XMDR+: An Extended XMDR Model for Supporting Diverse Ontological Relations

Abstract

SUMMARYMetadata registry (MDR) is based on the international standard ISO/IEC 11179. The committee of ISO/IEC JTC 1/SC 32, which had standardized the MDR, has started to improvise the MDR, and the improvised version is named extended MDR (XMDR). However, the XMDR does not fully support the ontology concept, and no method is available for mapping ontology registrations onto registries. To overcome the limitations of the outdated XMDR, this paper proposes an extended XMDR (XMDR+) framework. The XMDR+ framework provides a method for mapping of ontology registrations between the metadata registry and ontologies. To improve the functions of the XMDR, we have proposed herein a framework that is capable of defining a model that manages the relations not only among ontological concepts but also among instances, and guarantees the management and storage of their relationships for supporting valid relations of the ontologies.

Ontology Integration Framework Based on XMDR+

“…Existing XMDR does not fully support the ontology concepts, and no method is available for mapping ontology registrations onto registries. To overcome the limitations of the outdated XMDR, Jeong-Dong [6] proposed the XMDR+. The XMDR+ provides to support diverse ontological relations that can manage the schema-level as well as the instance-level and further presents a mapping method for ontology registration of ontology registrations between the metadata registry and ontologies.…”

“…Conceptually, ontology consists of two levels: schema and instance, each of which is designed and designed and developed by domain experts. Various distinct problems lie in ontology integration due to the matters concerning (i) how to express in which technical language, (ii) terminology, (iii) level of schema, (iv) level of instance and (v) system [6].…”

“…To improve the functions of the metadata registry [5], proposed framework that is capable of defining a model that manages the relations not only among ontological concepts but also within the instance-level and is also capable of consistently keeping and managing data through the mapping management function for ontology registration, named XMDR+ [6]. The XMDR+ applies ontology technologies for semantic extraction of data elements and interpretation of their relations.…”
