One is to automate the whole of data collection. That's a long-term goal, and not needed for the MSFT project. The MSFT project is to put some part of our world into the Azure cloud. What we chose to do is build a small dashboard that displays status of data loading for one customer (a customer-specific view) or all customers (a G4 view.) For that we just need to pick one customer and make sure their ETL packages log details as they go. From there we push that data into a cloud db and display some views over it.

Can you please review the ETL packages to let me know if the ones for each file run the same stored procedures over and over again? While the sprocs being run do not take much time, we should of course clean it up if needed. If so, we must move those stored procedures into a new SSIS package and remove them from all of the file-loading packages for each CAM retailer and manufacturer. Also, I know that some of the files will be loaded manually to get a head start, especially when files are late or processing is going slowly. Do you still do that for NOM? We need to account for whether Bill can wait for the files to accumulate before running them, or if we should have a job that loads them as soon as they are downloaded. Lastly, what tests do you run after the ASDA and Morrisons files are downloaded from their web sites to ensure the files are not bad ones?

NOM ASDA Package Processing could kick off all jobs indented below it once all the ASDA files are received.

Re: [Neo4j] py2neo - GEOFF enhancements
Having played around with some ASCII art (quite good fun actually!) it is
starting to feel more natural to re-order the index entries, so that the
key:value part is both consistent with existing syntax and adjacent to the
index reference. I have ended up with:
# ADD ENTRY:
# ensure node bert has an entry in index Scientists
# where name = Einstein
(bert)=|Scientists| {name: Einstein}
Here I have altered the - arrow to = - these arrows have a different
meaning to those used for relationships so it is fair to differentiate them
visually. The reversal of order of the components not only feels more
natural but also allows us to also produce things like:
# REMOVE ENTRY:
# ensure node bert does not have an entry in index Scientists
# where tidy_hair = true
(bert)!=|Scientists| {tidy_hair: true}
# LOOKUP ENTRY:
# define node bert as the (first?) entry in index Scientists
# where name = Einstein
(bert):=|Scientists| {name: Einstein}
On a side note, I've also been pondering some built-in hook syntax which is
slightly borrowed from XPath:
# Built-in hook for reference node:
{/}-[:THINGS]-(foo)
# Built-in hooks for sub-reference nodes:
{/THINGS}-[:THING]-(thing)
WDYT?

Hi Michael
GEOFF was originally conceived as a graph serialisation format and, as
such, was intended to represent a snapshot of entities at a particular
point in time instead of, as you are discussing, a programmatic set of
actions (add, replace, remove, etc). That said, these ideas are still
worth
exploring...
First off, since hooks are the variables of GEOFF, it would seem
consistent to use those for assigning the return values of index lookups
and queries. Something like the following could be used to perform an
index
query, assign the result to a hook and use that hook to build a
relationship:
{foo} := |index| @ {key: value}
{foo}-[:KNOWS]-(bar)
Actually, since the index query may result in multiple returned entities,
we might want to limit to the first item returned:
{foo} := |index| @ {key:value}
{foo.1}-[:KNOWS]-(bar)
Using the other operators for adding, removing and replacing index
entries,
this would make...
# add node bert to index at foo:bar
|index| @ {foo: bar} += (bert)
# remove node bert from index at foo:bar
|index| @ {foo: bar} -= (bert)
# replace node with bert in index at foo:bar
|index| @ {foo: bar} := (bert)
So essentially, we would be looking at at least the following
requirements:
1. Allow hooks to hold multiple entities instead of just a single
entity
2. Allow assignment to hooks
3. Implement an @ operator to allow inline index queries
4. Implement assignment, addition and removal operators to indexes
These ideas would turn GEOFF into much more of a programming language
than
a notation for serialisation: a big change and one which would
potentially
require another significant rewrite. I'm not against doing this but I'm
wondering if this is a valuable direction to go in and whether, if we
were
to do this, it would be better to start from first principles instead.
Would this fill a gap that none of the other current options can?

Are you thinking of something like {People:name=bert}? If so, this is
quite a distance from where we are currently since every token can only
refer to a single entity, whereas an index lookup could return multiple
results.

Doesn't handle iterables (yet) but should be quite easy to add in. What
purpose did you have behind longs?
I've just committed a few new methods allowing the Neo4jNamespace
returned
from a loadIntoNeo4j call to be used to retrieve new entities by name
(or a
map of such). The new methods are:
public Node getPreexistingNode(String name)
public MapString, Node getPreexistingNodes(String... names)
public Node getNewlyCreatedNode(String name)
public MapString, Node getNewlyCreatedNodes(String... names)
public Relationship getPreexistingRelationship(String name)
public MapString, Relationship getPreexistingRelationships(String...

public Relationship getNewlyCreatedRelationship(String name)
public MapString, Relationship getNewlyCreatedRelationships(String...

