Metalyzer and VisITMeta 0.2.0 released

alternate text

With Metalyzer we introduce a software, that allows to analyse IF-MAP data for statistic and semantic features.

Metalyzer consists of two separate modules:

  1. a module that can be loaded by the dataservice application of VisITMeta, that performs the analysis on MAP data and provides REST-like access to the results

  2. a visualization client that presents these results via tables, charts and other diagrams.

Some of the analysis that can be done with Metalyzer include the absolute and relative frequencies of different identifiers and metadata or an overview of associated IP addresses and MAC addresses, found by following a given path in the IF-MAP graph data.

The statistic analysis is partly done by using the R framework, whereas the visualization via charts and diagrams uses the JFreechart library.

Metalyzer was developed by a group of 9 students during their bachelor studies within two terms at the Hochschule Hannover.

Please find the sourcecode and instructions on how to build Metalyzer and include it in a VisITMeta runtime environment in the projects Github repository.

In combination with the release of Metalyzer in its first version we also release VisITMeta in version 0.2.0. The main feature of this version is the added support for external modules - like Metalyzer - , to allow arbitrary processing on the stored MAP data.

We also fixed a bug that happened when the delta is calculated after a single value metadata was updated, and added the possibility to select and unselect single nodes in the GUI application.

The sourcecode of VisITMeta is also available at Github on the projects repository page.
