Hi Anders, this is a great post! Another interesting aspect of graph databases is IMHO thte absence of any required relationships or attributes per se (of course enforcable with higher level wrappers like the meta neo4j project). I feel it gives a lot of flexibility to the data modeling and above all does not require one to upfront define all possible future properties and relationships, just to avoid major RDBMS updates later. This leads to sparse tables and a lot of error and null handling code - not exactly domain friendly.
Of course there is a downside for this flexibility, the handling of traversals in a more dynamic manner via Neo4j Traversers or SparQL or other new query paradigms that can accomodate this kind of semi structured layout. Basically I can see all the arguments of RDF and the GiantGlobalGraph apply to Neo4j and other data structures, but without the cumbersome RDF-String based (lack of) programming model to do real world applications. Neo4j - the Giant Local Graph :) /peter Open Hearts, Open Minds, www.OpenCauses.org.
