I'm converting a JSON-LD input to RDF using Jena:
Model m = ModelFactory.createDefaultModel;
String str_reader = new StringReader(json.noSpaces)
RDFDataMgr.read(m, str_reader, "", RDFFormat.JSONLD.getLang)

I want to be able to have a custom serializer for String Literals. My end goal
is to convert a plain String literal to a xsd:date or xsd:dateTime Literal
whenever a desired format is found.
Look at StreamRDF and RDFDataMgr.parse
(or build your parser for more control with RDFParser.create())
All parsers send their output to a output to a StreamRDF.
RDFDataMgr.read uses a StreamRDF that puts triples/quads into a graph.
StreamRDFs combine so you can build a pipeline
Parser -> convert strings -> store in graph.
Streams as well so works for large data if the syntax streams (JSON-LD
does not).
I know this is handled by jsonld-java which in turn relies on jackson. Is there
anyone who can give me a hint on how to add this type of custom serialization?
Jackson is the JSON parser.
jsonld-java is the JSON-LD algorithms.
What you seem to want is triple processing and be syntax agnostic.
