Engineering an Open Web Syndication Interchange with Discovery and Recommender Capabilities
No full textWeb syndication has become a popular means of delivering relevant information to people online but the complexity of standards, algorithms and applications pose considerable challenges to engineers. This paper describes the design and development of a novel Web-based syndication intermediary called InterSynd and a simple Web client as a proof of concept. We developed format-neutral middleware that sits between content sources and the user. Additional objectives were to add feed discovery and recommendation components to the intermediary. A search-based feed discovery module helps users find relevant feed sources. Implicit collaborative recommendations of new feeds are also made to the user. The syndication software built uses open standard XML technologies and the free open source libraries. Extensibility and re-configurability were explicit goals. The experience shows that a modular architecture can combine open source modules to build state-of-the-art syndication middleware and applications. The data produced by software metrics indicate the high degree of modularity retained
Archival description in OAI-ORE
No full textThis paper proposes using OAI-ORE as the basis for a new method to represent and manage the description of archival collections. This strategy adapts traditional archival description methods for the contemporary reality of digital collections and takes advantage of the power of OAI-ORE to allow for a multitude of non-linear relationships, providing richer and more powerful access and description. A schema for representing finding aids in OAI-ORE would facilitate more sophisticated methods for modeling archival collection descriptions
Towards an Open Repository Environment
No full textRepositories used to be fairly monolithic systems, with a single object store, a tailored content model, and a dedicated application on top. The federation protocol OAI-PMH for content aggregation is an exception to this. However, we are still far away from an open repository environment, in which repositories interact on all levels with other agents (e.g. other repositories, added-value services, registries).
This paper creates a more fine-grained view on repository federation and analyses existing approaches with regard to four interoperability attributes: syntax, structure, semantics, and patterns. Among these attributes, the most evident gap pertains to interaction patterns between agents. Besides the prevalent client-pull and harvesting patterns, notification offers a more immediate and directed mechanism, enabling new federation scenarios and laying the grounds for open repository environments. Prototypes of the concepts presented here are being implemented in the scope of the project DARIAH, which establishes an e-Infrastructure for the humanities
Self-Assessment of a Long-Term Archive for Interdisciplinary Scientific Data as a Trustworthy Digital Repository
No full textLong-term preservation and stewardship of scientific data and research-related information are vitally important to future science and scholarship. Scientific data archives can offer capabilities for managing and preserving disciplinary and interdisciplinary data for research, education, and decision-making activities of future communities of users. Meeting the requirements for a trusted digital repository will help to ensure that today’s collections of scientific data will be available in the future. A continuing self-assessment of a long-term archive for interdisciplinary scientific data is being conducted to identify the additional steps needed for it to become a trustworthy repository. Recommendations include a strategy for collaborative organizational sustainability, a model for submission and workflow to ingest interdisciplinary scientific data into a repository, and a plan for facilitating intra-organizational transfer between repositories
ICE-Theorem - End to end semantically aware eResearch infrastructure for theses
No full textICE-TheOREM was a project which made several important contributions to the repository domain, promoting deposit by integrating the repository with authoring workflows and enhancing open access by prototyping new infrastructure to allow fine-grained embargo management within an institution without impacting on existing open access repository infrastructure.
In the area of scholarly communications workflows, the project produced a complete end-to-end demonstration of eScholarship for word processor users, with tools for authoring, managing and disseminating semantically-rich thesis documents fully integrated with supporting data. This work is focused on theses, as it is well understood that early career researchers are the most likely to lead the charge in new innovations in scholarly publishing and dissemination models.
The authoring tools are built on the ICE content management system, which allows authors to work within a word processing system (as most authors do) with easy-to-use toolbars to structure and format their documents. The ICE system manages both small data files and links to larger data sets. The result is research publications which are available not just as paper-ready PDF files but as fully interactive semantically aware web documents which can be disseminated via repository software such as ePrints, DSpace and Fedora as complete supported web-native and PDF publications.
ICE-TheOREM combined the Object Reuse and Exchange (OAI-ORE, IONSREPORT 2008) and SWORD-APP protocols to transfer content between a content management system, a thesis management system and multiple repository software packages and looked at ways to describe aggregate objects which include both data and documents, and to represent structure withing thesis documents. This can be generalized to domains other than chemistry. ICE-TheOREM has demonstrated how focusing on the use of the web architecture (including ORE) enables repository functions to be distributed between systems for complex, data-rich compound objects
Adding OAI-ORE Support to Repository Platforms
No full textThe Texas Digital Library (TDL) is a cooperative initiative of Texas universities. One of TDL’s core services is a federated collection of electronic theses and dissertations (ETDs) from its member schools. As this collection grew, the need for tools to manage the content exchange from the local to the federated repository became evident. This paper presents our experiences in adding harvesting support to the DSpace repository platform using the ORE and PMH protocols from the Open Archives Initiative. We describe our use case for a statewide ETD repository and the mapping of the OAI‐ORE data model to the DSpace architecture. We discuss our implementation that adds both dissemination and harvesting functionality to the repository. We conclude by discussing the architectural flexibility added to the TDL repository through this project
Policy-based Distributed Data Management Systems
No full textScientific research collaborations generate massive amounts of data that are assembled into collections, published in digital libraries, processed in data analysis pipelines, and preserved in reference collections. Policy-based data management systems minimize the amount of labor needed to manage the massive collections by automating the enforcement of management policies and the validation of assessment criteria. The goal is data management infrastructure that can be used to support all phases of the data life cycle, while minimizing the amount of labor needed to maintain the collection
Restoring Trust Relationships within the Framework of Collaborative Digital Preservation Federations
No full textThe authors extend their process for creating and establishing trust relationships to include steps for restoring trust relationships after catastrophic events. Part of this model will include best practices for business continuity relationships and will integrate trust models from Holland and Lockett (1998) and Ring and Van de Ven (1994) and how they can be applied to a process for trust restoration after periods of disaster or critical data loss. These models provide key frameworks for understanding how trust can be utilized for collaborative start points as well as for collaborative recovery points from physical natural disaster or critical data loss. Additionally, the authors will present findings from an audience poll conducted on May 15, 2009 during the presentation of this topic at the 4th International Conference on Open Repositories with additional conclusions and commentary
Author Identifiers in Scholarly Repositories
No full textBibliometric and usage-based analyses and tools highlight the value of information about scholarship contained within the network of authors, articles and usage data. Less progress has been made on populating and using the author side of this network than the article side, in part because of the difficulty of unambiguously identifying authors. I briefly review a sample of author identifier schemes, and consider use in scholarly repositories. I then describe preliminary work at arXiv to implement public author identifiers, services based on them, and plans to make this informatio
Authoring, Editing and Visualizing Compound Objects for Literary Scholarship
No full textThis paper presents LORE (Literature Object Re-use and Exchange), a light-weight tool designed to enable scholars and teachers of literature to author, edit and publish OAI-ORE-compliant compound information objects that encapsulate related digital resources and bibliographic re-cords. LORE provides a graphical user interface for creating, labelling and visualizing typed rela-tionships between individual objects using terms from a bibliographic ontology based on the IFLA FRBR. After creating a compound object, users can attach metadata and publish it to a re-pository (as an RDF graph) where it can be searched, retrieved, edited and re-used by others. LORE has been developed in the context of the Australian Literature Resource project (AustLit) and hence focuses on compound objects for teaching and research within the Australian literary studies community. However it can easily be tailored to support the creation of compound ob-jects for literary and bibliographic research more generally