One of the tests in GraphDescriptionTest illustrates simple usage,
thus:
Neo4jNamespace ns = GEOFFLoader.loadIntoNeo4j(reader, db, hooks);
Node nodeFoo = ns.getNewlyCreatedNode(foo);
Node nodeBar = ns.getNewlyCreatedNode(bar);
Hope this helps - I'll have a play with iterables next.

[Neo4j] Batch URIs
Following on from the relative URI work that Jim is looking at, I was wondering if there was any way that the entity URIs used for RESTful batch requests could be made more discoverable or elegantly derivable? Currently the only way I'm aware of to calculate a relative node URI, for example, is to hack around parts of the full URI: self._relative_uri = .join(self._uri.partition(/node)[1:]) Basically here I'm looking for the substring /node within the full URI and taking everything from that point onwards as the relative part which I use to inject into a batch payload. This is obviously somewhat dependent on this hardcoded part never changing and doesn't feel particularly like the most elegant way to achieve this. Thoughts welcomed! *Nigel Small* Phone: +44 7814 638 246 Blog: http://nigelsmall.name/ GTalk: ni...@nigelsmall.name MSN: nasm...@live.co.uk Skype: technige Twitter: @technige https://twitter.com/#%21/technige LinkedIn: http://uk.linkedin.com/in/nigelsmall ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
Re: [Neo4j] py2neo - GEOFF enhancements
Hi Michael
Doesn't handle iterables (yet) but should be quite easy to add in. What
purpose did you have behind longs?
I've just committed a few new methods allowing the Neo4jNamespace returned
from a loadIntoNeo4j call to be used to retrieve new entities by name (or a
map of such). The new methods are:
public Node getPreexistingNode(String name)
public MapString, Node getPreexistingNodes(String... names)
public Node getNewlyCreatedNode(String name)
public MapString, Node getNewlyCreatedNodes(String... names)
public Relationship getPreexistingRelationship(String name)
public MapString, Relationship getPreexistingRelationships(String...
names)
public Relationship getNewlyCreatedRelationship(String name)
public MapString, Relationship getNewlyCreatedRelationships(String...
names)
One of the tests in GraphDescriptionTest illustrates simple usage, thus:
Neo4jNamespace ns = GEOFFLoader.loadIntoNeo4j(reader, db, hooks);
Node nodeFoo = ns.getNewlyCreatedNode(foo);
Node nodeBar = ns.getNewlyCreatedNode(bar);
Hope this helps - I'll have a play with iterables next.
Cheers
Nige

Re: [Neo4j] py2neo - GEOFF enhancements
Hi Michael
Probably better to just return the full map and let the client code deal
with it ? (If it isn't interested it would either just ignore the return
result or discard it quickly).
Done. Now works as:
MapString,PropertyContainer entities = GEOFFLoader.loadIntoNeo4j(reader,
db, hooks);
Node nodeFoo = (Node) entities.get((foo));
Node nodeBar = (Node) entities.get((bar));
Intention behind longs, is when I get them from an external source then
they can be used to be look up nodes during import.
This can be done but not sure it's the right place... I'm cautious about
using IDs directly as they aren't very portable. Also, it's not intuitive
whether an ID is for a node or relationship. Would like to get a few votes
on this - I'm happy to be outvoted if the consensus is to do it!
Also can hooks be used for index lookups? (Just asking)
Are you thinking of something like {People:name=bert}? If so, this is
quite a distance from where we are currently since every token can only
refer to a single entity, whereas an index lookup could return multiple
results.

Changing the REST API to only use relative URIs would have a significant effect on py2neo. Is this likely to happen?

Re: [Neo4j] py2neo 0.982
Hi Krzysztof Yes, certainly looks like it's a bug, however I'm convinced this has changed from the original REST docs on which I based this code. Can't find a copy though and since your fix looks to apply to both 1.4 and 1.5 then consider it merged!

I think i found a bug that prevents from using javascript filters when traversing over rest: http://py2neo.org/docs/api/py2neo.neo4j-pysrc.html#TraversalDescription.filter Instead of body, key is named name. Since you're on vacation i've taken justice of sending you a pull request over on github with proposed fix.

