2.6.2 商业流通领域数据字典(GS1 GDD)示例
GS1为了全球商业流通领域的电子数据交换，制定了商业流通领域全球数据字典(GS1 GDD)。GS1 GDD通用数据仓库(Common Library，CL)中存储了全球商业流通领域业务过程和信息交换使用的标准化的、可重用的类(Class)、业务属性(Business Attribute)、业务语境(Business Context)、数据类型、数据格式、约束条件(必备/可选)并提供了应用参考，包括XML schemas示例、EANCOM、核心组件(ebXML CC)以及包括全部产品信息编码标准的GS1通用规范，并对其实施动态维护。
GS1 GDD使用UML类图作为数据的结构设计，在GDD中定义了核心元数据的组成，构成了GS1全球商业流通领域核心元数据完整的描述和设计方法。
以核心贸易项目为例，核心贸易项目是贸易各方都涉及的最基本的数据，数据字典中核心贸易项目的内容包括:
(1)核心贸易项目高层级类图
核心贸易项目高层级类图如图2-8所示。
(2)核心贸易项目数据字典。
核心贸易项目数据字典见表2-5。

●类: ItemDescription
ItemDescription的属性包括: brandName、discriptionShort、itemName等。每一个属性都由语言代码和文本组成。文本语言使用ISO 639-1988两位字母代码，如英语是EN，法语是FR。
additionalAttributeDescription——自由文本，用来记录附加的产品属性。它可以用来标识信息提供者需要传送的任何附加信息。如制造商名称。additionalAttributeDescription是可选项。
brandName——品名。brandName是可选项。
descriptionShort——贸易项目的简要描述，descriptionShort是必备项。
itemDescription——信息提供者提供的产品描述。itemDescription是可选项。
itemName——比品名更完全的产品名称。itemName是可选项。
●类: Classification
贸易项目的Classification是必备项，根据需要可重复。Classification包括以下属性:
classificationAgency——classificationAgency是负责管理和维护产品分类代码的团体，例如UN/SPSC、CPC等。classificationAgency是必备项。
●类: PartyIdentification
全球贸易参与方位置代码(GlobalLocationNumber，GLN)或者使用AlternatePartyIdentification来标识一个贸易参与方。每个参与方仅能使用一个参与方标识符。
●类: GlobalLocationNumber
G lobalLocationNum ber(GLN)是一个13位数字代码，用于唯一标识贸易参与方的位置。包括:
——EAN.UCC厂商识别代码。
——位置参考。
——校验位。GLN是用来标识一个法律实体的机构或组织的代码，即对贸易参与方的标识，如:
合法实体:批发公司、附属机构或部门，如供应商、零售商、客户、银行和转运商等。
功能实体:在合法实体内具体的部门，如会计部门、销售部门和客户编号等。
物理实体:在建筑物、仓库、仓库门、装运码头、交付点、箱体、住宅线路板、建筑物内的房间等。
gln——一个具体的GlobalLocationNumber。gln是必备项。
●类: GlobalTradeItemNumber
GlobalTradeItemNumber是主要的贸易项目标识符。如果产品申请了GlobalTradeItem Number(GTIN)代码，就必须使用它来标识产品。而且仅能使用一个标识代码。GTIN包括UCC-12、EAN.UCC-8、EAN.UCC-13和EAN.UCC-14。
gtin——一个具体的GlobalTradeItemNumber。gtin是必备项。
