If I want to get the following
g.V(0).out('Friends')
and
g.V(0).in('Likes')
in one call what is the best way to do this?

Kan,
if you need to collect results, just empty the two different
traversals into a result List (last statement is for returning it, if
you use http://docs.neo4j.org/chunked/snapshot/gremlin-plugin.html
g.addEdge(g.v(1), g.v(2), 'Friends')

In the document (15.7.6) the example of adding a node to index by a POST method

Andrew,
do you have the URL to the documentation you are looking at? Is it the
same version as the database version you are using?

Thanks
fyi: the syntax for this using my .net client
GremlinScript script = new GremlinScript();
script.Append(results = [];)
.Append(a = ).gV(ID).Append(;)
.Append(a).In(RelationshipType.Like).Filter(!it.getProperty('{0}'),
NodeProperty.Delete)
.Append( results;)
Hi Andrew,
In the latest snapshots the API has changed, see:
http://docs.neo4j.org/chunked/snapshot/rest-api-indexes.html
So either ensure you're using 1.5M01 if you want the old behaviour, or a
snapshot if you want the new behaviour.

Kan,
I also pushed an example for this which should be online under
http://docs.neo4j.org/chunked/snapshot/gremlin-plugin.html in some
hour, when the build is through. If you care, feel free to check it
out.

Hi Daniel
I’ll try to stop by. My friend and I built a startup using Neo4j and we’ve
had a great experience so far. Is there RSVP list?
Just stop by. There is no RSVP.

Very cool!
Btw, just added parameters to the Cypher REST Plugin too, since
Andres pushed them into the core parser.
http://docs.neo4j.org/chunked/snapshot/cypher-plugin.html#rest-api-send-queries-with-parameters
which will mean the mode of submission is the same for Gremlin and
Cypher.

I just wanted to share the news around the next version of the Spring Data

First of all - the library will be renamed to Spring Data Neo4j and the next
release will be version 2.0

Vivek, Andreas,
very interesting design! Let's see how this works out in the longer
run - if it proves useful in other scenarios, maybe this is a good
pattern to propagate to others, and to pull down into some Java
library in order to be usable from other stacks, too!

Hi Jim,
Thank you! I'm using 1.5.M01 version. Just out of curiosity, how did you add a
node into the index in the 1.5.M01 version?
I'm downloading the SNAPSHOT and will try again.

integration tests, so this code has been running against a server. In

Hi Peter,
I downloaded the SNAPSHOT version and looked into the manual. It is different
from the one in the 1.5.M01 version and it looks very nice as well as useful.
I modified my code to Post the Json object to the index and the node was
successfully added. Thanks!

Peter,
i installed 1.5-SNAPSHOT and the call g.v(0).out('Friend', 'Like') does work
however, when installed the update the server would not start using my 1.4
data files. is this because of something i did incorrectly during the
update?

Kan,
There are incompatible store changes that we are right now QA-in the upgrade
process for. If you want to upgrade, i advise to wait for the release with
instructions. Otherwise, a new import is the best choice right now. Would
that be ok?

for now it is not an issue for me to update on my development server but if
you could give an idea when the release is due out that would help. i am
not in a hurry for the update since current functionality satisfies my
business needs.
