Metalyzer is a extension to the IF-MAP visualization suite VisITMeta (works with version 0.2.0 or newer).
It extends the VisITMeta dataservice to perform statistical methods and semantic(-like) queries on MAP graphs and visualize the results within a GUI. With the use of VisITMeta’s history of MAP data, time-variant analysis can be done.
The software was developed during a students project at Hochschule Hannover.
Prerequisites and pre-setup
In order to build Metalyzer with Maven you need to install Maven 3 manually or via the package manager of your operating system.
Installation of R engine
The dataservice module of Metalyer uses the R project for some of its statistical analysis. Prior to building Metalyzer you must install a R runtime on your system and set (at-least) the following environmental variables
R_HOME should be something like
export R_HOME=/usr/lib/R export CLASSPATH=.:/usr/lib/R/site-library/rJava/jri
Apple Mac OSX
export R_HOME=/Library/Frameworks/R.framework/Resources export CLASSPATH=.:/Library/Frameworks/R.framework/Resources/library/rJava/jri
This section describes, how to build Metalyer from scratch.
Install VisITMeta as a prerequisite
In order to build Metalyzer, you need to install VisITMeta, as some of its code from visitmeta-common is used in Metalyzer.
To do so, load VisITMeta from our Github page and build it via
$ mvn install instead of
$ mvn package.
After that, the libraries of VisITMeta should reside in your local Maven repository (~/.m2 in most cases).
Now you can build Metalyzer via
$ mvn package in the root directory of the Metalyzer project (the directory
README file). Maven should download all further needed dependencies for you.
After a successful build you there are two important artifacts:
metalyzer-dataservice-module-distribution: Copy the file
target/metalyzer-dataservice-module-distribution-<version>-bundle.zipto a new folder called
dataservice-moduleswithin the VisITMeta application root directory and unzip it there.
metalyzer-visualization-distribution: Unzip the file
target/metalyzer-visualization-distribution-<version>-bundle.zipto a arbitrary place.
Change your working directory to the root directory of the VisITMeta project.
Start the VisITMeta dataservice via
$ sh start-dataservice.sh. This will try to load the Metalyzer dataservice module. If successfully loaded, you should see somethink like
[main] INFO de.hshannover.f4.trust.metalyzer.api.MetalyzerModule - Metalyzer dataservice module v0.1.0 started successfullyin the log output.
Start the Metalyzer GUI via
$ sh start-metalyzer.shfrom within the directory containing the
Publish some data. Within the
scriptsdirectory of VisITMeta, you will find some Shell scripts that work with our ifmapcli-tools and will publish and delete some metadata, so that you can test the statistical and semantical analysis functionality of Metalyzer.
