The newly created convention is now ready for use, but you probably want to specify some additional attributes. To modify the attributes of the newly created convention:

  • Press <Enter> or double click on the convention.

The most commonly used attributes of a convention are discussed below.

  • PER QUANTITY : The PER QUANTITY attribute should be used to override the unit of all identifiers that express a value of a particular quantity. For example, if the PER QUANTITY attribute contains a line 'SI_LENGTH : inch ‘, all identifiers that are expressing a length (and were expressed in terms of [m] , [cm] , [mile] , etc.), will be expressed in [inch] .

  • PER UNIT : The PER UNIT attribute should be used to override the unit of all identifiers that share a particular UNIT attribute. For example, if the PER UNIT attribute contains a line ‘m : cm ‘, all identifiers that are originally measured in [m] will be expressed in [cm] , and all identifiers that are originally measured in [m/s] are expressed in [cm/s] etc.

  • PER IDENTIFIER : The PER IDENTIFIER attribute should be used to override the unit of a particular identifier. By applying the convention. For example, if the PER IDENTIFIER attribute contains a line ‘Size : m ‘, the identifier ‘Size ‘ will be expressed in terms of [m] (assumed that its original UNIT attribute was commensurate with [m] ).
