Hi Kriti, I can comment on a few things, especially neo4j-spatial:
- Neo4j is certainly good for social networks, and people have used it for that, but I personally do not have experience with that so I will not comment further (others can chip in where necessary). - Neo4j-Spatial is good for performing some spatial queries on your domain data. So you start by modeling your domain however you want, and then when you want to start using neo4j-spatial, just add all nodes that have spatial components (eg. location) to the spatial index and they will be available for querying. The SimplePointLayer class has support for querying by proximity, which sounds like what you want. You can also query with a filter on properties (so only nearby objects matching some other criteria). - I do my neo4j-spatial development in eclipse, so there should be no issues for you using eclipse. Just use m2eclipse, and add the dependency to your pom.xml. The current version o neo4j-spatial requires neo4j1.4, so if you are using older neo4j, you might need to make minor changes. - Neo4j is not optimized for storing BLOBs, so while it can store images as byte[], it is advisable to rather store a reference to the image (eg. URI), and store the image in another way (filesystem, other database, etc.) Regards, Craig On Wed, Jun 29, 2011 at 2:06 PM, kriti sharma <kriti.0...@gmail.com> wrote: > Dear Users, > > I am developing a time capsule DB engine using Neo4j as a database. > I intend to develop three scales (temporal , geo/spatial and > egocentric/personal relationships) in the db structure. > for the geolocation part, i would like to be able to query upon a location > keyword and also some nearby places/photos/people that i have in my DB. > > Do you think neo4j spatial will be a good choice for such a spatial scheme? > I have developed a timeline in the usual neo4j using timeline feature.
