The problem is that I wish not to use altLabels for scientific names, because the concept may have actually many more others altLabels... In fact i wish that people while indexing or searching documents, they could use a common name OR a scientific name based in their needs (a document on a receipt of potato or a scientific treaty on the species).
In a well-structured indexing and retrieval system with a linked thesaurus, it should be possible to retrieve documents by searching on preferred _or_ non-preferred (alt) terms. That is the reason for having altLabels. The "preferred" term is somewhat arbitrarily chosen (though for this purpose we try to choose the term most likely to be sought), to act as a label for the concept and to link it with documents being indexed.
If an indexer seeks to use an altLabel when linking a concept to a document, the system should automatically use the prefLabel in constructing the link. It may or may not tell the indexer that it has done this. (It may in fact use a concept number or other code rather than either of the labels.)
If a searcher searches with an altLabel, the system should automatically substitute the prefLabel in constructing a search statement. It may or may not tell the searcher that it has done this.
Two other issues arise:
A. If the need is to display lists of documents grouped under subject labels, optionally using either common or scientific names, then you will have to give the labels a type attribute, as has been suggested, so that the correct one can be chosen in each case. This may not be practicable, however, because:
(1) many organisms do not have common names, or have several common names, and there is often not a one-to-one relationship between common and scientific names;
(2) listing documents under individual thesaurus terms is not usually sufficient to produce a useful list. A useful classified display normally requires the pre-coordination of more than one concept (e.g. "potatoes : diseases" or "potatoes : prices") and SKOS does not yet provide for pre-coordination.
B. The "SKOS eXtension for Labels (XL)" provides at <http://www.w3.org/TR/skos-reference/#xl-label-relations> for the expression of relationships between different label types. We have done the same thing in the British Standard DD8723-5 data model at <http://schemas.bs8723.org/2008-06-03/DD8723-5/Model/Model.jpg> which provides for the equivalence relationship to have a "role" attribute. Example 91 given in the SKOS-XL document shows how one label can be shown to be an acronym of another, but the relationship could be specified as "common name / scientific name".
