You don't gain much by storing the state in a closure unless you need to
guarantee that the user of your code can't access it, which with immutable
data structures isn't often necessary.

You might be interested in the JSON-LD w3c standard which defines

Apache Jena is another good choice for a graph database. It has the choice
of an in-memory database, memory-mapped file database (optionally with ACID
transactions), or mapped to a relational database. It can also run as a
separate database server. There is a procedural java API and the standard
OWL has several levels of increasingly expressive but general inferences.
Much of the domain could be represented in OWL (classes (i.e. sets),
instances (i.e. set membership), relationships with domains and ranges,
etc.), but there would still be a need for the domain-specific inferences

I've used javaspaces a fair bit in high-flexibility situations, although
not in a truly high-scale situation. I am aware of truly high-scale
implementations. Just be careful extrapolating from one case to another.
Contact the apache river folks for detailed reports of javaspaces in
high-scale..
Paul,
Another concurrency model I've used a great deal is the tuplespace model,
specifically javaspaces. This is an often forgotten model that has a lot to
offer with a high expressiveness to complexity ratio.
Not closure specific, so feel free to contact me again directly if you're
interested
