Colourful problem

Friends. 
I have a problem with the colour :-) 
The case: 
Documents with applied seals... Beside the material of the seal, I want to specify its colour, using a suitable concept from the AAT Colour facet. [In the legacy records - for documents - I have a field "seal material" and one "seal colour"]. 
 
So, my plan is: 
<myDocument [E84_Information_carrier]> <P46_is_composed_of> <mySeal [E84]> 
<mySeal [E84]> <P45_consists_of> <myMaterial [E57_Material]> 
<mySeal [E84]> <P56_bears_feature> <myColour [E26_Physical_Feature]> 
e.g. 
<myColour [E26]> <P2_has_type> <aat: 300131648(i.e. chromatic colour) [E55_Type]> 
e.g. 
<myColour [E26]> <?> <aat: 300310722 (i.e. blood red) [E55]> 
 
NB. I'm converting AAT too. 
What's the right predicate (domain E26, range E55) to use, in order to say "myColour IS blood red" ? 
I could use rdf:value (domain rdfs:Resource, range rdfs:Resource), but I'm not comfortable with it. 
An advice, please...

Hi Dan! Interesting question. 
Documents with applied seals... Beside the material of the seal, I want to specify its colour, 
 
To my mind things like Seals and Ink Stamps are E25 Man-Made Features. 
Since Man-Made Feature is a subclass of Man-Made Thing, you can still attach Material. 
But there's a strong correlation between type and material: you can't make a relief seal from ink 
So I think it's better to incorporate type and material into an enumeration, using a thesauris like: 
<thesaurus/marks/wax_seal> 
<thesaurus/marks/golden_seal> 
<thesaurus/marks/leaden_seal> 
<thesaurus/marks/leaden_seal_with_machined_stamp> 
<thesaurus/marks/ink_stamp> 
<thesaurus/marks/customs_banderol_sticker> 
<thesaurus/marks/brand_burned_on_cow> (I'm sure there's a proper term for that). 
NOTE: E37 Mark is an information object so I should have used something like "seal" in the URLs above, but I'm too lazy to change that now.. 
 
In fact AAT defines some such hierarchy: 
http://www.getty.edu/vow/AATHierarchy?find=&logic=AND¬e=&subjectid=300200896 
And here is the sub-hierarchy of seals: 
http://www.getty.edu/vow/AATHierarchy?find=&logic=AND¬e=&subjectid=300028877 
 
<mySeal [E84]> <P56_bears_feature> <myColour [E26_Physical_Feature]> 
 
I don't think a Feature is something that covers the entirety of a Physical thing. 
But I consulted the scope note of Feature. Relevant excerpts: 
- "*may* have a one-, two- or three-dimensional geometric *extent*", i.e. not the whole thing. But not necessarily 
- "*portions* of particular objects with partially imaginary borders" 
- "can be .. scratches, holes, *reliefs*: so Seals are properly modeled as features, even if they have relief. 
- "*surface colours*, reflection zones in an opal crystal": so colors *are* included. But I think "colored spots/zones" is meant here 
 
What's the right predicate (domain E26, range E55) to use, in order to say "myColour IS blood red" ? 
 
I think an extension prop: P2X_has_color, subprop of P2_has_type 
 
using a suitable concept from the AAT Colour facet 
NB. I'm converting AAT too. 
Well don't. Use http://vocab.getty.edu/. E.g. the above is http://vocab.getty.edu/aat/300310722 
- The old doc is here: aat_semantic_representation.pdf 
- the new doc (coming in a week) is here: http://vladimiralexiev.github.io/aat/index.htm 
- also coming in a week is TGN 
-- 
In summary, I would model it like this 
<document> P56_bears_feature <document/seal>. 
<document/seal> a E25_Man-Made_Feature; 
P2_has_type <thesaurus/marks/wax_seal>; 
P2X_has_color aat:300310722. # blood red 
 
Or if you already have a Materials thesaurus, split it like this: 
<document> P56_bears_feature <document/seal>. 
<document/seal> a E25_Man-Made_Feature; 
P2_has_type <thesaurus/marks/seal>; 
P45_consists_of <thesaurus/materials/wax>; 
P2X_has_color aat:300310722. # blood red

Hi Vladimir
Thanks for your comments.

My mistake, sorry: I mean attached seals, e.g. www.kings.cam.ac.uk/library/archives/college/hlfproject/counties/images…;
To my mind things like Seals and Ink Stamps are E25 Man-Made Features. 
I tend to agree, for the (really) applied seals. But I asked several museum people (the data providers) and the majority see the seal a distinct part. I continue to "investigate". Now I'm inclined to let them decide case-by-case. I'm still in dounbt :-( 
Should I treat the attached seals and applied seals differently ? 
 
In fact AAT defines some such hierarchy:

Ha ! Good to know... 
 
I think an extension prop: P2X_has_color, subprop of P2_has_type 
 
Maybe...

I'll read. Thanks. 
 
I'm ingesting AAT because (hopefully) we will add Romanian terms. That's the "political" reason, but also converting it to CRM (well specialised a bit :-( is interesting.

Hi Dan!

Oh, I agree that's a Part not a Feature. It hangs by a thread! 
 
the new doc (coming in a week) is here: http://vladimiralexiev.github.io/aat/index.htm 
 
The official version is here: http://vocab.getty.edu/doc/ 
 
I'm ingesting AAT because (hopefully) we will add Romanian terms. 
 
I'm sure the Getty will be interested to hear about this, even if it's only a small part. 
Currently there are only 17 Romainan terms (all in TGN, none in AAT): 
http://vocab.getty.edu/sparql 
select * {?x dct:language gvp_lang:ro} 
The last 3 days I've been at the International Terminology Working Group, and we heard reports on various translation projects, from Chile to Taiwan.

 

In the 32nd joined meeting of the CIDOC CRM SIG and ISO/TC46/SC4/WG9 and the 25th FRBR - CIDOC CRM Harmonization meeting  the crm-sig decided that this issue is covered by the issue 255. So this issue is closed.
