The work of preparing
11、International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaiso
12、n with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of tec
13、hnical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is dra
14、wn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 19131 was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics. BS ISO 19131:2007 License
15、d Copy: London South Bank University, London South Bank University, Wed May 16 03:44:56 GMT+00:00 2007, Uncontrolled Copy, (c) BSI v Introduction A data product specification is a detailed description of a dataset or dataset series together with additional information that will enable it to be creat
16、ed, supplied to and used by another party. It is a precise technical description of the data product in terms of the requirements that it will or may fulfil. However, the data product specification only defines how the dataset should be. For various reasons, compromises may need to be made in the im
17、plementation. The metadata associated with the product dataset should reflect how the product dataset actually is. A data product specification may be created and used on different occasions, by different parties and for different reasons. It may, for example, be used for the original process of col
18、lecting data as well as for products derived from already existing data. It may be created by producers to specify their product or by users to state their requirements. The purpose of this International Standard is to provide practical help in the creation of data product specifications, in conform
19、ance with other existing standards for geographic information. An aim is to produce a complete list of the items used to specify a data product. This International Standard makes references to parts of existing standards. Some of the items used to specify the data in a data product can also be used
20、as metadata for a resulting dataset with the same data product. It is not necessary for a data product specification to specify the production process, but only the resulting data product. Nevertheless, it may include production and maintenance aspects if judged necessary to describe the data produc
21、t. This International Standard describes the content and structure of a data product specification. An example of a data product specification is presented in Annex F. When an item for a data product specification is already defined in another standard of the ISO 19100 series, a reference to that do
22、cument is explicitly made. This International Standard is intended for use by producers, providers and potential users of data products.

24、based upon the concepts of other ISO 19100 International Standards. It also provides help in the creation of data product specifications, so that they are easily understood and fit for their intended purpose. 2 Conformance Any data product specification claiming conformance with this International S

30、er requirements ISO 19101 4.2 application schema conceptual schema for data required by one or more applications ISO 19101 4.3 conceptual model model that defines concepts of a universe of discourse ISO 19101 4.4 conceptual schema formal description of a conceptual model ISO 19101 4.5 coverage featu
31、re that acts as a function to return values from its range for any direct position within its spatial, temporal or spatiotemporal domain ISO 19123 EXAMPLES Raster image, polygon overlay, digital elevation matrix. 4.6 data product dataset or dataset series that conforms to a data product specificatio
32、n 4.7 data product specification detailed description of a dataset or dataset series together with additional information that will enable it to be created, supplied to and used by another party NOTE A data product specification provides a description of the universe of discourse and a specification
33、 for mapping the universe of discourse to a dataset. It may be used for production, sales, end-use or other purposes. 4.8 dataset identifiable collection of data ISO 19115 NOTE A dataset may be a smaller grouping of data which, though limited by some constraint such as spatial extent or feature type
34、, is located physically within a larger dataset. Theoretically, a dataset may be as small as a single feature or feature attribute contained within a larger dataset. A hardcopy map or chart may be considered a dataset. BS ISO 19131:2007 Licensed Copy: London South Bank University, London South Bank

36、ing that satisfies the definition is in the set and everything that does not satisfy the definition is necessarily outside the set. 4.11 feature abstraction of real-world phenomena ISO 19101 NOTE A feature may occur as a type or an instance. Feature type or feature instance shall be used when only o
37、ne is meant. 4.12 feature association relationship that links instances of one feature type with instances of the same or a different feature type ISO 19110 NOTE 1 A feature association may occur as a type or an instance. Feature association type or feature association instance is used when only one
38、 is meant. NOTE 2 Feature associations include aggregation of features. 4.13 feature attribute characteristic of a feature ISO 19101 NOTE 1 A feature attribute may occur as a type or an instance. Feature attribute type or feature attribute instance is used when only one is meant. NOTE 2 A feature at
39、tribute type has a name, a data type and a domain associated with it. A feature attribute for a feature instance has an attribute value taken from the domain. 4.14 geographic data data with implicit or explicit reference to a location relative to the Earth ISO 19109 NOTE Geographic information is al
40、so used as a term for information concerning phenomena implicitly or explicitly associated with a location relative to the Earth.

45、t in relation to the source object. Thus, in a two-way association, two role names will be supplied. Figure 2 represents how role names and cardinalities are expressed in UML diagrams.

It is a model element that is used to classif
47、y (or mark) other UML elements so that they behave in some respect as if they were instances of new virtual or pseudo metamodel classes whose form is based on existing base metamodel classes. Stereotypes augment the classification mechanisms on the basis of the built-in UML metamodel class hierarchy
48、. Below are brief descriptions of the stereotypes used in this International Standard. For more detailed descriptions consult ISO/TS 19103. In this International Standard the following stereotype is used: package that contains definitions, without any sub-packages. 5.5 Package abbreviations Abbrevia
49、tions are used to denote the package that contains a class. Those abbreviations precede class names, connected by a “_”. The International Standard in which those classes are located is indicated in parentheses. A list of those abbreviations follows.
