SHORE (Semantic Hypertext Object Repository) is a hypertext repository that stores data about documents and data described by documents. Access to this information is provided as hypertext. The repository stores objects that appear in documents, together with their relations in a semantic net. Hypertext navigation follows these relations in the semantic net. The SHORE server works as an HTTP server, and the client is a standard Web browser. The repository uses PROLOG as its query language and the XSB system as its query engine.
Annotatio is an implementation of a client and a server based on the W3C Annotea protocol. It allows you to create and share annotations to various types of documents. Most people can use this program to save comments to HTML documents, but it also supports other types of annotations and XML-like documents. In opposition to the current implementation of the W3C, Annotatio will save enhanced information of the annotation's positioning within the document, which will allow positing the annotation even if the location or structure of the original document has changed. In local mode, it will save all annotations locally, and in remote mode, it will save the annotations on a central Annotea-compatible server, such as Annotatio Server.
The Video Performance Evaluation Resource (ViPER) is a toolkit of Java programs and scripts that enables evaluation of video processing algorithms. This includes a markup tool for video, a performance evaluation tool that compares how well result data matches ground truth video metadata, and scripts and systems for running sets of experiments.
Red-Piranha is a search system that can actually learn what you are looking for. It can be used as a Web page, command line, or XML-WebService, so it will work with most languages, including Java, Perl, C#/.NET, and PHP. It includes learning abilities for the Desktop/Internet search functionality. All feedback from the user is stored in (editable) XML and RDF, and is used by the system to improve the quality of searches.
ConceptBase is a multi-user meta-database system based on a deductive object manager. It is mainly intended for conceptual modeling and coordination in design environments. The system implements O-Telos, a dialect of Telos that amalgamates properties of deductive and object-oriented languages.
COCANWIKI is a full-featured Wiki and content management system. It has many unique features not found in any other Wikis including live preview when editing, advanced navigation (including the ability to follow links in both directions), PIM/calendar extensions, user permissions, customisable page layouts, virtual hosting (handling more than one Wiki per server), search, anti-spam, and email notifications.
TM4J is a topic map processing toolkit and a set of topic map processing tools. Topic maps are an ISO standard for the interchange of information structures which can be used to represent ontologies, business data and processes, individual knowledge and opinions, and more. The goal of the TM4J project is to develop high-quality, Open Source software for the creation, manipulation, and exchange of topic maps.
