Resolution: Accept. Status: closed

Templates for the following capabilities must be harmonized:
C076: assigning_product_properties
C077: assigning_process_properties
C078: assigning_resource_properties
C080: representing_properties_textually
C079: representing_properties_numerically
C084: representing_property_value_ranges
C056: representing_evolution_of_property_values.
If possible, the document property capability C087: assigning_document_properties should also be harmonized with other properties.
In order to minimize the number of total templates for properties, the following structures of templates has been proposed:
1. assignment of the property (product, process, or resource)
2. association of a representation with an assigned property (i.e. associate a text property with a product property)
3. representation of a value (text, numerical, or a numerical range)
Number 1 and 2 above would exist in three different 'flavours', for products, processes (activities) and resources. Number 3 would be generic, and applicable to all.
If the current division of properties would be used, as in the capability C079: representing_properties_numerically where number 2 and 3 above are collapsed in one template, we would need agreat number of templates to represent all different types of numerical ranges in C084: representing_property_value_ranges, and we would not re-use the value representations at all.
See templates in capability C080: representing_properties_textually for an example of the propsed solution.

This harmonization has been carried out.
