@base <https://ontotext.com/knowledge-graph/>.
@prefix OTKG: <https://ontotext.com/knowledge-graph/>.
<researchProject/(acronym)> a s:ResearchProject;
s:sameAs <(wikidata)>.
This is rendered as the CURIE OTKG:(wikidata), i.e. the field (wikidata) is interpreted as a URL relative to @base.
This makes sense for templated URLs like <researchProject/(acronym)> because the start it not a URL scheme like http:.
But for a URL that consists of a field alone, it's reasonable to assume that will be an absolute URL.
It's the RDF parser that decides that (wikidata) is a relative URL. How to fool it into not using @base?
I could fake it as https://(wikidata) but that's ugly as hell: how could I know that's the right URL scheme?
If I fake it as /(wikidata), that would use the host from @base, and <https://ontotext.com/(wikidata)> is even worse.
I think it's the safest to EXCLUDE the @prefix that is equal to @base.
(The reason I used it is because GraphDB remembers prefixes as namespaces, but does not remember base.
So OTKG: is used to shorten URLs when displaying resources.)
