I'll comment on Peters last email before going back and replying to Nolans big one. The work Peter refers to is some changes I have made to support the changesets as a graph, which is a step towards supporting applying changes to the OSM model, something several people, including Nolan, have reque

Re: [Neo4j] FYI: Digest of our late night discussion (around domain modeling) with Mark Nijhof

If I understand you correctly, then you'd create the node upfront, and don't pass it to the code that creates the relationship but instead lookup the node using the index (or a relation from a e.g. type node). If you want to create it on demand, just add an index lookup before creation. Cheers

Re: [Neo4j] Getting started with Neo4J Spatial

Also, on the note of file sizes - Craig is on his way to implement explicit modeling of changesets and users in the graph, taking them from String properties on the nodes to explicit relationships. This, together with the ShortString improvements, should get down sizes a lot (I saw with only Short

Re: [Neo4j] Getting started with Neo4J Spatial

Guys, I have started looking into the OSM imports. basically, the main problem is to fast insert the nodes into an exact-matching index, and then, when going through the ways, look the nodes up by OSM-ID in that index in order to conenct them to the ways. Lucene is not very good at that, so I have

Nolan, The first experience with Neo4j Spatial was with the texas.osm file. I imported it on my notebook & I think it took 15 hours, if I remember correctly. I quickly decided to play around with just Austin for the time being. If you'd like, i can zip up my Austin file (just Austin, not any of th

Re: [Neo4j] FYI: Digest of our late night discussion (around domain modeling) with Mark Nijhof

Hi Michael, A continuation :) When I add a relation to a specific type node to indicate what type the node represents then I need to make sure that this node is unique. So the question is should I create the different type nodes before hand, or can I create them on demand? And the concern is cons

Re: [Neo4j] Neo4j rest server indexing

Hi Francois, I just joined the list recently and had the same question. And as far as I understood, the REST API does not provide that feature yet. You can easily add a neo4j plugin to implement it. But I had some trouble doing so. But in the end it worked. I haven't found the time to document my

Re: [Neo4j] Better support for large property data

Does it go without saying that when this is implemented that a neo instance would still be able to open a graph from a prior version? Would this be an automatic one-time conversion, or would there be a utility that would convert from one format to the other, or something else? Thanks, Paul Jac

Re: [Neo4j] Better support for large property data

I was wondering about one part of your original comment, that we might want to exclude large 'blobs' from the transaction log. Does this mean the main difference between the current ideas for long strings and large blobs is that the strings will be transaction safe, while the blobs are not? In addi

Hi, Tobias. I had a few posts on this a couple weeks back. Similar ideas to what you've suggested (in fact, we've done a blog, wiki, and forum engine using Neo as the datastore). A few other design criteria I'd throw into the mix: - Pluggable BLOB/CLOB storage providers (e.g. FileSystem, Native

Having tackled short strings, I feel up for taking a stab at long strings, and large binary data objects. I know that Rick Bullotta is really interested in this, and I can imagine others wanting to store large properties as well. I would love to get your input on the ideas I have, as well as heari

Hi, a small issue with the neo4j webadmin (1.3.M02). In the data tab if you want to create a new property the "value" input box goes red and the input is not saved. The only way to get it to work is to create a property that has numbers for key (such as 123)!?! Then the property is saved. Alfred
