[Neo4j] Neo4j Internals

[Alexandre de Assis Bento Lima]

Hi,

I couldn't find any information about Neo4j storage system and other internal details on 
its website. Searching the web, I found:

http://nosql.mypopescu.com/post/1396301953/neo4j-internals

which gives many details and seems to be very good material. My question is: as the 
articles were published on October, 2010, are they still up-to-date? Neo4j 1.5 has the 
same implementation?

Thanks a lot and special thanks to Chris Gioran, who wrote the articles.

Alexandre.
