You're right, it seems to be implem
thats interesting.
that makes me wonder the real use of BlankNode class.

is it still not implemented? or anybody else might be working on it.
Thanks Mattias

Hi guys,
Over at TinkerPop we have developed a ScriptEngine of ScriptEngines called
Mutant [ http://mutant.tinkerpop.com ]. While not particular to graphs, it has
some nice functionality that may be good for the graph database world. For
example, people like to define traversals in Gremlin, but
Currently neo4j-rdf (and inherently neo4j-rdf-sail) doesn't support blank
nodes. You could perhaps make up blank node URIs to represent blank nodes...
and even try to put that into the neo4j-rdf component (or some other
solution) if you feel that you have the time for it!

Hi, everybody,
I work in a lab at University of Western Ontario, with humanists
people. The needs of the humanist research make useless the current
SQL databases because it's hard to change the schemas or build queries
with several JOINs. So, we are developing a system which mixes a
relational dat

thank you for your time,

Do we blank nodes in neo4j-rdf/neo4j-rdf-sail ?
I create a sail following the instructions on the
http://components.neo4j.org/neo4j-rdf-sail/
and tried to load some RDF data in, got the following exception:
java.lang.UnsupportedOperationException: Nodes without URIs (e.g. Blank
Nodes) not support
Kalin (and list),
My lab project for a few weeks now has been an alternative shell to Neo4j.
Coming from a DBA background, I felt that we are lacking tools to do
DBA-work - import/export data, tune indexes, browse the data in an easy way,
and make backups. So that's been the focus for my shell.
As I mentioned in my response to Andreas' original question, "SQL-like"
access (and storage) to/from a graph can be achieved, but requires a
domain-specific layer on top of the graph (but isn't that difficult to
create). We built ours such that we could fairly easily wrap our REST-ful
API in a JDB
Peter,
Those are certainly viable alternatives (need to investigate further), but most
involve learning another language/interface or working at the command line or
within a script.
The ubiquity of SQL access to a database is a big factor when considering
migration. One of my teammates is much b

Let me contribute my 2 cents here.
I have developed a rough demo that shows what my thoughts are for
integration of Neo4j instances in a managed envir
Kalin,
I think the different shell access possibilities are good candidates
for fast integration. You have at least
Neo4j Shell, distributed with Neo4j downloads, see
http://wiki.neo4j.org/content/Getting_Started_with_Neo4j_Server#Enter_the_Shell
JRuby scripts, see http://neo4j.rubyforge.org/ and
Christopher has been doing a POC with this, which seems to have worked
out very well, see
http://blog.fakod.eu/2010/11/29/neo4j-rest-server-gwt-and-jit-part-3/
So, is JIT the best available JavaScript option out there?
