4store is a database storage and query engine that holds RDF data. It has been used by Garlik as their primary RDF platform for three years, and has proved itself to be robust and secure.
+
4store's main strengths are its performance, scalability and stability.
+It does not provide many features over and above RDF storage and SPARQL
+queries, but if your are looking for a scalable, secure, fast and efficient RDF store,
+then 4store should be on your shortlist.
+
License
+
4store is available under the GNU General Public Licence, version 3.
+
Platform
+
It is written in ANSI C99, and designed to run on UNIX-like systems.
+
4store is optimised to run on shared–nothing clusters of up to 32 nodes, linked with gigabit Ethernet. However, it will also work on single machines, if your data requirements are not large.
+
Portability
+
4store is primarily intended to run on Linux platforms, but it is known to work on single Mac OS X machines. It depends on the Avahi multicast DNS library for its clustering support, which is not easily available on Mac OS X.
+
Performance
+
When configured as a cluster, import performances of 120 kT/s are easily achievable. Query times for relatively simple queries are often in the low milliseconds, even over the standard HTTP SPARQL protocol.
+
Security
+
Some of the features commonly found in RDF stores pose security risks
+when deployed inside typical enterprise computing environments. Significant
+effort has gone into ensuring that 4store does not pose a risk by being a
+vector for relay or amplification attacks.

+
Talks and Technical Information
+
Also feel free to contact Steve on if you want him to speak about 4store, Garlik's use of Semantic Web technologies in general, or would like technical information about the design of 4store.
+
Microblog
+
We have feeds on Identi.ca and Twitter. Currently these are used to show commits to the Git repository.
4store was designed by Steve Harris at Garlik from 2006 onwards. The original design brief was a RDF store to hold one billion triples, an ambitious goal at that time. The final system was capable of holding 10+ billion triples, and has been a core part of the Garlik infrastructure ever since. Steve can be contacted at if you have any questions about the design.
+
4store was primarily developed by Steve Harris and Nick Lamb. Nick did the work on the clustering infrastructure, HTTP server and protocol. Steve mainly worked on the query engine and low-level index storage code.
+
4store is the logical successor to 3store, though it shares no code or design in common. For it's time, 3store was considered scalable (around 50MT was achievable on a single server in 2002).
+
Contributing
+
If you would like to contribute work to 4store, please contact the developers on the mailing list for advice, or look at the TODO list.

The Semantic Web is an evolving extension of the World Wide Web in which the semantics of information and services on the web is defined, making it possible for the web to understand and satisfy the requests of people and machines to use the web content. [read more]
+
RDF
+
RDF is a data language used to express triples, expressing the data underlying the Semantic Web. [read more]
+
SPARQL
+
SPARQL is a RDF Query Language, a key Semantic Web technology. 4store uses SPARQL and the SPARQL Protocol for access to all it's internal data. [read more]

There are many other RDF stores available, but 4store is one of the
+few that has been proven in a secure, production enterprise environment. It
+occupies the “Big Dumb Triplestore” space, with few features, but good
+performance, and being very simple to use, once installed.
+
4store was designed to handle loads of 1GT and up, stored on small clusters of generic multi-core 64bit x86 servers, but is also capable of handling smaller datasets running on a single server.
It really depends on how complex the data is, and how fast you want it to be.
+
In Garlik, the largest production system we've run is a cluster of 9 machines, with 8GB of RAM each, holding 15GT in total. At that size performance isn't at it's peak, but it was more than adequate for our application. With more RAM it would have run at full speed.
+
Due to the storage algorithms used there is the possibility of hash collisions are large sizes, the risk becomes significiant as the number of unique resources (c.f. 4s-size) approaches 10 billion, this is typically around the 50-70GT mark.
Though still very capable, 4store is no longer Garlik's primary RDF store. It still works well in scales up to around 10 billion triples, and has a sophisitacted query optimiser by SPARQL standards. We would like to make RDF deployments in large organisations and coporate environments easier, so to that end we decided to release 4store under the GPL licence.
+
The replacement for 4store is called 5store, it's not available under a open source licence, but we are willing to commercially licence it to 3rd parties.
It's easiest to install on Linux systems, we recommend CentOS 5 or
+newer, RedHat Enterprise 5+, or Fedora Core. But it's known to work fine on
+Ubuntu, Debian and Gentoo distributions. We only have experience of running it on RedHat derived
+systems though.
+
Other than things provided by the OS (Ubuntu has Raptor and Rasqal as debs), you'll need Dave Beckett's Raptor and Rasqal libraries.
This indicates that you are trying to use the 32-bit glib2 headers to compile 4store against 64-bit libraries. Check that you have the 64-bit development package for glib2 installed, and that your PKG_CONFIG_PATH is set appropriately.

4store, an efficient, scalable and stable RDF database
+
4store was designed by Steve Harris and developed at Garlik to underpin their Semantic Web applications. It has been providing the base platform for around 3 years. At times holding and running queries over databases of 15GT, supporting a Web application used by thousands of people.
We'd really appreciate feedback on 4store, and there are a variety of ways to contact us.

