It encourages non-transactional operations. I think the batch-ing should be

In my opinion, the current syntax reminds me of SQL, which is a good

With REST, you have a separate server. Thus multiple applications
can use. Or you can access it directly through normal web browser
to fix your data.
Or even run background jobs against that server. All that is
not possible with native.
I wouldn't say that. It's not possible using Neo4J APIs
Actually that is true with many technologies.
to provide a REST-Endpoint Neo4j-Servers you can use:
* jruby with sinatra/rails
* python
* as you said SDN
* playframework and scala
* clojure (and whatever rest-framework on top)
* or even pure netty based high performance servers
* or other java
Why not take a look at RingoJS? Would be uber easy to integrate native Neo4J
APIs.

Hi Frank,
this is really weird. Your server is missing the exploratory URL for the
reference node.
The (Spring)RestGraphDatabaseService uses this URL to get the URL for the
ReferenceNode.
I don't know why your sever is missing that.
I just downloaded 1.5 community for unix and started the
Interesting. I did create and delete a few nodes manually via the Web interface

that. In any case, it seems to be working now that I reinstalled the server
