1.Does Neo4J support *unique property* (Node/Relationship)?
Right now there is no native support for that, you have to implement it on your
own - define the properties that are unique and then write an getOrCreateNode
method and/or endpoint that exposes the following things:
- query the index for the property
- if it returns something return it
- open tx
- grab write lock on a dedicated lock node (e.g. by removing an non-existing
property)
- query the index for the property
- if it returns something return it
- if not create the node and add it to the index
- close tx
It might be added to Neo4j at a later time in the form of a unique index type
(or differently).
2.How can I wrap a Node in a MyClass and using it with Rest services?
what do you mean by with rest-services ?
If you mean something like object graph mapping in the server - you might the
existing language bindings to map objects to the graph using unmanaged
extensions (Spring Data Graph, jo4neo) or the (J)ruby-script-extensions
(neo4j.rb).
3.Can I use in MyClass some JPA annotaions?
So if you want to have some cross-store persistence (graph + JPA) then you
should look into Spring Data Graph as this supports that mode explicitely.