Introduction
+
In this tutorial we plan to cover:
+
+
Install and setup of 4store
+
Cluster configuration
+
Performance tips and tricks
+
and maybe
+
Diagnostics
+
+
Please interrupt if you have questions
+
We'll try and cover everything, but might have to skip a few things if we run out of time.
+
+
+
+
Setup - Requirements
+
+
64-bit for production
+
4store uses memory mapping, limited address space
+
+
but 10s of millions of triples without
+
Most tested on x86-64 with CentOS 5
+
RAM > CPU > disk
+
but remember to allow for raw RDF data
+
./configure
+
checks source code dependencies, not autoconf
+
+
+
+
+
Setup - installation
+
+
source install
+
(Hopefully binary packages are similar but easier)
+
/usr/local/lib(64) + ldconfig
+
/var/lib/4store
+
+
Use a separate 4store user ?
+
Not essential, avoids permissions problems, alternative is chmod 777
+
+
4s-httpd / 4s-query / 4s-import doesn't need access
+
+
+
+
+
Setup - backend settings
+
4s-backend-setup ...
+
+
4s-backend-setup
+
--node 0
+
--cluster 1
+
--segments 16
+
--mirror
+
+
Security
+
+
4s-backend-setup --password sesame
+
Shared secret
+
Link is not encrypted
+
+
+
+
+
+
+
Clusters - Principles
+
+
Fast local network
+
Low-latency, 100Mbit ok, Gbit better
+
Same LAN for DNS-SD
+
Could go beyond LAN, but untested, performance would suffer on slow links
+
High-bandwidth operations are unicast
+
So you don't need a smart (expensive) switch that groks multicast
+
+
+
+
+
Clusters - Diagram
+
+
+
+
+
+
Clusters - Tools
+
+
SSH based - /etc/4s-cluster
+
operations initiated from 'master'
+
Public key infrastructure
+
+
manual (with Agent forwarding)
+
shosts
+
pre-seed keys to master or use DNSSEC
+
+
+
+
+
+
Clusters - Tools
+
+
4s-cluster-create
+
4s-cluster-start
+
4s-cluster-stop
+
4s-cluster-destroy
+
+
+
+
4s-cluster-info
+
4s-cluster-copy (must be quiescent)
+
+
+
+
+
Clusters - Practice
+
+
+
Many identical installs so e.g. Kickstart
+
Building a reliable script is tricky, but once it works it is pretty reliable
+
Try to avoid doing unattended installs until you're comfortable
+
+
+
+
Decisions
+
+
DHCP? LLv4? (or IPv6)
+
DNS? mDNS? (want nss-mdns)
+
NFS? rsync? package updates
+
NFS binary updating problem
+
NIS?
+
Maybe, if you already use it, but 4store user set up by Kickstart may be enough
+
+
+
+
+
Clusters - Demo
+
+
LLv4 + mDNS
+
Same user on every machine - or something?
+
+
Don't try this at home !
+
Protocol version compatibility, debug nightmare etc.
+
+
+
+
+
+
+
+
+
+
Filesystem Layout
+
+
4store places its data in : /var/lib/4store/
+
A directory is created for example KB present : /var/lib/4store/[KBNAME]/
There are a number of different indexes in the 4store segment directory
+
+
rhash*, ptrees, an mhash, and a tbchain
+
+
+
+
+
+

Projects using 4store
+
4store has only been available outside of Garlik for a short while, but it is already used in a handful of projects. The high-level of standardisation between SPARQL-compliant databases makes migrating existing pure SPARQL apps to 4store simple.
+
If you would like your project included on this page, please contact us with a description of the project and how you're using 4store. Even if you don't want your project listed here, we're still keen to hear how people have been applying the technology.
Garlik's primary product, used by hundreds of thousands of users. DataPatrol helps people take control of their personal information and protect themselves against identity theft and financial fraud. DataPatrol was originally run from 4store, though it's now been migrated to 5store. [link]
Live Social Semantics is a social experiment, where the Semantic Web, the Social Web, and the Physical World will come together to create a rich integrated network of information. Acquiring and integrating these heterogeneous, but overlapping, data sources enables a range of novel services to conference attendees.
MBI is a project with a clear objective of making a significant performance improvement in UK business to business (B2B) marketing activities in the 5-7 year time frame. The project plans to aggregate a broad range of business information, providing unparallelled insight into UK business activity and develop rich semantic search and navigation tools to allow any business to 'place their sales proposition in front of a prospective buyer' confident of the fact that the recipient has a propensity to buy. [link]
“What would you build with public data?”. OpenPSI is a new form of community provisioned information service designed to stimulate interaction between:
+
+
The research community
+
Public sector information publishers
+
The new information intermediaries (mashup creators)
+
+ OpenPSI currently holds SICCODE 2003, the Ordnance Survey Administrative Geography and the London, Belfast and Edinburgh Gazettes as RDF inside 4store. [link]
eRDF was the runner up in the Billion Triples Challenge for 2009. It's built on a 4store instance runing on Amazon Web Services, they made the 4store AMI image used to build the entry pulbic. [link]
