Patacritism is a project to develop interpretive tools for online humanities.

A small, digital book startup thinks it has a solution to the age-old student lament: overpriced textbooks that have little value when the course is over. The answer? Make them open source -- and give them away.

Panda, an open source project, will let any site owner willing to do a little coding and integration work to allow user video uploads and playback. Think YouTube in a box. The software itself is free and will run on Amazon Web Services EC2, S3 and SimpleDB. You'll have to pay for the Amazon services, but this is a nice step forward from a variety of existing paid services out there like Zencoder, SesameVault and Hey!Watch. Panda handles all aspects of uploading, transcoding and streaming, handing things off to a Flash player like JW FLV Player by default.

The OBO Foundry is a collaborative experiment involving developers of science-based ontologies who are establishing a set of principles for ontology development with the goal of creating a suite of orthogonal interoperable reference ontologies in the biomedical domain. The groups developing ontologies who have expressed an interest in this goal are listed below, followed by other relevant efforts in this domain.

OpenSocial's API reference describes a number of classes ('Person', 'Name', 'Email', 'Phone', 'Url', 'Organization', 'Address', 'Message', 'Activity', 'MediaItem', 'Activity', …), each of which has various properties whose values are either strings, references to instances of other classes, or enumerations. I'd like to make them usable beyond the confines of OpenSocial, so I'm making an RDF/OWL version. OpenSocial's schema is an attempt to provide an overarching model for much of present-day mainstream 'social networking' functionality, including dating, jobs etc. Such a broad effort is inevitably somewhat open-ended, and so may benefit from being linked to data from other complementary sources.

By integrating heterogeneous original data with uniform RDF format, creating additional ontology mappings between GO terms, and introducing a set of reasoning rulebases, we proposed a RDF model GORouter.

CoW is a "Controllable Wiki" and CMS that supports collaborative document creation with asynchonous off-line editing. CoW is desiged to make it easy to add interaction to static websites, and to support concurrent editing and off-line working with straightforward synchronisation (using Subversion). The system also serves as a test-bed for experiments in controlled languages for round-trip ontology engineering (from the GATE project: http://gate.ac.uk/).

SWiM is a semantic wiki for collaboratively building, editing and browsing a mathematical knowledge base. Its pages, containing mathematical theories, are stored in OMDoc, a markup format for mathematical knowledge. Our long-term objective is to develop a software that facilitates the creation of a shared, public collection of mathematical knowledge (e.g. for education) and serves work groups of mathematicians as a tool for collaborative development of new theories.

It produces descriptions of individuals (e.g., items for sale, museum exhibits) and classes (e.g., types of exhibits) in English and Greek from OWL DL ontologies. The ontologies must have been annotated in RDF with linguistic and user modeling resources. We demonstrate a plug-in for Protege that can be used to produce these resources and to generate texts by invoking NaturalOWL. We also demonstrate how NaturalOWL can be used by robotic avatars in Second Life to describe the exhibits of virtual museums. NaturalOWL demonstrates the benefits of Natural Language Generation (NLG) on the Semantic Web. Organizations that need to publish information about objects, such as exhibits or products, can publish OWL ontologies instead of texts. NLG engines, embedded in browsers or Web servers, can then render the ontologies in multiple natural languages, whereas computer programs may access the ontologies directly.

The GridSphere portal framework provides an open-source portlet based Web portal. GridSphere enables developers to quickly develop and package third-party portlet web applications that can be run and administered within the GridSphere portlet container. Here you will find the GridSphere portal framework available for download and documentation related to the installation and development of portlets using GridSphere.

DynaQ stands for 'Dynamic Queries for document based, personal information spaces'. The goal of the project is to conceptualise and to develop a prototypical inquiry system to explore the personal information space, that supports the user with the help of the searching paradigm orienteering. The document-based, personal information space of the user constitutes by all documents on his computer. Included are documents of several file formats (e.g. *.pdf), but also the users emails. Also included are all available meta informations and existing semantic informations according to the documents. Users that are not aware of the scientific context of the project can just think of DynaQ as an desktop search engine.

SMOB is a distributed / decentralised microblogging system built on RDF and Semantic Web technologies, mainly SIOC and FOAF. Currently, we have simple prototypes of a publishing and an aggregating service, less than 100 lines of PHP code each. Code at http://code.google.com/p/smob/

The Sematic Web Client Library represents the complete Semantic Web as a single RDF graph. The library enables applications to query this global graph using SPARQL- and find(SPO) queries. To answer queries, the library dynamically retrieves information from the Semantic Web by dereferencing HTTP URIs and by following rdfs:seeAlso links. The library is written in Java and is based on the Jena framework.

Mahout's goal is to build scalable, Apache licensed machine learning libraries. Initially, we are interested in building out the ten machine learning libraries detailed in http://www.cs.stanford.edu/people/ang//papers/nips06-mapreducemulticore.pdf using Hadoop. While these algorithms are our initial focus, we welcome contributions of other machine learning approaches.

Software developed by DART@UQ is released under an open source license [BSD-like]. Binary versions of the software are available for download.

MySQLicious provides automated mirroring/backups of Delicious bookmarks into a MySQL database.

ARC is a flexible RDF system for semantic web and PHP practitioners. It's free, open-source, easy to use, and runs in most web server environments. RDF and SPARQL for LAMP systems

Cytoscape is an open source bioinformatics software platform for visualizing molecular interaction networks and integrating these interactions with gene expression profiles and other state data.
