Hi Margherita,

Thanks for these use cases, this is really useful. I think these are important use cases, and we should have an idea of how to represent them.

Note that originally, skos:prefSymbol and skos:altSymbol were intended to link to images, i.e. resources which dereference as jpg or png or gif. Hence the range of these properties in earlier drafts was dcmitype:Image. 

Perhaps the skos:notation property might be a more appropriate property for these types of chemical "symbol"? Or skos:prefLabel with an appropriate x- language tag?

Regards,

Alistair.
