Digital libraries have been rather successful in supporting learning activities by providing learners with access to information and knowledge. However, this level of support is passive to learners and interactive and collaborative learning cannot be easily achieved. In this paper, we study how digital libraries could be extended to serve a more active role in collaborative learning activities. We focus on developing new services to support a common type of learning activity, field study, in a geospatial context. We propose the concept of personal project space that allows individuals to work in their personalized environment with a mix of private and public data and at the same time to share part of the data with team members. To support the portability of the resources in our digital library, the selected resources can be exported in an organized manner.

The personalized project space is an important feature in G-Portal that supports individual and group learning activities. Within such a space, its owner can create, delete, and organize metadata referencing learning objects on the Web. Browsing and querying are among the functions provided to access the metadata. In addition, new schemas can be added to accommodate metadata of diverse attribute sets. Users can also easily share metadata across different projects using a “copy-and-paste” approach. Finally, a viewer to support offline viewing of personalized project content is also provided.

Defining a research agenda for geographical learning tasks with the G-portal digital library
2004, Hedberg, John G., Chang, Chew Hung, Lim, Ee Peng, Sun, Aixin, Teh, Tiong Sa, Goh, Dion Hoe Lian, Theng, Yin Leng
For many years learning management systems have been focused on providing resources for students. More recently, the growth of digital repositories has provided resources that can be tagged and searched independently of a course structure. G-portal provides resources specifically tagged for geographical learning tasks and provides a project space in which students can collaborate, create resources and share these resources amongst themselves. This paper reviews the research issues surrounding G-portal using activity theory as a framework and defines a research agenda based on the capabilities of G-portal. In particular, issues of information organisation, issues of usability, search strategies and retrieval techniques, multimodality of representation, transduction of information and representation of geographic and spatial information will be examined. The research agenda focuses on three areas: information organisation and representation; the capabilities of the G-Portal application and its ability to integrate and retrieve information and geographical task; and the ease with which students are able to undertake and complete learning tasks about geographical phenomena.
