When I wrote the wiki page for Enhanced-API, I ended up using all the words I
had spent on the hyperrelationship example, so I decided to keep the original
page alive, but link it to the enhanced API page.

You raise interesting questions, most of them very much related to the work I
did on Enhanced API.
Let me start with the distinction between Node and Relationship, which in my
opinion too is a bit artificial. I understand when creating a graph database,
it is helpful to have something like
That's a great summary, Niels. Very similar to how we've applied Neo4J here at
ThingWorx, though we've done most of the type system work (nodes and
relationships are all typed/subtyped) in our application domain layer. A few
other items that we leveraged in our implementation that you may
We're using Neo4J to model the real world with things here at ThingWorx as
well. See my responses to Niels for some specifics.

is it possible to do smth like the following

RETURN source,target

Right now it's not possible. It's a planned feature, but it's not done.
It will not make into 1.5. That's all I know right now.

Great thoughts guys!
I think it would be interesting to break out the Enhanced API from
graph-collections, rename it into something better (we can think of a
name together) and provide a more fully fledged example that we can
document and evolve.
WDYT?

Enhanced API grew out of a couple of classes I added to make
IndexedRelationship work more easily (not exposing comparators), but it is
essentially a separate component. Giving it that status would help other's
improve it. Having laid some of the ground work, I feel it needs other people's
done.

Subtyping of relationship types sounds like the cure to my problems.
When creating a relationship IS_A_JANITOR_OF, will a corresponding
relationship type IS_A_JANITOR_OF-relationship-type automatically be
created?
If I have a simple relationship can I then ask which relationship types it's
type
I too think that much of the type system of the application actually belongs in
the application domain layer. There are so many trade-offs that can be made
that a one-size-fits-all typing of a graph is not the way to go. This is why I
decided that enhanced-api should only provide the nuts and
Subtyping works as follows in Enhanced API.
When calling getRelationships(RelationshipType, Direction) or any of its
alternatives, the API looks up all subtypes of that relationship type and then
call getRelationshipTypes(Direction, RelationshipType and its subtypes). All
you need to do is
Thanks!

Quite wrong.
IS_JANITOR_OF will stick you into a boxed node ordinal.
What you really want when modeling the world is to only capture the
semantic relationships themselves. IS_A being a core semantic
relationship. I am a janitor. He IS_A janitor. What is a janitor ? What
properties does a

Unfortunately, most of what I describe as best practices in modeling
semantic relationships has not been written well ENOUGH in most books.
However the W3C community lists such as SKOS and RDFa have many experts
that have deep knowledge around those best practices. Asking your questions

What if:

The school HAS_A janitor
How do I denote that Joe works as I janitor at that exact school?
Do you see other problems in the notation above?

Andreas,
thanks. can't wait for your result.
one correction on my list:
Retrieve a certain types of relationships of a node should be faster
than retrieve all. i mis-read the source code in NodeImpl.java, in
which private volatile RelIdArray[]

we are experimenting with that feature, namely, not forcing a flush()

flushing. You potentially
