This is a list of repositories and databases for open data.

zembly is a new kind of application development environment that lends the power of the crowd to you, so you can do more, faster. It's kind of like a wiki, but for applications.

Glasshouse by Green Phosphor is a gateway which can take a database query or a spreadsheet and place a 3D representation of it into a virtual world. Users can see data, and drill into it; re-sort it; explore it interactively - all from within a virtual world. Glasshouse produces graphs which are avatars of the data itself.

The HuWY project aims to support young people's eParticipation in policies about the Internet and its governance, through a distributed discussion. HuWY partners provide information, support and organise influential audiences for young people's suggestions. The Hub websites hold supporting information and structured space for results and feedback from policy-makers. Young people choose the topics and questions, host the discussions on their web pages and post the results on the Hubs.

Purpose 1. Act as a central point of reference and support for people who think they are interested in open data in science. 2. Identify practices of early adopters, collecting data and developing guides. 3. Act as a hub for the development of low cost, community driven projects around open data in science.

Open Data Commons is the home of a set of legal 'tools' to help you provide and use open data.

Extreme Tagging Systems allow for tagging the tags and tagging relations between the tags.

The concept of representation format, or type, permeates all technical areas of digital repositories. Policy and processing decisions regarding object ingest, storage, access, and preservation are frequently conditioned on a per-format basis. In order to achieve necessary operational efficiencies, repositories need to be able to automate these procedures to the fullest extent possible. JSTOR and the Harvard University Library are collaborating on a project to develop an extensible framework for format validation: JHOVE (pronounced "jove"), the JSTOR/Harvard Object Validation Environment.

JSTOR is a not-for-profit organization dedicated to helping the scholarly community discover, use, and build upon a wide range of intellectual content in a trusted digital archive. Our overarching aims are to preserve a record of scholarship for posterity and to advance research and teaching in cost-effective ways. We operate a research platform that deploys information technology and tools to increase productivity and facilitate new forms of scholarship. We collaborate with organizations that can help us achieve our objectives and maximize the benefits for the scholarly community

Computing all human knowledge from the web

We are often told that the best things in life are free, but few have ever tried to build it into a business model. Yet it is curious that while financial capitalism is in global meltdown, a completely different kind of entrepreneurial activity - call it commune-ism - is rising, from an admittedly low base.

What if you could contribute to a computational (Map-Reduce) job by simply pointing your browser to a URL? Surely your social network wouldn't mind opening a background tab to help you crunch a dataset or two! Instead of focusing on high-throughput proprietary protocols and high-efficiency data planes to distribute and deliver the data, we could use battle tested solutions: HTTP and your favorite browser.

The three most important aspects of an Open Science model are: 1) Open Access to scientific journals; 2) access to the raw material as Open Data; and 3) access to the transparent Open Process of the research methodologies itself.
