State predicates (and maybe subjects/objects) by their rdfs:label values

[andrawaag]

I am currently trying to write shape expressions on Wikidata, specifically for disease, genes and proteins. Wikidata uses property numbers as predicates. (i.e. wdt:P31 = "instance of", wdt:P279 = "subclass of", wdt:P699 = "Disease Ontology ID, etc). It would be convenient if it would be possible to state predicates (or maybe even subjects and objects), but their labels. Would that be possible?
