Resource Aggregation Model for Learning, Education and Training (RAMLET) Working Group 13
Resource Aggregation Models for Learning, Education and Training
Resource aggregation is the process of gathering digital resources, describing their structure, and often collecting or referring to their metadata so that the resulting resource aggregation can be used for transmission, storage, and delivery to users. Individual communities have developed different aggregation formats, each focusing on that community's special needs and requirements. There is a need to exchange resource aggregations between communities that may be using different aggregation formats. In these cases, it is necessary to map between aggregation formats.
The IEEE LTSC WG13 RMLT Working Group is defining a conceptual model that includes an ontology and a nomenclature for enabling the interpretation of externalized representations of digital aggregates of resources for learning, education, and training applications. The conceptual model facilitates interoperability by providing an ontology that can be used to represent and compare a variety of resource aggregation formats.
Interoperability may be achieved by the creation of crosswalks among the various aggregation standards and specifications. Five mapping recommended practices for some of the commonly used aggregation formats (IMS CP, MPEG-21 DID, METS, ATOM and OAI-PMH ORE) expressed as mappings to the core ontology are also being developed.
In addition, the conceptual model standard may serve as a common reference for the development and evolution of standards and specifications for resource aggregations and may assist the development of profiles that maximize interoperability between the various aggregation formats.
The working group has completed all research for the standard, and a draft standard is expected to be available for balloting by the end of May.
The working group has completed most of the research for creating the associated mapping recommended practices. Drafts are expected to be available for balloting within 3 months after balloting has started for the standard.
Public Working Group Artifacts:
RAMLET Project Description: Developing a reference model for resource aggregation for learning, ecucation, and training. This document describes the Ramlet project to produce an IEEE standard that will define a reference model for resource aggregation.
RAMLET Conceptual Overview: The LTSC Resource Models for Learning, Education, and Training (RAMLET) Working Group is undertaking a project to produce an IEEE standard that will define a conceptual model for digital aggregations of resources for learning, education, and training applications. The standard will facilitate interoperability by enabling the interpretation of external representations of resource aggregations and their properties. This document provides an overview of the conceptual model.RAMLET Use cases: This document describes several use cases that were used to inform the approach to the development of the conceptual model that will described in the standard..
RAMLET Ontology files are available through the IEEE download site and can be accessed from the IEEE Mentor site for RAMLET.