Re: [Neo4j] py2neo 0.982
So that we can support both, I've made some further changes to the TraversalDescription class. I have replaced prune and filter with: builtin_prune_evaluator(self, name) prune_evaluator(self, language, body) builtin_return_filter(self, name) return_filter(self, language, body) This does break some backward compatibility with the methods but does provide more clarity than the original. I'm also aware that some of this has been deprecated within the core API; however, since this does not yet appear to be reflected within the REST API, this is probably the best option for now. WRT your suggestion for the Node class: I'm happy to consider it but will need to read up more on the JPype bindings as I'm not familiar with them. Could you submit an issue, preferably containing a link to docs describing the interface you describe, and I'll have a proper look.

I also have one issue with Node class, i really like the way original JPype bindings work - i.e. i can use node.loves(cake, how='deeply') to define a relationship, and also properties are easily accessible like class members. This could be easily implemented with some dose of __getattr__ magic, and pretty easily too. Question is wether such change in API would be accepted? Also, automatic binding of properties to node instances would be awesome too. Please let me know if you are interested, i'd gladly help. ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
Re: [Neo4j] py2neo 0.982
Hi Krzysztof Having looked at your Pull Request, I can see that your syntax certainly provides a easy and readable way to create relationships to nodes. However, I have a couple of reservations: 1. This essentially uses a get operation to carry out a write behind the scenes. I would generally try to avoid something which is intuitively read-only from having side-effects such as this. 2. Using the __getattr__ method in this way precludes using it to access Node properties which is, arguably, the more obvious use (even though __getitem__ is already used here). I don't entirely dislike the idea but given this is really just syntactic sugar, I'd like to hear other's opinions on this. The new prune/filter methods aren't restricted purely to JavaScript: they now simply have built-in and custom variants with clearer naming. My philosophy is generally to swing towards longer/clearer and more descriptive names as opposed to trying to save a few keystrokes and making one function do multiple things.

I will also submit my proposed index syntax changes. I'm no good at git, so i may or may not screw this up. As far as changes you wrote about, i think we should move it to one method, and rely on arguments supplied by user to know which prune/filter to use. Also, are there any other language options besides javascript for evaluators?

Re: [Neo4j] py2neo 0.982
Hi Michael
Completely agree on named parameters - I'd like to support both named and
positional - both have advantages.
I also like the idea of the {foo} syntax as consistency with Cypher is what
I have tried to provide all along here. I actually don't believe that it
will be confusing with JSON (even with the composite descriptor syntax) but
this notation is unfortunately already used by the index entry syntax:
{my_index}-(my_node)
Having said that, this clash doesn't have to give us a major problem. We
could deprecate the existing index entry syntax (possibly maintaining
backward compatibility for a while with a bit of regex jiggery-pokery) and
replace it with something new, such as:
my_index-(my_node)
or
|my_index|-(my_node)
Back to parameters. There's an amazing amount of strength in the concept of
multiple entities specified by a single token so agree that we should look
further into that. Behind the scenes, it should be simple enough to add
multiple entries when one of these is encountered, by iterating through the
items. Even more Interesting with something like:
{parents}-[:PARENT_OF]-{children}
which could break down to:
(father)-[:PARENT_OF]-(child1)
(father)-[:PARENT_OF]-(child2)
(mother)-[:PARENT_OF]-(child1)
(mother)-[:PARENT_OF]-(child2)
The comma syntax, again, looks very useful. Would this lead to us wanting
some form of pattern matching as well?

So one could take the output of a traversal or cypher query (with aliases

Allowing us to do mass-updates or structural connections in one go.

Imagine we are trying to inject a simple graph, such as the following:

Currently, this would be loaded into graphspace without any attachment to
existing structures; a join would have to be made *after* the load.
If we instead consider parameterising the load, e.g.
loadIntoNeo4j(reader,
graphDB, someNode, otherNode, ...), we can reference the supplied nodes
from within the GEOFF data. I think that ($n) notation would be quite
useful here as it is already familiar from bash etc. This might therefore
turn the above subgraph into:

(dad) {name:Nigel}
(son1) {name:Joshua}
(son2) {name:Stephen}
(dad)-[:FATHER_OF]-(son1)
(dad)-[:FATHER_OF]-(son2)
($1)-[:FAMILY]-(dad)
...such that ($1) refers to the first supplied parameter, ($2) would be
the
second and so on. ($0) could possibly refer to the reference node of the
destination graph, by definition.
Hope this makes sense! What do you reckon?

