ISO/IEC 11179-7:2019 情報技術—メタデータレジストリ（MDR）—パート7：データセット登録のメタモデル | ページ 6

3.1.1

access level

level of authority required from an entity to access a protected resource

Note 1 to entry: In the context of this document, items to which an access level may be specified are limited to a data set, a data set distribution and a data set collection.

Note 2 to entry: For the public, the level of authority might describe the degree of public availability of a dataset.

3.1.2

accrual periodicity

frequency with which items are added to a collection

Note 1 to entry: In the context of this document, it is assumed that an updated version of a data set is issued or made available whenever new items are added to that data set.

[SOURCE: ISO 2146:2010, 7.2.6, modified – Note 1 to entry added and EXAMPLE deleted]

3.1.3

data element collection

collection of data elements that may be unordered or ordered

Note 1 to entry: Examples of unordered collections are a set or a bag (or multiset). An example of an ordered collection is a list.

3.1.4

data set

dataset

identifiable collection of data available for access or download in one or more formats

Note 1 to entry: A data set can be a smaller grouping of data which, though limited by some constraint such as spatial extent or feature type, is located physically within a larger data set. Theoretically, a data set can be as small as a single feature or feature attribute contained within a larger data set.

Note 2 to entry: A data set may be presented in a tabular form and stored and distributed in tables in word processed documents, spread sheets or databases. It could also be presented in any one of a number of alternative formats, including AVRO, JSON, RDF and XML.

3.1.5

data set collection

curated collection of one or more data sets (3.1.4)

3.1.6

data set distribution

specific available form of a data set (3.1.4) or data set collection (3.1.5)

Note 1 to entry: Each data set might be available in different forms and each of these forms represents a different format of the data set or a different endpoint.

Note 2 to entry: Examples of distributions include a downloadable CSV file, an API or an RSS feed. This represents a general availability of a data set. It implies no information about the actual access method of the data, i.e. whether it is a direct download, API, or through accessing a Web page.

3.1.7

data set specification

additional formal information to describe a data set

Note 1 to entry: A data set specification may consist of zero, one or more ISO/IEC 11179-3Reference_Documents, zero, one or more ISO/IEC 19763-12Information_Models and/or zero, one or more sets of ISO/IEC 11179-3Data_Elements.

3.1.8

information model

graphical and textual representation of entities and the relationships between them

Note 1 to entry: An information model can exist as, at the conceptual or logical level, an entity relationship model or an object class diagram, and, at the physical level, a database schema definition.

3.1.9

ontology

specification of concrete or abstract things, and the relationships among them, in a prescribed domain of knowledge

Note 1 to entry: The specification should be computer processable, such as an ontology registered as metadata using the ISO/IEC 11179-3Concept Region specification.

3.1.10

provenance

information on the place and time of origin, derivation or generation of a resource or a record or proof of authenticity or of past ownership

3.1.11

rights

information regarding access or restrictions based on privacy, security or other policies

Note 1 to entry: This information may explain why a “non-public” or “restricted public” data set, data set distribution or data set collection is not “public”.

Note 2 to entry: This definition is derived from Project Open Data Metadata Schema v1.1 ( https://project-open-data.cio.gov/v1.1/schema/#dataQuality )

3.1.12

spatial coverage

geographical area which is the subject of a data set (3.1.4) or data set collection (3.1.5)

3.1.13

temporal coverage

period for which a data set (3.1.4) is applicable
