Group to list description elements that define part classes and part group names used within a package description. This element is optional.

Example:

<package>

/package/part-taxonomy/description

This element describes a part class or the combination between a part class and a part group. Parts are categorized by Hclass and Hgroup. The creator of a package can define names for Hclass and Hgroup. Thus, configuration tools can display the set of available parts. A document can be referenced using the attribute doc. The attribute generator can be used to reference to a generator tool. The id of the generator needs to be the same as specified in the element /package/generators/generator. The description itself is a string entered between the opening and closing tags of the element description.

It is recommended to use an already agreed part-taxonomy for interchangeable parts.

Example:

<part-taxonomy>
  <description Hclass="Audio ICs">Audio Amplifiers, Audio Processors, MEMS Microphones, Sound Terminal Digital Audio Subsystem</description>
  <description Hclass="Automotive" Hgroup="Logic ICs">Buffers/Drivers, Counters/Encoders/Decoders, FlipFlop/registers, Gates, ...</description>
</part-taxonomy>

Note

You must not use Windows or Linux reserved characters for Hclass, Hgroup, and Hsub names! Reserved characters are:

< (less than)
> (greater than)
: (colon)
" (double quote)
/ (forward slash)
\ (backslash)
| (vertical bar or pipe)
? (question mark)
* (asterisk)

Attributes	Description	Type	Use
Hclass	Part Class Name. Can be defined by the creator of the package. Predefined values can be used as listed in the table Part Classes.	HclassType	required
Hgroup	Part Group Name. Can be defined by the creator of the package. Predefined values can be used as listed in the table Part Groups.	HgroupType	optional
doc	Reference to documentation.	xs:string	optional
generator	Reference to a generator. Enter the id value of the element /package/generators/generator.	xs:string	optional
public	Set publishing permissions for the documentation. If <public> is true, then the vendor gives permission to extract the documentation from the pack and publish it on a web-page. Links to web pages are assumed to be public. The default value is true (this is also the basic assumption if the tag is missing).	xs:boolean	optional

Table: Part Classes and Groups

Part Class and Part Group names are strings with a minimum length of 3 characters and a maximum length of 32 characters. Part Class and Part Group names are specified in the section /package/part-taxonomy/description. Part Group names are specified by the element Hgroup and create categories within a Part Class specified by the element Hclass.

Part Classes and Part Groups can be used in the elements:

Example:

<... Hclass="MEMS and Sensors" Hgroup="MEMS Microphone" ...>

The following table lists predefined Part Classes. Within each Part Class, some Part Groups have been also defined.
