13、BS ISO 15143-2:2010ISO 15143-2:2010(E) iv ISO 2010 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO techni
14、cal 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 liaison with ISO, also take part in the work. ISO collaborates closely w
15、ith 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 technical committees is to prepare International Standards. Draft Int
16、ernational 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 drawn to the possibility that some of the elements of this document m
17、ay be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15143-2 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee SC 3, Machine characteristics, electrical and electronic systems, operation and mainte
18、nance. ISO 15143 consists of the following parts, under the general title Earth-moving machinery and mobile road construction machinery Worksite data exchange: Part 1: System architecture Part 2: Data dictionary BS ISO 15143-2:2010ISO 15143-2:2010(E) ISO 2010 All rights reserved vIntroduction Electr
19、onic data exchange on the construction worksite is rapidly becoming a key technology enabling a number of advances in the construction industry. Moving from predominantly manual data collection methods to more automated data collection and communication will improve worksite quality control. Electro
20、nic data exchange will further aid in the scheduling of maintenance, the provision of supervisory functions to be conducted remotely from the worksite and the enhancement of the coordination between engineering tasks, construction management and day-to-day operations on the worksite. The implementat
21、ion of an electronic data communication system requires an a-priori definition and specification of the elements of data to be communicated. Specification of unique data elements for worksite communication involves the use of an application schema to diagrammatically identify the scenario in which e
22、ach item of data is to be used. After the scenario has been described, data elements are assigned metadata attributes to fully define and describe the individual data element. The list of data elements with attributes are compiled in tabular form in a data dictionary, which forms the subject of this
23、 part of ISO 15143. Generally, the purpose of data dictionaries is recognized to be the following: a) to improve the ability to share data elements in a particular domain or among different domains; b) to provide a base for better understanding of the semantic meaning and syntax of data elements; c)
24、 to manage a data resource so as to maintain the correctness and consistency of the resource; d) to provide a basis for the development of consistent databases and software that use databases.

25、ed 1Earth-moving machinery and mobile road construction machinery Worksite data exchange Part 2: Data dictionary 1 Scope This part of ISO 15143 specifies a data dictionary for the exchange of data in worksite data-controlled construction operations as specified in ISO 15143-1. It also applies to wor
26、ksite data exchange for the purpose of services related to machine use (see ISO 15143-1:2010, Clause 4), and gives definitions of terms used in relation to the data dictionary. For the purposes of data exchange between different systems, it includes identification, definition and specification of co
27、mmon items of data to be exchanged on typical earth-moving construction worksites, definition of application schema, metadata describing the attributes of each data element, and basic normative data elements with their attributes (in tabular format). NOTE ISO 15143-1:2010, Annex A, describes the mea
28、ns to extend the data element table presented in Annex A of this part of ISO 15143. 2 Normative references The following referenced documents are indispensable for the application of this document.
