Dataset.getUnionModel()

Dataset.getUnionModel() excludes the default graph. Would it be appropriate to include the default graph in this method, or to add an additional unioning method to the Dataset interface which includes the default graph? It seems like an oversight, but maybe there was a reason for excluding it?

The @vocab prefix is dropped by Jena when parsing JsonLD. An empty prefix is correctly translated into @vocab during serialization, but is lost during deserialization. Below code demonstrates the point. public static void main(String... args) { String base =

Re: potential new API Was: Immutability

I just want to mention that it was not my intent to derail progress on Jena-1391 (https://issues.apache.org/jira/browse/JENA-1391) by raising the issue of immutability, particularly if immutability would be implemented via a new API. I don't think it should be considered a blocker to that

Re: consistent blank id values from RDFConnection

My understanding is there's nothing wrong with maintaining labels among multiple calls to a single graph. The danger would be the risk of maintaining labels among calls to multiple graphs. At least, that's what I get out of this SO answer:

Immutability

The subject of immutability was raised in JENA-1391 (https://issues.apache.org/jira/browse/JENA-1391). Specifically, the `getUnionModel` method in Jena 3.4 returns an immutable model view, and the implementation of the aforementioned story includes methods that will return an immutable dataset
