2. |  | General
3.0. |  | Terminology
This section defines the basic terminology used in the QDX specification. Quality data is a set of required data that is transferred from the sending company to the receiving company. This data is independent from a specific format. A quality data document is an XML file that contains the relevant quality data stored in the QDX format; this document / file is transferred to the receiver.
2.2. |  | Structure of the specification / documentation
The documentation of the QDX V1.0 standard consists of a set of different documents. This document at hand is the detailed specification of the standard. It is complemented by the formal specification in the form of XSD files (XML Schema) as well as examples of QDX-compliant XML files. The following section describes the structure of the specification. This documentation has been generated as 'compiled html file (.chm)'. Section one and two represent the introduction and this general explanation. Section 3 contains a hierarchical view to a specific message (example: QDXComplaint) beginning with the root element. On the left hand side, status and occurrence )miOccurs and maxOccurs are shown. The hierarchy does not show attributes. The element tags are hyperlinked with the detailed description of all elements and attributes as shown in section 4.
Section 4 contains the details for every element and attribute. On the left hand side the message tree is shown and the nodes of complex elements can opened to see the details inside. On the right hand side all relevant information concerning the selected node / object are shown.
The data type tag in section 4 is hyperlinked with section 5, which describes the complex and simple data types the elements and attributes are based on.
In the components report, a graphic shows the element and the related child elements or attributes. The element names of contained elements are hyperlinked again with their data types, the usage reference is hyperlinked with section 4 – detailed message structure. The symbols used in the diagram have the following meaning:
xsd:sequence – the elements in the XML instance file must follow exactly the described sequence. Optional elements (Status 0) or attributes (use = optional) may be omitted. Mandatory elements must occur in the structure. xsd:choice – one (and only one) of the sub-elements may occur in the XML instance file (XOR relation).
2.3. |  | Coding in XML
The coding of individual characters in the XML elements should be specified in each XML file. This is done in the attribute "encoding" of the XML text declaration as in <?xml version="1.0" encoding="UTF-8">. Here "UTF-8" is specified as a character set. QDX supports all the character sets which appear in the XML specification (for example, ISO-8859-1, UTF-8, UTF-16). With UTF character sets, a character is normally stored in one or more bytes. Field lengths are not specified in this specification. They must be agreed upon bilateral between the business partners if necessary.
2.4. |  | XML Schema Files (XSD)
XSD files have been generated according to UN/CEFACT's ATG2 name and design rules (ATG - Applied Technologies Group).
The root folder is qdx-xsd, which contains sub-folders as follows: + jai/common Re-usable components from the Joint Automotive Industry project + jai_qdx/common Re-usable components from the QDX project + jai:qdx/maindoc Message schemas for the individual messages (QDXCertificate , QDXComplaint ... ) - the XML instances may be validated against the appropriate schema file. + jai_qdxcom/common Basic components of the QDX project + standard/common standardized data types for code lists (enumeration types). The namespace prefixes have been generated automatically. They may be replaced by shorter prefixes in the XML instance files, provided, a correct assignment between namespace prefix and namespace URI is ensured.
