[Neo] Author Neo4J Books - Packt Publishing
Hi All, I am writing to you for Packt Publishing, the publishers of computer related books. We are planning to expand the catalogue of our books on databases and are looking forward to publish some books on NoSQL. Currently we are inviting people interested in writing NoSQL books for Packt. This doesn't need any past writing experience. All that we need is an expert subject knowledge, a passion to share it with others and an ability to communicate clearly in English. So, if you love Neo4J and fancy writing a book, send your book ideas to us at aut...@packtpub.com. Even if you don't have a book idea and are simply interested in writing a book, we are still keen to hear from you. More details about the opportunity are available at: http://authors.packtpub.com/content/inviting-open-source-nosql-databases-fanatics-write-packt Thanks Kshipra Singh Author Relationship Manager Packt Publishing www.PacktPub.com Skype: kshiprasingh15 Twitter: http://twitter.com/packtauthors Interested in becoming an author?

Re: [Neo] neo rdf
When I think about it it should be a simple and fast operation to do that, i.e. change the value of only one node and reindex it. Unfortunately there's nu tool for such an operation, but I can see what I can do to create such a tool for you. Allright? 2010/5/5 Lyudmila L.

Hi Kshipra, would be awesome to write a book. Mostly, our problem is time. Is there anyone on the list wanting to contribute or take a stab at a Neo4j book?

[Neo] Performance
I have done some simple performance comparison between neo4j and babudb (http://code.google.com/p/babudb/), because i use babudb (which users the same architecture as Googles bigtable) as an IndexService for neo4j in my object-graph-mapper. (check out the source for the BabuDbIndexService from ogrm.org) The results aren't that exiting, but updates are about twice as fast in neo4j than in babudb. Reads are equally fast, with babudb having the slight upper hand. Using babudb can therefore be seen as a good indexing service for neo4j! (Thats my conclusion, feel free to ignore) I can read 20 objects in about 4 seconds for both frameworks, including node wrapping and content deserialization (payload of 100bytes, cold cache) (My computer is really slow though) I think that is really fast! I wish i had learned about neo4j earlier though! :) -atle ___ Neo mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
Re: [Neo] Performance
Mmh, very interesting! What would be a good usecase for using BaduDB alongside e.g. Lucene with Neo4j? Would be nice to make a good example of using a different index than text together. That would open up for a number of possible scenarios, e.g. with CouchDB, Cassandra and others, that have a number of interesting capabilities that could be combined with the graph approach! Good work, wil check out the code for ogrm.org. Also, the link on the dependency page points to neo4k.org which does not exist :) Cheers, /peter neubauer COO and Sales, Neo Technology GTalk: neubauer.peter Skype peter.neubauer Phone +46 704 106975 LinkedIn http://www.linkedin.com/in/neubauer Twitter http://twitter.com/peterneubauer http://www.neo4j.org - Your high performance graph database. http://www.thoughtmade.com - Scandinavias coolest Bring-a-Thing party.

Re: [Neo] Performance
Very cool! I'm getting interested in implementing an alternative to a index service on top of lucene, and babu DB could maybe be a good option.

[Neo] NamespaceRange
Today I added the class NamespaceRange to the meta model module, to model relationships from a class to a namespace. It doesn't do much more than state that a that a particular class can have a relationship with a namespace (any namespace), so implementation-wise this is really a minor addition.

[Neo] triples store loading
Hi, I am testing the neo4j with dbpedia data. When I am loading triples in the form (URI,URI,URI) the speed is good ( 10 mln in 2 min). The loading URI,URI,LITERAL is very slow. The Literal is mainly chunks of text. For example shortabstract_en.nt with 2943434 records took 6.4 hrs to load. The file size is 1194900107. Is it possible to optimize the loading of literals or it is better to store abstracts somewhere else and keep pointer to some verbose text in neo4j? What is casing the dramatic difference in loading of the verbose literals? Thanks, Luda ___ Neo mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user

[Neo] Neo4j Python REST Client
I sent this notification in the blog post about the announcement of Neo4j REST Server [1], and Anders Nawroth suggested me to send it as e-mail to mail list. I had some problems to setup Neo4j in Linux in order to code in Python, so I decided to use the new Neo4j REST Server. However, WADL is too much hard and its syntax in python wadllib hasn't compatibility with current ne4j.py syntax. Thus, I decided to start a implementation of Neo4j Python REST Client wich the same syntax of neo4.py. The idea is you can, in the future, type: $ graphdb = neo4j.GraphDatabase( "/neo/db/path" ) Or the next is you can use the REST Server $ graphdb = neo4j.GraphDatabase( "http://localhost:"; ) By now it's a pre-alpha status, but I think in some days it will be whole functional. You can find the GIT repo here [3]. Any comment will be welcome. Regards.
