Hi all,
I've been continuing my experiments with Neo+MusicBrainz and am
working on dumping the whole postgres database into Neo. That's quite
a lot of data, requiring something like 5 GB in postgres tables. My
guess is that a full dump to Neo would be quite a lot bigger than
that, perhaps several

Hi again,
I was going to hear with you all about best practices for dealing with
what can be described as "fragile typing": Given the relationship
REMIXED going out from an artist, it's possible that the target node
is either and album or a single track. How do I solve this?

This question may reveal some ignorance on my side, but I'm going ahead anyway.
Is there anything which makes it a bad idea to have several different
enums implementing RelationshipType and using these for different
relationships in neo? The reason in my case is that some relationship

I think it would be a good idea to provide an example pom.xml on the
wiki which gets the neo dependecies and shows how to include those
with packaging.

so easy task in the jungle that is

It actually does compile with javac, it's just maven that isn't happy about it.

Hi again!
I've hit my head against the Java wall for a while, and then some
again with Python. What I'm doing is basically map to put MusicBrainz
data (artist MEMBER_OF band, album MASTERED_BY artist, etc) into Neo.
I don't need an index for searching, as MusicBrainz already has an XML
webservice
Just kidding, it's just me. Since you do have a wiki, I'm leaving
comments on some things on the Talk pages, so I hope that there is
someone who actually checks these from time to time.
