XML RDF Digital libraries Query Search engine
A query interface towards XML document collections. The interface is automatically tailored to the document structure, as described by its XML Schema. External schema annotation in RDF contains information used to dynamically build the interface adapted to users characteristics and support her/him in formulating semantically correct queries. The architecture is fully compliant with web standards and design principles. The user can navigate the structure and prepare the query. Queries are prepared in an intermediate format that can be translated into different search engines. In preparing the query, the user can have access to ontologies or linguistic resources via web services.The user interface is dynamically created on the basis of information managed by the Administrator, and is capable of helping the user in expressing all the queries (s)he is interested in, assuring their correctness and supplying almost all the features supported by the search engine in the background. For each element, the system is well aware of its semantics and constraints, which can be shown to the user. The interface has been developed in Open Source Software environment.
