RE : altLabels in different langauges

Hello,

I think there was a (very) small misunderstanding. I especially wanted to react to Alistair's proposal (let's call it AnnotationLink-as-class), which seemed too complex to me, or at least too complex to prefer it to the Term-as-class one without further investigation.

I would also be very dispapointed. And indeed I think the Term-as-class would perhaps still be simple enough. But the AnnotationLink-as-class

In the Term-as-class solution you can use that, indeed. But not in the AnnotationLink-as-class one, where you have these "source" and "target" properties.

Same answer, of course

I suppose motivated developer/modelers (and I dare say I would be one of them) could consider the addition of triples without much difficulty. But in case of comparable amount of efforts (adding terms instances and related triples vs. adding annotation instances and related triples) I would be reluctant to go for the less natural one and/or the less compatible with existing reasoning mechanisms.

Agreed, it's just that I cannot refrain from sending my two cents on this "change proposal" theme.
