Le parent an individual and a, b two individuals linked to parent via the properties hasChildA and hasChildA respectively. Now let f be an individual linked both to a and b via the property hasFriend.

parent hasChildA a
parent hasChildB b
c hasFriend f
c hasFriend f

by serializing the parent with the jsonld object mapper and then deserializing it, the following exception is thrown

cz.cvut.kbss.jsonld.exception.JsonLdDeserializationException: Node with IRI http://example.org/f cannot be referenced, because it has not been encountered yet.

Jackson allows ignoring a property by directly annotating it with JsonIgnore, but also ignoring multiple properties by listing them in the JsonIgnoreProperties annotation on class level.

Note that JsonIgnoreProperties can also be used directly on attributes in which case it behaves similarly to JsonIgnore. Consider supporting this behavior as well.

Attempting to serialize a simple collection of URIs (would be the same for String or any other type presumably) produces an invalid JSON. For example:

["http://onto.fel.cvut.cz/ontologies/slovník/datový/psp-2016","http://onto.fel.cvut.cz/ontologies/legislativní/sbírka/183/2006"] {"@context":{},"@graph":[{"@id":"http://onto.fel.cvut.cz/ontologies/slovník/datový/psp-2016"},{"@id":"http://onto.fel.cvut.cz/ontologies/legislativní/sbírka/183/2006"}]}

Note that this happens when running serialization with context.
