RE: how to: ordered collection of a Concept

Hi, all,
I may be answering out of the bigger context here. Just my two cents.

1. Orders of children issue is actually the issue of orders of siblings (the related concepts at the same level). We have raised this issue before to SKOS. 

Orders of siblings is necessary in a hierarchical classification system. Usually a notation scheme takes care of it.
Any notation has both a semantic value and an ordinal value:
The semantic value of a classification number is the subject or concept it stands for, e.g., 610 Medicine (DDC).
The ordinal value of a number of code places the subject into its determined rank in the scheme.
There are about 10 common ways used to decide the orders of siblings (coordinate classes). 

In thesaurus' multilevel formats, the siblings are often only displayed by viewing the broader term. The order of the siblings are not as critical as that in a classification or taxonomy. 
However in some thesauri, the hierarchies are much deeper than others and the whole thesaurus is highly-structured, such as AAT and MeSH. 

2. A related situation is the not-trully-poly-hierarchical cases. In AAT, one can see a concept always has a preferred parent, while in many cases also an 'additional parent'. So, it is not simply indicating one concept has two parents. It has to indicate which parent is preferred. 
See example in AAT: ID: 300265026 loutrophoros-hydriae. 
In TGN: ID: 7010273 Saint Petersburg (inhabited place). 
(The 'preferred' situation of parents is all coded clearly in the Getty vocabularies. )

Hello Vladimir,

Can you give an example illustrating the problem and approach you make with equivalentArray?

Thanks,

Kind Regards,

Johan De Smedt