Re: [Neo4j] py2neo 0.982
Yep, absolutely. Probably won't get a lot done this week though as I'm on
holiday in México at the moment and don't have much in the way of dev kit,
plus the wireless is a little flaky. That said, I'll start poking it if I
get the time and see how far I get.
So in summary, assuming we are going to allow passing both nodes and
relationships as parameters, the bits I'll look at adding will be as
follows:
- positional/named parameter capabilities for the load method (each
parameter can designate a Node or Relationship)
- support for embedding parameterised Nodes within GEOFF relationship
descriptors:
(node1)-[rname:rtype]-(node2)
(node1)-[rname:rtype]-{param}
{param}-[rname:rtype]-{param}
{param}-[rname:rtype]-(node2)
(May throw WrongParameterTypeException if start or end node param is
actually a Relationship)
- new syntax allowing properties to be assigned to parameterised entities
(Nodes or Relationships):
{param} {key:value, key:value, ...}
- alteration to existing index entry syntax to move away from braces
(although possibly maintaining backward compatibility):
|index|-(node) {key:value}
|index|-[rel] {key:value}
- new syntax allowing index entries for parameterised entities:
|index|-{param} {key:value}
Agreed?

Are you looking for info on associated projects like py2neo or direct contributions to the main code base? On a side note, I've been getting quite a few hits to my blog post on pagination in Neo4j. The bits I wrote for that are all Python/py2neo again but that or something similar might be worth including somewhere on the Neo site as it appears to be a reasonably sought-after topic.

Re: [Neo4j] py2neo 0.982
Hi Peter
Imagine we are trying to inject a simple graph, such as the following:
(dad) {name:Nigel}
(son1) {name:Joshua}
(son2) {name:Stephen}
(dad)-[:FATHER_OF]-(son1)
(dad)-[:FATHER_OF]-(son2)
Currently, this would be loaded into graphspace without any attachment to
existing structures; a join would have to be made *after* the load.
If we instead consider parameterising the load, e.g. loadIntoNeo4j(reader,
graphDB, someNode, otherNode, ...), we can reference the supplied nodes
from within the GEOFF data. I think that ($n) notation would be quite
useful here as it is already familiar from bash etc. This might therefore
turn the above subgraph into:
*
(dad) {name:Nigel}
(son1) {name:Joshua}
(son2) {name:Stephen}
(dad)-[:FATHER_OF]-(son1)
(dad)-[:FATHER_OF]-(son2)
($1)-[:FAMILY]-(dad)
...such that ($1) refers to the first supplied parameter, ($2) would be the
second and so on. ($0) could possibly refer to the reference node of the
destination graph, by definition.
Hope this makes sense! What do you reckon?

From what I can tell, the POST payload is pretty quick to create but the whole process slows down considerably on submission.

Re: [Neo4j] Cypher-Pickle?
newbies may find it helpful to start with something they already know. One problem with this is that it could invoke a tendency to try to map relational concepts onto a graph db. The two types of database are fundamentally different at the lowest level and if one starts off by thinking where do I put my 'tables'? they are only heading down the wrong path. I mentioned a while back that I felt designing a graph database is more akin to OO design that to relational design. Maybe we should stop using the word database?? :-P * * *Nigel Small* Phone: +44 7814 638 246 Blog: http://nigelsmall.name/ GTalk: ni...@nigelsmall.name MSN: nasm...@live.co.uk Skype: technige Twitter: @technige https://twitter.com/#!/technige LinkedIn: http://uk.linkedin.com/in/nigelsmall On 5 November 2011 14:03, Axel Morgner a...@morgner.de wrote: People already familiar with graphs seem to love the original Cypher syntax while newbies may find it helpful to start with something they already know.

Also agree. Using several illustrative symbols instead of one cryptic one adds a considerable amount of readability as the expense of negligible overhead.

Hi all,
following Nigels great work, I created a separate GEOFF plugin for the
Neo4j Server, https://github.com/neo4j/geoff-plugin (depending on
https://github.com/nigelsmall/neo4j-geoff-plugin, hoping to get both
building on CI soon) . It lets you submit GEOFF in JSON like
POST http://localhost:7474/db/data/ext/GeoffPlugin/graphdb/insert
Accept: application/json
Content-Type: application/json
{geoff:{(Joe):{name:Joe}}}
Which results in the creation of a node with name=Joe. For more
cool examples, see http://py2neo.org/geoff/
Thanks a lot Nigel for pushing this!
Now, I am not sure how to handle the ordering of things, like adding
indexes needs to be done after creating nodes, but it's a good start
:)

New output format is straightforward, could you add a ticket to the project? Cheers Nige On 31 Oct 2011 08:41, Michael Hunger michael.hun...@neotechnology.com wrote: Nigel, cool stuff. What is the easiest way to install py2neo currently? Could you add a simple tabular output as well (like in the webadmin-cypher-console) ?

Putting together more docs this week so will update soon.
