Improving LOM-Based Interoperability of Learning Repositories
نویسندگان
چکیده
This paper analyses the use of LOM Application Profiles for learning object repository interoperability. Based on an exemplifying use case the paper presents a case study, which aims at developing a LOM Application Profile to realized Smart Spaces for Learning. Finally, a schema is designed which selects the necessary LOM elements and makes a LOM-conformant extension to represent usage conditions and learning activities. This work is part of the Elena project, which focuses on integrating advanced educational mediators in a network of federated services.

Towards Interoperable Learning Object Repositories: The Ariadne Experience
In this paper, we present an approach for producing interoperable metadata by mapping metadata structures of application profiles into standard metadata structures. As a study case, we map the ARIADNE metadata structure into the LOM structure. We use XSLT to transform ARIADNE XML instances into IEEE LOM Instances. Finally, we validate the resulting LOM XML instances. The major contribution of t...
متن کاملThe LOM application profile for agricultural learning resources of the CGIAR
The international agricultural research centres of the CGIAR have established a repository for agricultural learning resources in collaboration with the ARIADNE Foundation. To make it easier to find these resources, an application profile, CG LOM Core, was developed on the basis of the IEEE Learning Object Metadata (LOM) standard. It defines the collection of metadata elements and value spaces ...

In order to achieve coherence and flexibility in multimedia-based learning units many authors recommend that the lesson components are structured as a graph. In a lesson graph, educational resources are encapsulated into learning objects (LO) along with their respective metadata (LOM) and are interconnected through different kinds of rhetorical and semantical relationships. Lesson graph LOs are...
متن کاملSearch and Delivery of Standardized Learning Resources Based on SOAP Messaging and Native XML Databases
With the progress of Web-based learning technologies, standardized digital repositories and learning management systems are becoming prevalent over time. The heterogeneity in underlying databases and access methods, however, makes it difficult to share and exchange the learning resources between them. In this paper, we propose an architecture for the search and delivery of learning resources. B...
متن کاملCase Study: Ontology for Metadata in e-Learning
Learning objects are a fundamental concept in new educational paradigms based on e-learning. These resources are not only content but also include metadata descriptions organized into categories, often in the form of an application profile of the IEEE LOM standard. These metadata descriptions facilitate the design, search, exchange and reuse of educational contents reachable through learning ob...
