【Sesame】Server Installation 芝麻数据库服务器安装搭建

Sesame is a de-facto standard framework forprocessing RDF data. This includes parsing, storing, inferencing and querying of/over such data. It offers an easy-to-use API that can be connected to all leading RDF storage solutions.

Sesame has been designed with flexibility in mind. It can be deployed on top of a variety of storage systems (relational databases, in-memory, filesystems, keyword indexers, etc.), and offers a large scala of tools to developers to leverage the power of RDF and related standards. Sesame fully supports the SPARQL query language for expressive querying and offers transpararent access to remote RDF repositories using the exact same API as for local access. Finally, Sesame supports all main stream RDF file formats, including RDF/XML, Turtle, N-Triples, TriG and TriX.

This article is a note of the installation of sesame server. there is some problems in official user documentation. I'll show you what is it and how to fix it.

OpenRDF组织的Sesame软件是一款开源图数据库软件，用来存储triple及实现上层查询接口，提供各种底层triple store的支持。

这边总结一下sesame 2.2 与tomcat 7结合实现服务器端图数据库。官方文档有一些错误，导致无法运行（也许是打开姿势不对？= =！）。总之这边提供了一种解决方案。英文不难，下面看看就会了。

Tomcat installation

some problems:

========================================================================================

The startup.sh output:

rk@rk-pc:~/tomcat/bin$ ./startup.sh
Using CATALINA_BASE: /home/rk/tomcat
Using CATALINA_HOME: /home/rk/tomcat
Using CATALINA_TMPDIR: /home/rk/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /home/rk/tomcat/bin/bootstrap.jar:/home/rk/tomcat/bin/tomcat-juli.jar

 

1. Install Tomcat. This usually consists of downloading the binary Tomcat distribution from http://jakarta.apache.org/tomcat and installing it in an appropriate location on your disk (we will refer to this location as [TOMCAT_DIR] here). Please see the Tomcat documentation for more information on how to get it up and running.
2. Go to the web applications directory ([TOMCAT_DIR]/webapps/ by default) and create a directory 'sesame' there.
Extract the sesame.war file (which can be found in the lib directory of the binary Sesame distribution) to the newly created 'sesame' directory. You can do this on the command line by changing directories to the new 'sesame' directory and executing the command jar -xf [PATH/TO/]sesame.war. 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.war file as [SESAME_DIR] in the rest of this document.[This has some problems. Besides above you should copy openrdf-sesame.war to TOMCAT_PATH/webapp. And you dont need to do the step 4 because it does not have the specific file named system.conf.example] 
3. In case you are planning to use a database with Sesame, copy the appropriate JDBC-driver file(s) to the directory [SESAME_DIR]/WEB-INF/lib/.
4. Copy the file [SESAME_DIR]/WEB-INF/system.conf.example to [SESAME_DIR]/WEB-INF/system.conf. 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.
5. (Re)start your Tomcat server and Sesame should now be up and running. You can access the Sesame web interface at http://[MACHINE_NAME]:8080/sesame.     [Use TOMCAT_PATH/bin ---->shutdown.sh & startup.sh]

============================================================

Finally, you can type http://localhost:8080/openrdf-workbench to run it.
