Ordering
Not specifically a Jena question, but we'll have a requirement at some
point to order a set of triples in a given order (not alphabetical). Would
it be that we'd require some sort of ranking number attached to the triple
via a node or somesuch?

That's one way.
If the access record "War Memorials Online, accessed 10 July 2017 from
https://www.warmemorialsonline.org.uk/memorial/137280" is important then
making it a first class item in the data is usually the thing to do for
some future requirement.
Another is to use a list.

Ah, well it was a pretty unhelpful diagram.
For a given subject we will have lists of sources.
<http://heritageengland.org.uk/dataset/monuments/monument/meta/id/1000824>
ns1:website "War Memorials Online, accessed 10 July 2017 from
https://www.warmemorialsonline.org.uk/memorial/137280",
"War Memorials Online, accessed 10 July 2017 from
https://www.warmemorialsonline.org.uk/memorial/77464",
"War Memorials Register, accessed 10 July 2017 from
http://www.iwm.org.uk/memorials/item/memorial/47501",
"War Memorials Register, accessed 10 July 2017 from
http://www.iwm.org.uk/memorials/item/memorial/47502",
"War Memorials Register, accessed 10 July 2017 from
http://www.iwm.org.uk/memorials/item/memorial/47503",
"War Memorials Register, accessed 10 July 2017 from
http://www.iwm.org.uk/memorials/item/memorial/47504",
"War Memorials Register, accessed 10 July 2017 from
http://www.iwm.org.uk/memorials/item/memorial/59537" .
We could display the linked websites in a particular order which is not
necessarily alphabetical, so I'd want to basically hold an attribute for
each (i.e. A Ranking Order).
Do you think it might be a case of using a bNode for each then off the back
of that having the Source and Rank?

Matt - images (here, as multipart attachments) don't get passed on by
the list.
