The Lexicon Module supports PropertSheet Analysis in the ERP5 implementation process.
Lexixons are either based on document analysis and Use Cases related to a given module. A useful lexicon should identify any properties defined in a document item or in a Use Case and map them to existing propertysheet or class in ERP5. Some properties may be stored, others calculated dynamicaly.
Very often, properties defined by ERP5 PropertySheets are quite generic use names completely different with the names which are used for management in an industry or activity. For example, the property quantity is used to store debit and credit values in accounting.
The main interest of Lexicons is to force a team to define all names which are then manipulated by ERP5 and to accelerate the mapping of such names to the existing ERP5 framework through a review workflow on Lexicons.
