) may be very UK specific,
but most are suitably general. There are also a couple of slides relating to
the issue in my SotM-Baltics presentation (#10 in particular).
* I noticed whilst attending SotM-Baltics last summer that true
shopping centres/malls are very common in the main towns in Latvia and Estonia.
Presumably they are a favoured way of adding new retail premises. Unfortunately
many of these have 3 or more shopping floors and are even harder to map than 2
storey malls.
* The two main shopping centres in Nottingham have had all the retail
outlets mapped. There are many issues as to the best way to map shopping
centres/malls but it is clear that if one wants to be accurate about the
provision of shops in a town it is essential that this is done. They are also
difficult to map because most establishments are access=customers and do not
allow photography.
* I mapped an area E of Pittsburgh, PA which has a nice variety of
different kinds of out-of-town retail areas (a mall, Monroeville Mall, several
strip malls, smaller areas, numerous car dealers). Unfortunately we don't have
active mappers in the area. If anyone can identify a similar location in the US
where there are active mappers and useful pictures this would really help sort
out the kind of typology we need.
I did start drafting a blog post on this very issue mentioning many of the
points above, so it's probably time to finish it.

To me analyzing the given examples it seems as if a mall was necessarily a
closed place while a shopping center would/could have outdoor connectivity.
They appear to be similar as they both have several independent shops and
collective facilities like toilets and parking. Maybe a mall has to have
restaurants and other eating facilities, while a shopping center doesn't have
to (but could have). I think small sets of shops with collective parking won't
qualify as "mall" but they might constitute a shopping center.
