Policy-Carrying, Policy-Enforcing Digital Objects
Sandra Payette, Carl Lagoze
We describe the motivation for moving policy enforcement for access control down to the digital object level. The reasons for this include handling of item-specific behaviors, adap…
Flexible and Extensible Digital Object and Repository Architecture (FEDORA)
Sandra Payette, Carl Lagoze
We describe a digital object and respository architecture for storing and disseminating digital library content. The key features of the architecture are: (1) support for heterogen…
Web Synchronization Simulations using the ResourceSync Framework
Bernhard Haslhofer, Simeon Warner, Carl Lagoze +4
Maintenance of multiple, distributed up-to-date copies of collections of changing Web resources is important in many application contexts and is often achieved using ad hoc or prop…
ResourceSync: Leveraging Sitemaps for Resource Synchronization
Bernhard Haslhofer, Simeon Warner, Carl Lagoze +4
Many applications need up-to-date copies of collections of changing Web resources. Such synchronization is currently achieved using ad-hoc or proprietary solutions. We propose Reso…
Semantic Tagging on Historical Maps
Bernhard Haslhofer, Werner Robitza, Carl Lagoze +1
Tags assigned by users to shared content can be ambiguous. As a possible solution, we propose semantic tagging as a collaborative process in which a user selects and associates Web…
Resolving Author Name Homonymy to Improve Resolution of Structures in Co-author Networks
Theresa Velden, Asif-ul Haque, Carl Lagoze
We investigate how author name homonymy distorts clustered large-scale co-author networks, and present a simple, effective, scalable and generalizable algorithm to ameliorate such…
Adding eScience Assets to the Data Web
Herbert Van de Sompel, Carl Lagoze, Michael L. Nelson +3
Aggregations of Web resources are increasingly important in scholarship as it adopts new methods that are data-centric, collaborative, and networked-based. The same notion of aggre…
A Web-Based Resource Model for eScience: Object Reuse & Exchange
Carl Lagoze, Herbert Van de Sompel, Michael Nelson +3
Work in the Open Archives Initiative - Object Reuse and Exchange (OAI-ORE) focuses on an important aspect of infrastructure for eScience: the specification of the data model and a…
Object Re-Use & Exchange: A Resource-Centric Approach
Carl Lagoze, Herbert Van de Sompel, Michael L. Nelson +3
The OAI Object Reuse and Exchange (OAI-ORE) framework recasts the repository-centric notion of digital object to a bounded aggregation of Web resources. In this manner, digital lib…
Pathways: Augmenting interoperability across scholarly repositories
Simeon Warner, Jeroen Bekaert, Carl Lagoze +3
In the emerging eScience environment, repositories of papers, datasets, software, etc., should be the foundation of a global and natively-digital scholarly communications system. T…
Representing Contextualized Information in the NSDL
Carl Lagoze, Dean Krafft, Tim Cornwell +3
The NSDL (National Science Digital Library) is funded by the National Science Foundation to advance science and match education. The inital product was a metadata-based digital lib…
Metadata aggregation and "automated digital libraries": A retrospective on the NSDL experience
Carl Lagoze, Dean Krafft, Tim Cornwell +3
Over three years ago, the Core Integration team of the National Science Digital Library (NSDL) implemented a digital library based on metadata aggregation using Dublin Core and OAI…
An Information Network Overlay Architecture for the NSDL
Carl Lagoze, Dean B. Krafft, Susan Jesuroga +3
We describe the underlying data model and implementation of a new architecture for the National Science Digital Library (NSDL) by the Core Integration Team (CI). The architecture i…
Fedora: An Architecture for Complex Objects and their Relationships
Carl Lagoze, Sandy Payette, Edwin Shin +1
The Fedora architecture is an extensible framework for the storage, management, and dissemination of complex objects and the relationships among them. Fedora accommodates the aggre…
Core Services in the Architecture of the National Digital Library for Science Education (NSDL)
Carl Lagoze, William Arms, Stoney Gan +12
We describe the core components of the architecture for the (NSDL) National Science, Mathematics, Engineering, and Technology Education Digital Library. Over time the NSDL will inc…
Using Query Mediators for Distributed Searching in Federated Digital Libraries
Naomi Dushay, James C. French, Carl Lagoze
We describe an architecture and investigate the characteristics of distributed searching in federated digital libraries. We introduce the notion of a query mediator as a digital li…
The Computing Research Repository: Promoting the Rapid Dissemination and Archiving of Computer Science Research
Joseph Y. Halpern, Carl Lagoze
We describe the Computing Research Repository (CoRR), a new electronic archive for rapid dissemination and archiving of computer science research results. CoRR was initiated in Sep…
