115 ISO (the International Organization for Standardization) and IEC (the International Electrotechnical

116 Commission) form the specialized system for worldwide standardization. National bodies that are members of

117 ISO or IEC participate in the development of International Standards through technical committees

118 established by the respective organization to deal with particular fields of technical activity. ISO and IEC

119 technical committees collaborate in fields of mutual interest. Other international organizations, governmental

120 and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information

121 technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.

153 Interoperation among autonomous applications, such as Web services, is becoming important. To promote

154 interoperation among application systems, unambiguous and formal specifications of the systems, especially

155 of their inputs and outputs, are indispensable. Ontologies have a key role for that.

156 Several efforts to establish standards associated with ontologies have been made. But, most of them specify

157 languages or are based on some particular language. To promote ontology-based interoperation, in addition

158 to them, a generic framework for registering administrative and evolution information related to ontologies,

160 This part of ISO/IEC 19763 intends to provide a generic framework for registering administrative and evolution

167 The primary purpose of the multipart standard ISO/IEC 19763 is to specify a metamodel framework for

168 interoperability. This part of ISO/IEC 19763 specifies the metamodel that provides a facility to register

170 The metamodel that this part specifies is intended to promote interoperation among application systems, by

171 providing administrative and evolution information related to ontologies, accompanied with standardized

172 ontology repositories that register ontologies themselves in specific languages.

173 This part of ISO/IEC 19763 does not specify the metamodels of ontologies expressed in specific languages

174 and the mappings among them. They are specified in other specifications such as the Ontology Definition

226 NOTE1 An authoritative extent is used to determine whether a thing may use another thing. A thing may use another

227 thing if and only if the authoritative extent of the former is less than or equal to the authoritative extent of the

228 latter because the usage of the latter by the former does not affect the authoritative extent of the former since

229 the authoritative level of the latter is greater than or equal to the one of the former.

230 EXAMPLE A product with some authoritative extent can only use as its component a part with an authoritative extent

231 which is greater than or equal to the one of it, to keep its authoritative extent.

270 In each conformance level, the distinction between "strictly conforming" and "conforming" implementations is

271 necessary to address the simultaneous needs for interoperability and extensions. This part of ISO/IEC 19763

272 describes specifications that promote interoperability. Extensions are motivated by needs of users, vendors,

273 institutions, and industries, but are not specified by this part of ISO/IEC 19763.

274 A strictly conforming implementation may be limited in usefulness but is maximally interoperable with respect

275 to this part of ISO/IEC 19763. A conforming implementation may be more useful, but may be less

294 MFI Ontology registration consists of two packages: Basic_Model package and Evolution_Model package.

296 The Basic_Model package is used to register administrative information related to ontologies, independently

297 of the languages that are used to express them. The basic idea is that almost any ontology consists of several

298 sentences and that each sentence uses several non-logical symbols. The metaclasses in Basic_Model

299 package include Ontology_Whole, Ontology_Component and Ontology_Atomic_Construct, which have

300 administrative information of ontologies, sentences and non-logical symbols respectively. Since an ontology

301 evolves, Basic_Model package can register as many versions of an ontology as necessary. But, in

302 Basic_Model package, each version of an ontology is treated as a different ontology.

303 The Evolution_Model package is used to register information on how an ontology evolves from one version

304 to another. Evolution_Model package basically consists of three metaclasses, Registered_

305 Ontology_Whole_Evolution, Registered_Ontology_Component_Evolution and Registered_Ontology_

306 Atomic_Construct_Evolution, which have evolution information on Registered_Ontology_Whole,

307 Registered_Ontology_Component and Registered_Ontology_Atomic_Construct respectively.

313 Ontology_Whole is an abstract metaclass that represents an ontology and contains the associated

314 administrative information. Ontology_Language is used as the reference "modelType" of Ontology_Whole

315 to indicate a language that is used to express an ontology that is represented by Ontology_Whole.

316 Ontology_Component is an abstract metaclass that represents a sentence contained in ontologies and

317 contains the associated administrative information. The granularity of a sentence is not specified but is a

318 user’s choice. Ontology_Atomic_Construct is an abstract metaclass that represents a non-logical symbol

319 that is used in sentences and contains the associated administrative information.

320 Ontology_Whole has two direct subclasses, Registered_Ontology_Whole and Unregistered_Ontology_

321 Whole. Registered_Ontology_Whole is an abstract metaclass that represents an ontology that is registe
