Discovering node properties in neo4j grap db

I'm discovering a new graph data model in Neo4j and I was wondering how to list all the possible node properties but not their value if possible.

For the relations, I found this very handy generic cypher query :

start n=node(*)
match n-[r]-m
return distinct type(r)

which return a useful list of properties you can start to use to query more specifically the graph:

==> +------------+
==> | type(r)    |
==> +------------+
==> | "RATED"    |
==> | "FRIEND"   |
==> | "DIRECTED" |
==> | "ACTS_IN"  |
==> +------------+
==> 4 rows
==> 0 ms
==>

Is there any function/expression that allows to do this but for the node properties ?

Thanks

To list all the properties of nodes in graph DB, you can try using following cypher:

match (n) 
WITH distinct keys(n) as properties 
UNWIND properties as property 
return distinct property

type() does not return relationship properties, but the relationship type.

Both nodes and relationships can have properties, but only relationships can have a type.
