Catching the boat with Strudel

Mary Fernández, Daniela Florescu, Jaewoo Kang, Alon Levy, Dan Suciu
1998 Proceedings of the 1998 ACM SIGMOD international conference on Management of data - SIGMOD '98  
We describe our experience constructing several Web sites with Strudel and discuss the impact of potential users' requirements on Strudel's design.  ...  Second, the builder uses this model to declaratively define the Web site's structure by applying a "site-definition query" to the underlying data.  ...  STRUDEL is based on a semistructured data model of labeled, directed graphs.  ...

Using WG-Log Schemata to Represent Semistructured Data [chapter]

E. Damiani, B. Oliboni, L. Tanca, D. Veronese
1999 Database Semantics  
In this paper we discuss the possibility to represent synthetically semistructured information via a loose notion of schema: we say that data are semistructured when, although some structure is present  ...  We show how information encoded in a typical semistructured information model, as OEM, can be represented and queried by means of the WG-Log language, and how the TSIMMIS and WG-Log Web Query System can  ...  Acknowledgments The authors wish to thank A. Dovier, M. Baldi and F. Insaccanebbia for many useful discussions on the subject. Thanks are also due to H. Garcia-Molina and R.  ...

XML-based Components for Federating Multiple Heterogeneous Data Sources [chapter]

Georges Gardarin, Fei Sha, Tram Dang Ngoc
1999 Lecture Notes in Computer Science  
The results demonstrate the ability of XML with an associated query language (we use XML-QL) to federate various data sources on the Internet or on Intranets.  ...  This paper gives an overview of the XMLMedia system, a federated database system mediator using XML as federating model, built in the Esprit Project MIRO-Web.  ...  Acknowledgments We would like to thank Peter Fankhauser, Dana Florescu, Henri Laude and Patrick Valduriez for helpful discussions, particularly in the context of the MIRO-Web project.  ...

Integrating and querying web databases and documents

Carlos Garcia-Alvarado, Carlos Ordonez
2011 Proceedings of the 20th ACM international conference on Information and knowledge management - CIKM '11  
In this paper, we defend the idea of building web metadata repositories using relational databases as the main source and central data management technology of structured data, enriched by the semistructured  ...  Web document data include files, documents and web pages. Links between metadata and external documents are built with SQL queries.  ...  Semistructured data sources (i.e. documents, web pages, files) are valuable for describing and enriching structured data.  ...

Interactive Query and Search in Semistructured Databases [chapter]

Roy Goldman, Jennifer Widom
1999 Lecture Notes in Computer Science  
Semistructured graph-based databases have been proposed as well-suited stores for World-Wide Web data. Yet so far, languages for querying such data are too complex for casual Web users.  ...  Further, proposed query approaches do not take advantage of the interactive nature of typical Web sessions-users are proficient at iteratively refining their Web explorations.  ...  Implementation Status Our interactive query and search model, along with the necessary supporting features discussed in this paper, are under development within the Lore project.  ...

Database techniques for the World-Wide Web

Daniela Florescu, Alon Levy, Alberto Mendelzon
1998 SIGMOD record  
Acknowledgements The authors are grateful to the following colleagues who provided suggestions and comments on earlier versions of this paper: Serge Abiteboul, Gustavo Arocena, Paolo Atzeni, Jos e B l  ...  Since the data on the web is commonly semistructured (or worse), these languages still emphasize the ability to support semistructured features.  ...  Models for semistructured data have been based on labeled directed graphs Abi97, Bun97]. 1 In a semistructured data model, there is no restriction on the set of arcs that emanate from a given node in a  ...

An Entailment Relation for Reasoning on the Web [chapter]

François Bry, Sebastian Schaffert
2003 Lecture Notes in Computer Science  
As a consequence, additional data processing like data conversion from Web formats (e.g.  ...  Reasoning on the Web is receiving an increasing attention because of emerging fields such as Web adaption and Semantic Web.  ...  Semantic Web applications rely on declarative meta-data specifying the content of Web pages and Web sites and on description logic and/or ontology reasoning for processing these meta-data.  ...

Managing semistructured data with FLORID: A deductive object-oriented perspective

Bertram Ludäscher, Rainer Himmeröder, Georg Lausen, Wolfgang May, Christian Schlepphorst
1998 Information Systems  
We elaborate on the management of semistructured data and show h o w reachability queries involving general path expressions and the extraction of data paths in the presence of cyclic data can be handled  ...  | The closely related research areas management of semistructured data and languages for querying the Web have recently attracted a lot of interest.  ...  Acknowledgements | The authors thank the anonymous reviewers for many helpful comments.  ...

Metadata management for federated databases

Carlos Ordonez, Zhibo Chen, Javier García-García
2007 Proceedings of the ACM first workshop on CyberInfrastructure: information management in eScience - CIMS '07  
In general, there exists a lot of semistructured data elements outside the database represented by documents (files), created and updated by multiple users and programs.  ...  Metadata includes table and columns coming from logical data models corresponding to each database, as well as documents representing external semistructured data sources.  ...  Acknowledgments The third author is with Universidad Nacional Autónoma de México (UNAM) and was sponsored by the UNAM IT project "Macroproyecto de Tecnologías para la Universidad de la Información y la  ...
