I suggest avoiding spaces in `{year ^^xsd:gYear}` --> `{year^^xsd:gYear}` - same with language `{description@en}`

It will make the annotation feels more like a single annotation rather then broking it down in 2 pieces
See what we do in xls2rdf converter e.g. https://xls2rdf.sparna.fr/rest/doc.html#generating-multilingual-values

I agree, but this slightly complicates parsing - for now we have universal divider for the terms in the annotations and it's quite a consistent pattern
