The Debye environment for Web data management

The paper discusses the Debye (Data Extraction By Example) environment which lets users extract and manage semistructured data available from Web sources, using an extended form of nested tables as its fundamental paradigm. Currently, the Debye tools are fully implemented as prototypes for applications that use data from heterogeneous Web sources. For instance, developers have recently used Debye to build a repository that integrates data from the digital libraries of several universities.
