There is no reason why OutputLangUtils can't encode Node.ANY as well - there is
not need for a major change to the Node contract for this. There are many
deployed applications using Jena and a change such as this could have wide
implications.
The operation .isURI() implies that the Node really is a URI node, and so
getURI() return something. It woudl be wrong to have isURI true on Node.ANY
because that node does not return a URI.
Adding isVariable() implies it's a named variable - named varibales are used to
associate values in query results. Node.ANY does not do that.
I propose we close this with "no fix" and discuss in a general context on email.

> Issue Type: Improvement
> Components: Jena

> Labels: jena, node.any

> In the javadoc it is said "A Node_ANY (there should be only one) is a
> meta-node that is used to stand *for any* other node in a query". Hence, I
> was expecting that any call to isVariable, isLiteral, isURI, etc. return true.
> Iam raising this issue because in OutputLangUtils it is not possible to
> output (serialize) a Node_ANY. Hence, I think there are two solutions to
> support it. Either we can add a small code to handle the issue in the output
> method from OutputLangUtils or we can correct the Node_ANY class to support
> what is stated by the javadoc (by overriding is* and getName, getURI, etc.
> methods).
