Ontology Repository

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.

X-Media addresses the issue of knowledge management in complex distributed environments. It will study, develop and implement large scale methodologies and techniques for knowledge management able to support sharing and reuse of knowledge that is distributed in different media (images, documents and data) and repositories (data bases, knowledge bases, document repositories, etc.). The project started in March 2006 and will last for 4 years. It has a budget topping Euro 13.6M, (9.9M from the EU). 15 partners are involved from UK, Germany, Italy, France, Slovenia, Greece and Norway.

Systems Biology Linker (Sybil) is a platform for the integration of BioPAX and SBML. It is part of the Virtual Cell but also a useful tool for any SBML and BioPAX integration, in other words for any one who wants to use BioPAX with an SBML-capable platform or vice versa. While Sybil can be used as an intelligent conversion tool between SBML and BioPAX, it is primarily intended for building a joint repository for SBML and BioPAX data, where links between SBML elements and BioPAX objects are maintained by SBPAX. Sybil uses SYBREAM for most of the intelligent work involved in building the SBML-SBPAX-BioPAX joint repository.

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

The National Center for Biomedical Ontology is a consortium of leading biologists, clinicians, informaticians, and ontologists who develop innovative technology and methods allowing scientists to create, disseminate, and manage biomedical information and knowledge in machine-processable form. Our visionis that all biomedical knowledge and data are disseminated on the Internet using principled ontologies, such that they are semantically interoperable and useful for improving biomedical science and clinical care. Our resources include the Open Biomedical Ontologies (OBO) library, the Open Biomedical Data (OBD) repositories, and tools for accessing and using this information in research. The Center collaborates with biomedical researchers conducting Driving Biological Projects to enable outside research and stimulate technology development in the Center. The Center undertakes outreach and educational activities (Biomedical Informatics Program) to train future researchers to use biomedical ontologies and related tools with the goal of enhancing scientific discovery.

This paper not only shares the designing and implementation challenges faced by the KnowGenesis team, but also presents the approach used to match the user requirements with the Library design. Based on the lessons learned during the process, the paper also presents specific set of guidelines and recommends methodologies that can provide critical assistance for developing and managing medium and large-scale repositories.

/facet is a generic browser for heterogeneous semantic web repositories. The browser works on any RDFS dataset without any additional configuration.

KHarvester (Informal Knowledge Harvester) is a SOA layer which collects RDF data from web pages. It provides REST based Web Services for managing data available on Social Semantic Information Sources (SSIS): semantic blogs, semantic wikis, and JeromeDL (the Social Semantic Digital Library). These Web Services allow saving harvested data in the informal knowledge repository, and providing them in a form of informal Learning Objects (LOs) that are described accroding to LOM (Learning Object Metadata) standard. Also, IKHarvester is an extension to Didaskon system. Didaskon (διδάσκω - gr. teach) delivers a framework for composing an on-demand curriculum from existing Learning Objects provided by e-Learning services (formal learning). Moreover, the system derives from SSIS which provide informal knowledge. Then, the selection and work-flow scheduling of Learning Objects is based on the semantically annotated specification of the user's current skills/knowledge (pre-conditions), anticipated resulting skills/knowledge (goal) and technical details of the clients platform.

In 2000, Nicola Guarino and Chris Welty published a series of papers on what came to be named OntoClean, a methodology for ontology-driven conceptual analysis. The methodology has been receiveing increasing levels of attention in various communities, and on this page we hope to provide a central repository for information regarding OntoClean, to help keep the community in touch with how the methodology is being implemented, supported, used, extended, and referenced.

Public Data Sets on AWS provides a centralized repository of public data sets that can be seamlessly integrated into AWS cloud-based applications. AWS is hosting the public data sets at no charge for the community, and like all AWS services, users pay only for the compute and storage they use for their own applications.

Welcome to the Social Media Classroom and Collaboratory. It's all free, as in both "freedom of speech" and "almost totally free beer." We invite you to build on what we've started to create more free value. The Social Media Classroom (we'll call it SMC) includes a free and open-source (Drupal-based) web service that provides teachers and learners with an integrated set of social media that each course can use for its own purposes-integrated forum, blog, comment, wiki, chat, social bookmarking, RSS, microblogging, widgets , and video commenting are the first set of tools. The Classroom also includes curricular material: syllabi, lesson plans, resource repositories, screencasts and videos. The Collaboratory (or Colab), is what we call just the web service part of it. Educators are encouraged to use the Colab and SMB materials freely, and we host your Colab communities if you don't want to install your own.

17 November 2008 - The international open standards consortium, OASIS, has formed a new group to standardize a Web services interface specification that will enable greater interoperability of Enterprise Content Management (ECM) systems. The new OASIS Content Management Interoperability Services (CMIS) Technical Committee will advance an open standard that uses Web services and Web 2.0 interfaces to enable information to be shared across Internet protocols in vendor-neutral formats, among document systems, publishers and repositories, within and between companies.

To manage information quality (IQ) effectively, one needs to know how IQ changes over time, what causes it to change, and whether the changes can be predicted. In this paper we analyze the structure of IQ change in Wikipedia, an open, collaborative general encyclopedia. We found several patterns in Wikipedia's IQ process trajectories and linked them to article types. Drawing on the results of our analysis, we develop a general model of IQ change that can be used for reasoning about IQ dynamics in many different settings, including traditional databases and information repositories.

Annotating is a pervasive element of scholarly practice for both the humanist and the scientist. It is a method by which scholars organize existing knowledge and facilitate the creation and sharing of new knowledge. It is used by individual scholars when reading as an aid to memory, to add commentary, and to classify. It can facilitate shared editing, scholarly collaboration, and pedagogy. Over time annotations can have scholarly value in their own right. Yet scholars remain dissatisfied with the options available for annotating digital resources. Scholars wanting to annotate have to learn different annotation clients for different content repositories, have no easy way to integrate annotations made on different systems or created by colleagues using other tools, and are often limited to simplistic and constrained models of annotation. The importance of annotating as a scholarly practice coupled with the real-world limitations of existing practices and tools supporting annotation of digital content has had a retarding effect on the growth of digital scholarship and the level of digital resource use by scholars.

NutchWAX ("Nutch + Web Archive eXtensions" ) searches web archive collections. The Web Archive eXtensions (WAX) include adaptation of the Nutch fetcher step to go against web archives rather than crawl the open net -- adaptation currently does Internet Archive ARC files only -- and plugins to add extra fields to the index that return an Archive Records' location in the repository, its collection name, etc.
