Are there naming rules in Arxml?

I am checking the ‘IPdu Mapping’ in AUTOSAR_TPS_SystemTemplate.pdf, IPduMapping in Arxml will be I-PDU-MAPPING，targetIPdu will be TARGET-I-PDU, is there any rules on the name?

Any AUTOSAR document mention this naming convention?

<I-PDU-MAPPINGS>
  <I-PDU-MAPPING>
    <SOURCE-I-PDU-REF DEST="PDU-TRIGGERING">/Cluster/CAN/xxxx</SOURCE-I-PDU-REF>
    <TARGET-I-PDU>
      <TARGET-I-PDU-REF DEST="PDU-TRIGGERING">/Cluster/CAN/xxxx</TARGET-I-PDU-REF>
    </TARGET-I-PDU>
  </I-PDU-MAPPING>
</I-PDU-MAPPINGS>
Solution

  • You will find the answer to your question in chapter 3.6 (named "XML Names") of the AUTOSAR standard document "TPS SchemaProductionRules".

    In short, capital letters in the name of a meta-model element (like IPduMapping) trigger the existence of a "-" in the XML name in the schema (translating it to I-PDU-MAPPING). XML names in the AUTOSAR schema are all-uppercase by convention. There are further rules for numerals, as described in the quoted chapter.
