Wandora is a general purpose information extraction, management, and publishing environment based on TopicMaps and Java. Wandora has several data storage options, rich data extraction, import and export capabilities and embedded server.
The TM4L Editor is an ontology editor allowing the user to build ontology-driven educational repositories using TopicMaps. The TM4L Editor is TopicMaps-based, thus the main objects that it manipulates are topics (representing domain ontology concepts), relationships between them, resources, and contexts (represented by themes). It includes four different sections (views): Topic Map, Topics, Relationships, and Themes. It is implemented in Java.
Graph visualization using hyperbolic geometry (hyperbolic trees, but also general graphs).
Applications cover web site structures, topicmaps, organisational charts and wikis.
A framework for building, deploying and managing well-described REST-ful Web services, including REST-ful Web Services realizations for RSS, XML TopicMaps, Structured Arguments, and Workflow.
TopicMapTools allows the creation, manipulation and visualization of XML TopicMaps. It is based on the TM4J framework. The editor can be used in genealogy for the visualisation of e.g. family trees.
Semblog allows TopicMaps-based semblogging (semantic blogging), i.e. blogging enhanced with semantic categories and relations represented with TopicMaps. It extends the Java-based Blojsom (blojsom.sf.net) via TMAPI (tmapi.sf.net).
TM4J is a topic map engine implemented entirely in Java. Topicmaps are a standard paradigm for the interchange of knowledge structures. This project aims to produce a complete suite of tools for creating, processing and publishing topic map information.
HyperSpider (Java app) collects the link structure of a website. Data import/export from/to database and CSV-files. Export to Graphviz DOT, Resource Description Framework (RDF/DC), XML TopicMaps (XTM), Prolog, HTML. Visualization as hierarchy and map.
Nexist is being developed based on a few hypotheses regarding TopicMaps (XTM) as an interface to a collaborative knowledge repository system. Nexist is a reference implementation for further collaborative development.
