چکیده
The Semantic Web is based on XML and RDF as its fundamental standards for ex changing and storing information on the World Wide Web SeLeNe will manage RDF descriptions of learning objects and users and will need to provide reactive functionality over such metadata We begin this report by summarising which aspects of the user re quirements identi ed in Deliverable will be provided by SeLeNe s reactive functionality and discussing why event condition action ECA rules are a natural candidate for imple menting this kind of functionality We then describe a language for ECA rules on XML and a prototype implementation of this language We next describe a language for ECA rules operating on a graph triple representation of RDF We nally describe the architec ture of a distributed deployment of such RDF ECA rules Along the way we identify some technical challenges and directions of further work necessary for the two languages and for the architecture London UK Jan

SeLeNe – Self E-Learning Networks
Learning objects are increasingly seen as key to a technology-based revolution in education and training, even to an emerging global knowledge economy. An international effort is underway to formulate standards that will enable Learning Object (LO) reuse and exchange among multiple educational settings, instructors, courses and institutions. The scope of this deliverable is to appropriately def...
متن کاملPersonalisation Services for Self E-learning Networks
This paper describes the personalisation services designed for self e-learning networks in the SeLeNe project. A self e-learning network consists of web-based learning objects that have been made available to the network by its users, along with metadata descriptions of these learning objects and of the network’s users. The proposed personalisation facilities include: querying learning object d...
متن کاملAdaptive Personalisation in Self e- Learning Networks
This paper presents some of the personalisation services designed for self e-learning networks in the SeLeNe project. A self e-learning network consists of web-based learning objects that have been made available to the network by its users, along with metadata descriptions of these learning objects and of the network’s users. The architecture of the network is distributed and service-oriented....
متن کاملPersonalisation and Trails in Self e-Learning Networks
This deliverable begins with a discussion of one level at which the process of searching for learning objects in a SeLeNe can be personalised. This involves the specification of the semantics of a SeLeNe User Profile, which takes some elements from existing learner profile schemes and adds extra custom elements where existing schemes fail to provide the expressiveness necessary for effective pe...
متن کاملSeLeNe – Self E-Learning Networks
In this report we propose a set of services that are applicable in the case of SeLeNe in alignment to the Open Grid Services Architecture (OGSA). In general, a service-based architecture is proposed that allows a user to submit requests to the SeLeNe Network, viewed as a whole, for the completion of some specific task. At this point, the SeLeNe project concentrates on providing services for the...
