Open Source Data Management Systems

Egonet is a program for the collection and analysis of egocentric network data. It helps you create the questionnaire, collect data, and provide general global network measures and data matrixes that can be used for further analysis by other software. Source code is hosted at http://github.com/egonet/egonet.

Visit our new site: http://socnetv.org Social Network Visualizer (SocNetV) is a social network analysis and visualization application. You can draw a social network (graph/digraph) or load an existing one (GraphML, UCINET, Pajek, etc), compute cohesion, centrality, community and structural equivalence metrics and apply various layout algorithms based on actor centrality or prestige scores (i.e. Eigenvector, Betweenness) or on dynamic models (i.e. Kamada-Kawai spring-embedder)

JUNG provides a common and extendible language for the modeling, analysis, and visualization of data that can be represented as a graph or network. New version now available on GitHub: https://github.com/jrtom/jung/releases/tag/jung-2.1

On The Mark is a video and image scoring system that allows one to mark any number of events and durations through a simple, easy-to-use graphical interface.

@rbre uses X3D to let people create, visualize, browse and share genealogical data, by using 2D individual icons assembled in 3D family trees. @rbre will include P2P functions for sharing.

Atavi is an interactive genealogical data visualization tool. It uses XSLT to transform XML data into SVG (Scable Vector Graphics) images. Deploy it as a Java servlet and explore visualizations from a browser that supports SVG. GEDCOM import is planned.

The Crosswise project is a web-based community event calendar that adds modular data analysis and visualization, and communication methods, to provide community organizations with a powerful event planning, collaboration and analysis tool.

Diktyologia is software for investigating complex systems with advanced methods of network theory. The package allows for analysing statistical properties of directed intercausal networks that are represented in form of cy.prus XML files.

Diagram (JGraph) driven simulator. Bondgraphs > nonlinear differantial system > plot: implemented for economics and ecology. Network analysis: emergy propagation implemented. Would also fit for electronics, mechanics, cost, GWP, footprint analysis.

EyeMap is a visualization and analysis tool for text reading eye movement data. It can process Unicode, proportion/non-proportion and spaced/unspaced reading materials, which supports various languages and experiment methods.

Controversial ideas of Williamson, Margulis & others suggest speciation by hybridizing might be more common than originally thought. Taking this concept to the nth degree & assuming that indeed, speciation mostly occurs by hybridizing events, not the accumulation of mutations or genetic drift, here is a catalogueoflife2gedcom converter. It allows the tree of life to be displayed as a human genealogy tree with hybridizing events depicted as "marriages." The idea then is that mutation accrual & genetic drift are the determining factors for "species maturation," not speciation itself. Unfortunately the Catalogue of Life Project, catalogueoflife.org, changed its database format more recently, so this converter only works on older versions of the data. In the last working version of the database, making the assumption that each taxonomic name, no matter what level, refers to an original real species & starting them all as female, over 2 million "species/persons" were generated.

Graphl is a generic graph visualization and manipulation tool written in Java. Graphl reads and writes RDF files, visualizes them in a flexible and customizeable way and allows users to edit them intuitively. Please see project homepage for more info...

Test for three-dimensional imaging: mental rotation of three-dimensional objects Shepard (R. Shepard, J. Metzler) Written with Delphi and OpenGL

A rich client to analyse data from a liquid-feedback (http://liquidfeedback.org/) instance, for now it's a 3d graph explorer to inspect the delegations. It's an application based on the eclipse platform (indigo). To be precise its a directed weighted multi graph browser in 3d.

An interactive tool for the simulation and visualization of the electromagnetic activity of the brain.

A C# implementation of LOGO which allows to reproduce many real world (complex) phenomena governed by local rules like traffic jams, gas diffusion, aggregation and percolation, ant systems and biological systems in general.

C++ and Python based open source graph visualization and analysis software, primarily intended for use in the analysis of social networks (other applications are also conceivable).

This project aims to develop open source psychometric data analysis software, including estimation software for Rasch and Item Response Theory (IRT) models for both dichotomous and polytomous test items.

Spatial Knowledge Base is a web based application for storing and searching of archaeological sites information. The software was written to improve access to cultural heritage information though the use of digital archiving, search technology, and GIS.

A project for the university of Potsdam. We try to parallize open source Project Sonvis with terracotta.

Data mines the voting record and other actions of Members of the UK Parliament. Extracts information from the parliament website and stores it in a database. Provides tools to analyse the information, producing statistics and tables about the MPs.
