GLDF files describe single products and
Variants thereof. That said, even though you define a single product in a GLDF file, every product consists of at least one
Variant, but there is no limit to the number of
Variants of a single product you can add to a GLDF file.
For this reason, we divided the GLDF product definitions into two parts. The first part is the
ProductMetaData. Anything defined here will apply to all variants in the GLDF file.
If a property is present in
- it applies to all variants in the gldf file
- properties can be overwritten or enhanced by the variants
This convention always prevails without having to be explicitly defined.
Let's assume you have a standing luminaire in your product portfolio with different electrical components for other markets. You can apply all the same pictures, names, descriptions, etc., to all variants but define separate electrical properties in the electrical section of the descriptive attributes.
You have a track-mounted luminaire that comes with different reflectors. All Luminaires will have the same name, descriptive attributes, etc. However, the 3D Model and the Light distribution would change for the other variants.
