I'm trying to export Neo4j graphs into Turtle format but can't find any resource.
There have been lots of discussions and some plugin tools for importing different kinds of files into Neo4j, but not much for exporting (except into csv or json). Can someone point me to somewhere? Any hint is appreciated!

I need to do a partition of 2 components with METIS algorithm on a Gephi's graph but I don't find the way to do it. Apparently METIS use .graph files but Gephi doesn't have an option/plugin to export graph in that format.
I'm using this library for METIS partitiong: http://glaros.dtc.umn.edu/gkhome/metis/metis/overview
Finally I could do it by exporting the graph to GML format, then I opened it in python and with this library https://metis.readthedocs.io/en/latest/ I could run metis
I have built a graph in Neo4j 2.2.0. I have validated it by using Cypher interface querying etc. Now I want to import it into Gephi 0.8.2. I am using neo4j plugin (not sure of its version. Its downloaded through the tool)
When I try importing my neo4j database it gives blank error popup, no information on it. I tried to import defaultdb which comes with neo4j, the exact same behavior. So I suppose its not to do with database but some configuration or version etc.
I also enabled debugging option in etc conf setting of Gephi.
-J-Dnetbeans.logger.console=true -J-ea
But this is not opening or printing anything. I also tries to find Gephi log file which I cannot. Could not find anything of google. Any idea what may be going on or how to debug/ see log file etc? Appreciate any help
You want to try the following in Gephi
1. Go to Tools - > Plugins - > Updates
2. Select all the plugins listed and click update
I found a way to get around this obstacle.
you can export your data from Neo4j to a CSV file, and then upload the file to Gephi.
hope it gets you what you need.
I just installed Neo4j 2.2 Milestone 1 Release on a Windows 64-bit machine and I am unable to locate the file Neo3jImport.bat.
I want to play around with the feature described here. Until now, I have been playing around with the RNeo4J package. It has helped the learning curve quite a bit, but now that I am goint beyond toy datasets, importing data using the package is painful.
With that said, I can't seem to locate the file/utility that seemingly makes importing larger datasets a breeze. I was expecting to see the file at C:\Program Files\Neo4j Community\bin.
I imagine this is a really basic question, but I am somewhat stumped.
Thanks in advance.
Sorry for the exclusion but the binary installation misses also Neo4jShell and other command line scripts as is is intended for a UI only user.
Please use the ZIP download from neo4j.com/download as Mark suggested.
When i bring an HDF5 file into QGIS that contains raster information, the data visually appear however spatially, they are not projected properly. QGIS does not read the spatial CRS information embedded in the hdf5 file.
Does anyone know what QGIS looks for in terms of syntax and attributes (and where) when it opens an HDF5 file? I'd like to adjust my HDF5 files so that the CRS information reads and QGIS can project the data.
Thank you for any direction

According to the GDAL documentation for the HDF5 driver there is no standard way of doing so.
But something worth trying is to peek at a file which does work for you. Unfortunately i don't have a GDAL driver which can write HDF5 files, but i can create a HDF4 file. If i convert a (georeferenced) Geotiff to HDF4 with GDAL, QGIS reads it correctly, with CRS information etc.
GDAL creates four global attributes, it might be worth trying to create those in your HDF5 file. I'm not sure if all of them are necessary, the 'Signature' doesn't seem crucial. Though it really depends on the implementation of HDF5 in QGIS, it could be completely different compared to HDF4.
i got a customer who wants to migrate from an old Fujitsu COBOL based system to our system, said that, he wants his old data to be kept in the new system, like products,manufacters, etc.I dont have the COBOL source file, i have: .DAT files, .RDD files and .FDD files.
Apparently the .DAT files are in the INDEXED organization, a sample file output bellow:
FDD output:http://textuploader.com/kxdv
RDD output:http://textuploader.com/kxdw
I can't simple read the .DAT file in notepad, i've tried the SiberDataViewer but unsuccesfull, also it gets paid to export the data.
If there's a way, can i write a program to export all these files to csv,dbf,postgres format? If you are still reading, thank you.
I do not know Fujitsu COBOL but as I see it there are a few ways you might be able to get at the data:
0) Have your customer (or someone with a compatible Fujitsu COBOL compiler) write a COBOL program to read the INDEXED file and output a SEQUENTIAL file.
1) Find a Fujitsu COBOL utility to do the same.
2) Find a product that can read the INDEXED file and export it into something you can use. I'm thinking of products like Cyberquery or Crystal Reports, etc. Or, after I saw that the FDD/RDD files were produced by Siber Systems, a quick search helped me find their "Cobol DataViewer" product; use that to output it to a "more common and usable format" ;-)
I could convert it using the Siber DataViewer, but, its full version is paid.
