Rdf sesame installation

We suggest that you use version 4 or 5 of Tomcat, as its configuration is much easier than that of older Tomcat versions i. Java 2 SDK's are available for most mainstream platforms.

Install Tomcat. Please see the Tomcat documentation for more information on how to get it up and running. Extract the sesame. You can also use a program like WinZip or unzip to extract the archive.

We will refer to the directory where you have extracted the sesame. NOTE: only do this for a fresh install of Sesame, if you are upgrading you will already have a config file, and copying the example over it will destroy your existing configuration.

The example file contains some repository entries for different Sails and databases, and one user account. The file may require some modifications in order to work on your machine. Please check out Server administration if you want to learn how to do this.

Re start your Tomcat server and Sesame should now be up and running. Testing Your Installation. Installation under Tomcat 3. Perform the steps described in Installation under Tomcat 4 or 5. As one example of this, Literal. As a consequence, if you previously had code that retrieved the language tag like this:. If you were still using this storage backend as part of your project, you will need to switch to a different database type before upgrading or look into third-party implementations that may still support those databases.

Since Sesame 2, we have cleaned up interfaces, renamed methods and classes, and just generally streamlined a lot of stuff. However, they have been marked deprecated.

This means that we intend to drop support for these older names in future RDF4J releases. In every case, however, we have extensively documented what you should do in the API Javadoc: each deprecated method or class points to the new alternative that you should be using.

Upgrade at your leisure, just remember: better sooner than later. Here, we outline some of these improvements in more detail. All exceptions thrown by RDF4J are unchecked: they all inherit from java. This means that you as a developer you are now longer forced to catch or throw any exceptions that inherit from org. Of course, you still can catch these exceptions if you want, but it means that in cases where you as a programmer are certain that an exception would never occur in practice, you can just ignore the exception, instead of having to write verbose try-catch-finally blocks everywhere.

In other words: we are shifting the responsibility to you as a programmer to take care you write robust code. Be assured that all exceptions that can be thrown will still be properly documented in the Javadoc. For example, instead of:. This enables the parsing of much larger files without being concerned about numeric overflow in tracking.

An alternative to picking libraries by hand is to use Maven. Apache Maven is a software management tool that helps you by offering things like library version management and dependency management which is very useful because it means that once you decide you need a particular Sesame library, Maven automatically downloads all the libraries that your library of choice requires in turn , and giving you a handy-dandy build environment. If you are familiar with Maven, here are a few pointers to help set up your maven project.

To configure your project to use the correct repository, add the following to your project's pom. The groupId for all Sesame core artifacts is org. To include a maven dependency in your project that automatically gets you the entire Sesame core framework, use artifactId sesame-runtime :.

For many projects you will not need the entire Sesame framework, however, and you can fine-tune your dependencies so that you don't include more than you need. Here are some typical scenarios and the dependencies that go with it. If you require functionality for quick in-memory storage and querying of RDF, you will need to include dependencies on the SAIL repository module artifactId sesame-repository-sail and the in-memory storage backend module artifactId sesame-sail-memory :.

A straightforward variation on this scenario is of course if you decide you need a more scalable persistent storage instead of or alongside simple in-memory storage. In this case, you can include the native store:.

The Sesame parser toolkit is called Rio, and it is split in several modules: one for its main API sesame-rio-api , and one for each specific syntax format. If you require functionality to parse or write an RDF file, you will need to include a dependency on any of the parsers for that you will want to use.

Before you begin using any of the Sesame libraries, one important configuration step needs to be taken: the initialization and configuration of a logging framework. SLF4J allows you, as a user of the Sesame framework, to plug in your own favorite logging implementation at deployment time.
