Chapter 7: Dataspaces [chapter]

Cornelia Hedeler, Khalid Belhajjame, Norman W. Paton, Alessandro Campi, Alvaro A. A. Fernandes, Suzanne M. Embury
2010 Lecture Notes in Computer Science  
As such, dataspaces join a long stream of research activities that aim to build tools that simplify integrated access to distributed data.  ...  The vision of dataspaces is to provide various of the benefits of classical data integration, but with reduced up-front costs, combined with opportunities for incremental refinement, enabling a "pay as  ...  The deployment phase, which may not be required, for example, in the case of a personal dataspace residing on a single desktop computer, could include enabling access to the dataspace for users or moving  ...

iDM: A Unified and Versatile Data Model for Personal Dataspace Management

Jens-Peter Dittrich, Marcos Antonio Vaz Salles
2006 Very Large Data Bases Conference  
As iDM allows the representation of the whole personal dataspace [20] of a user in a single model, it is the foundation of the iMeMex Personal Dataspace Management System (PDSMS) [16, 14, 47].  ...  We present the iMeMex Data Model (iDM) for personal information management. iDM is able to represent unstructured, semi-structured and structured data inside a single model.  ...  We also thank Shant Karakashian for providing the L A T E X2iDM converter.  ...

Dataspaces: Fundamentals, Principles, and Techniques [chapter]

Edward Curry
2019 Real-time Linked Dataspaces  
Focusing on the management of the information on a person across various sources, from their desktop [86] and mobile devices to their presence on social networks.  ...  These works have provided a number of definitions for a dataspace as captured in Table 3 .1; most of these build on the initial concept from [2] .  ...

Indexing dataspaces

Xin Dong, Alon Halevy
2007 Proceedings of the 2007 ACM SIGMOD international conference on Management of data - SIGMOD '07  
Much of the user interaction with dataspaces involves exploring the data, and users do not have a single schema to which they can pose queries.  ...  Unlike data-integration systems that also offer uniform access to heterogeneous data sources, dataspaces do not assume that all the semantic relationships between sources are known and specified.  ...  Acknowledgments We would like to thank Magda Balazinska, Mike Cafarella, Shawn Jeffery, Dan Suciu, Anthony Tung and the anonymous reviewers for many helpful discussions and comments.  ...

Design and implementation of a dataspace model for e-Science applications

Adnan Muslimovic
2008 unpublished
The research challenge motivating the work on this Thesis is faced by the vision of dataspaces which main idea is to abstract from the underlying data source structures by providing a system managing various  ...  The heterogeneous and distributed mix of various data sources nowadays requires intelligent management systems in order to provide an unified view over such a data.  ...  The iMeMex Personal Dataspace Management System introduces a logical layer on top of the data sources that provides a mechanism for managing personal logical and physical information. iMeMex addresses  ...

Databases and Information [chapter]

2001 Law Enforcement Information Technology  
We provide an evaluation of a state-of-the-art XML-aware database implementing a file system.  ...  Since file systems are structured hierarchically they can be mapped to XML and as such stored in and queried by an XML-aware database.  ...  As soon as the demand for querying and retrieval preponderates the processing of file systems, using semi-structured database techniques to enhance file system capabilities is a clear option.  ...
