I'm looking forward to use NeoJ4 for some researchs. However I have to check if it can do what I want first.

I would like to build a graph that says :

StatementID1 = Cannabidiol hasPositiveEffectOn ChronicPain
 StatementID1 isSupportedBy Study1
 StatementID1 isSupportedBy Study2
 StatementID1 isNotSupportedBy Study3

This is easy to add key:Value properties to a relationship in NeoJ4.

The difficulty is that I want Study1,2,3 to be nodes. So that these can have them own set of properties.

This can be done in a triplestore where each triple has an ID like "Statment1" here. This is a matter of adding triples where the object is another triple ID.

url:TripleID1 = url:Cannabidiol url:hasPositiveEffectOn url:ChronicPain
url:TripleID2 = url:TripleID1 url:isSupportedBy url:Study1
url:TripleID3 = url:TripleID1 url:isSupportedBy url:Study2
url:TripleID4 = url:TripleID1 url:isNotSupportedBy url:Study3

For the moment I can't find how to do it simplely in NeoJ4.

I could add the DOI of the study as a property :

Study 1 :
 DOI:123/123

Then add the same DOI in the link :

isSupportedBy:
 DOI:123/123

Since the DOI is unique it could be possible to make some searchs. However this will make things much more complex.

Is there a simpler method to achieve that?

I suppose this is a database design issue.

Would a node/relationship model something like the following fit your data and make your queries easy?

  That's it but since the Cannaidiol can have positive effects on other medical conditions, we need 2 links : Statement -> Subjet and statement -> object. Yet another problem is that there could be studies that say that Cannabidiol has postive effect on chronic pain and studies that says it has no effect. So that we need to point also Statement -> HAS_POSITIVE_EFFECT, what is impossible, or double store the link name in the statment properties. Wich is complex...

  @Thib Or even link the :Object directly to the :Statement. It really depends on the data you have (or plan to have) and the queries you expect to do. And, if after a while you have a better model, you can just change it (as long as there aren't lots of other things/people depending on the database not changing).

Neo4j doesn’t support edges going from an edge to a node. Edges are always between nodes. So you’ll have to convert your positiveEffect edge to a node (as proposed in rickhg12hs’s answer) or model the positiveEffect as a non-edge (as you yourself proposed).
