Standardise a baseIRI parameter on import

[tpluscode]

As discussed in rdfjs/rdfxml-streaming-parser.js#41, @rubensworks proposed to add a parameter to the import method so that it's a standard feature of all parsers to accept a baseIRI

const parser = new MyParser()

parser.import(stream, { baseIRI: 'http://example.com' })

This is already implemented by a most and would nicely complement the analogous param on the constructor

[rubensworks]

Just to note, several parsers (N3, RDF/XML, JSON-LD, RDFa) have this parameter on the constructor, instead of the import method.
It might make sense to have a standard for what as well/instead.

That is already there: https://github.com/rdfjs/stream-spec/blob/master/index.html#L155

And not "instead of". Those are separate features

Oh, I completely missed that, then my implementations adhere to it by coincidence 😄

Just wondering if this will not be too confusing for people, as there would be two places to set a baseIRI.

I mostly use the Sink returned by a sink map, typically constructed by @rdf-esm/formats-common or even @rdfjs/fetch. This way I never call the constructor myself and thus have no opportunity for setting the base.
