ecospold1 Schema Updates

1.1

This library includes a new version of the schema definitions for ecospold1. Version 1.1 includes the following changes:

• Changed the length restriction on referenceFunction.name to 255
• Changed the length restriction on referenceFunction.synonym to 255
• Changed the length restriction on category and subCategory to 255
• Changed the length restriction on representativeness.productionVolume to 32.000
• Made telephone optional

These changes were based on how this schema was being used by LCA software.

1.2

Corrected the handling of CAS numbers based on the official documentation:

• A fixed size isn't required, zero-padding is optional and in any case is not used consistently by LCA software
• Maximum length is 12, not 11
• The first element has a minimum size of 2 digits, not 1
