IEEE 1671.3:2007 pdf free download – IEEE Trial-Use Standard for Automatic TestMarkup Language (ATML) for Exchanging Automatic Test Information via eXtensible Markup Language (XML)
1.1 Scope
The scope of this trial-use standard is the definition of an exchange format，using eXtensible MarkupLanguage (XML),for information that uniquely describes a category or type of UUT. The format willinclude the ability to specify multiple manufacturers for each UUT, as casces may exist where a single UUTis supplied by a variety of manufacturers. This information is intended to support all aspects of the test andmaintenance environment.
1.2 Purpose
The purpose of this trial-use standard is to promote and facilitate interoperability between components oftest and maintenance support systems by defining a common set of identification information for UUTs.The UUTDescription schema becomes a class of information that can be used within the ATML family ofstandards. This standard will allow a common UUT description to be transportable across a variety of testand maintenance environments, including but not limited to, the automotive, semiconductor, acrospace, andmilitary industries.
1.3 Application
This trial-use standard providcs for the identification of static characteristics of either a hardware or asoftware UUT. Characteristics are descriptive attributes relating to a UUT’s form, fit, and function. Thiscollection of characteristics defines either a class or type of uUT (as represented by theUUTDescription.xsd schema defined in Clause 4) or a specific UUT (as represented by theUUTInstance.xsd schema defined in Clause 5). Either collection of characteristics may be used for thepurposes of developing test fixtures (holding andor interface devices),interfacing (such as electricalcabling or optical interfaces), or defining a test configuration
All simple types, complex types, attribute groups, and elements will be listed; explanatory information willbe provided, along with examples if additional clarification is needed.The explanatory information willinclude information on the intended use of the elements andor attributes where the name of the entity doesnot clearly indicate its intended use.For elements derived from another source type(e.g., an abstract type),only attributes that extend the source type will be listed; details regarding the base type will be listed alongwith the base type.
When referring to an attribute of an XML element, the convention of [element]@[attribute] will be used.ln cases where an attribute name is referred to with no associated element, the attribute name will beenclosed in single quotes. Element and type names will always be set in italics when appearing in text.
This trial-use standard uses the vocabulary and definitions of relevant IEEE standards. In case of conflict ofdefinitions, except for those portions quoted from standards, the following precedence shall be observed:(1) Clause 3,(2)Annex C, and (3) The Authoritative Dictionary of IEEE Standards Terms [B2].
4.5 Inherited simple types
Within the w3C XML schema hierarchy, all types derive from the root type anyType.The first branchwithin this hierarchy is into two groups: simple types and complex types. A simple type provides a nameunique within a schema for one of the base XML datatypes and may not have child elements. Optionally,constraints may be imposed to limit the content of elements derived from the simple type.
Within the UUTDescription schema，all simple types shall be inherited from the imported schemasCommon.xsd and HardwareCommon.xsd defined in Annex B of IEEE Std 1671.
4.6 Inherited complex types
The second major branch of the W3C XML schema hierarchy is the “complex type.””An XML complextype may derive from one of the W3C XML base types or from a schema-defined simple type.Unlike asimple type, a complex type may have subordinate child elements along with restrictions or extensions ofthe inherited base type. The hierarchical nature of XML schema likewise permits the child elements of acomplex type to also be complex types.
Within the UUTDescription schema,all complex types shall be inherited from the imported schemasCommon.xsd and HardwareCommon.xsd defined in Annex B of IEEE Std 1671.
