Reference node concept

[fli.rpx]

Hi,

Reference node is a bit confusing to me. How do you create a reference node with cypher?

Seems like you don't need to have a reference node, because you can just create a node and give it type.

Can anybody explain the concept or point out a documentation?

Thanks in advance,

Fudong

It will go away, relic from old times

Yes,
Finally. We just need to get the deprecating pull request into master first :-)

What's the timescale on the deprecation/removal of the reference node? Just wondering so I can plan to deprecate get_reference_node in py2neo at the same time...

Normally,
we try to have a time lag of 2 releases from deprecation to possible
removal. So if this gets deprecated in 1.9, we could remove it in 1.11

Cheers,

Is there some online documentation on recommended patterns to use instead of the reference node? I know that I, for one, used the reference node for almost all data structures, very much like using '/' in unix. Without the reference node, I assume that all starting points need to be specified by node id, which should be obtained from an external source. I expect in most cases the external source will actually be the included lucene index, unless the app decided to add some other persistence feature. In this case perhaps the 'recommended pattern' would be a description of using lucene for start nodes. I believe this is already the case in most cypher examples, but perhaps not for embedded java usage.

There's also some more discussion about it in this thread:

You are correct -- use indexes instead.
