Preview Release for Neo4j 3.1.0-M10 with User Defined Functions

We already converted about 50 procedures into functions from the following areas:

package	# of functions	example function
date & time conversion	3	apoc.date.parse("time",["unit"],["format"])
number conversion	3	apoc.number.parse("number",["format"])
general type conversion	8	apoc.convert.toMap(value)
type information and checking	4	apoc.meta.type(value)
collection and map functions	25	apoc.map.fromList(["k1",v1,"k2",v2,"k3",v3])
JSON conversion	4	apoc.convert.toJson(value)
string functions	7	apoc.text.join(["s1","s2","s3"],"delim")
hash functions	2	apoc.util.md5(value)

We also started to add default values for parameters and deprecate procedures that required alternative names because of a wider parameter set.

We also moved the Description annotation from APOC's own to the one now provided within Neo4j, so you'll see the descriptions for all functions and procedures in dbms.procedures().

3.0.4.1 Release of Awesome Procedures On Cypher (APOC)

*NB: This release requires at least Neo4j 3.0.4. *

A ton of new procedures has been added, in total we do now have a collection of way more than 200 procedures.

Thanks to everyone who made that happen.

1.1.0 Release of Awesome Procedures On Cypher (APOC)

More than 100 new functions since the last APOC release. Especially around data integration, there are now new means to exchange data with ElasticSearch, MongoDB, Cassandra and Gephi. There were also a lot of new convenience functions added in all sections.

Thanks a lot to all contributors and users who reported back with feedback, suggestions and pull requests.

There will be an ongoing blog series on https://neo4j.com/blog about the different aspects covered by APOCs.

If you like the library please tell your friends and colleagues.

First release of APOC

Over the last few weeks since the release of Neo4j 3.0.0 on April 26, APOC gathered a lot of new functionality including

• free text search
• first graph-algos like page-rank, centrality, allSimplePaths, label-propagation and clique finding (WIP)
• bit-operations
• geocode
• warm-up
• more utility, time, map, and string functions

There are new docs in development at http://neo4j-contrib.github.io/neo4j-apoc-procedures/

That's why I felt a first release was due. And because I wanted to get it into your hands.

ENJOY!
And make sure to report feedback and ideas as GitHub Issues

First APOC release

In this first release APOC already comes loaded with lots of useful procedures for Neo4j 3.0-RC1

Please follow the instructions in the readme for usage tips. You can also use CALL apoc.help('name') for a short description in the browser

Grab the binary JAR, drop it in the $NEO4J_HOME/plugins folder and restart the server. Then CALL dbms.procedures should list them all.
