Towards the integration of digital library applications via web services for use in a scientific workspace

摘要

"Our project 'Generic Portals' focuses on the possibilities and problems created by the usage ofweb-technologies to support web-based Digital Library applications. We observe a divergenceof services in the sphere of structured resources and scientific libraries' services. Publications in the form of digital resources have introduced new dynamics into the information exchange in the scientific communities. The changes in the publication process are formed by so-called structured resources, whereas the resource can be seen as an encapsulated object. For the exchange of information we have only to know the interface of the structured resource indetail. W3C has published a working draft which includes a language named Web Service DescriptionLanguage (WSDL) for describing interfaces of services. A Web service interface is ashared connection between functional components of applications. We consider the requirementsfor the integration of DL-applications via Web services. We present an adapted processmodel for supply of DL-oriented Web services. Further we present a component-based approachto relate researchers' activities to so-called DL-oriented Web services. We obtaincriteria for the description of DL-oriented Web services based on the researchers' workingprocess. Finally, we present a brief overview what kind of Web technologies might be reused fora prototypical implementation of DL-oriented Web services." (author's abstract)
