Steve Shanbaum Posted September 7, 2022 Report Share Posted September 7, 2022 Please find attached the 0.88 draft version of the Lens Product Description Standard. The flexible nature of this standard will allow for a single catalog format that both lens blank manufacturers and freeform lens designers are able to use. In the not-too-distant future, it can also serve as a catalog for optical laboratories to describe their lens offering, though that's not the focus of this initial release. Due to the flexibility of the standard, I'm going to add a little expository text here that will hopefully help describe the very high-level usage of the standard. Capitalized words indicate their related objects within the standard. When a blank manufacturer provides a new catalog, they will be including a number of Blanks, which share common features (to reduce duplication) that are grouped by a Blank Collection. It's at the Blank Collection level that characteristics that are common across a large selection of Blanks are stored, such as a shared Material and Design. These Blank Collections are referenced by a Product. Though it may appear that the Product represents needless duplication of the Blank Collection, it enables the use of the standard by lens designers as well. Lens designers will be able to describe a Product, referencing a particular Design that can be applied to a range of Materials, without having to specify the actual Blanks to which the Design can be applied. The consumer of the Standard will be able to know the specifications of that Design, and to which range of lenses it can be applied. Looking down the road, this is the same flexibility that will allow the Standard to be used by a lab to electronically provide a catalog to a retailer, in that the lab can use the Standard to define a set of Products that are orderable, along with the relevant constraints on those products, such as the inclusion or exclusion of particular treatments. This does mean that the way the Standard will be parsed may differ depending on the consumer. An optical lab that is importing technical specifications for a new set of lens blanks will focus on starting from the included Blank Collections. A retailer will be more concerned with what can be ordered from the Product side, and will start the import there. As this is still a draft version, we are looking forward to your feedback on improving the Standard's usability and coverage. Please feel free to comment here with your thoughts after giving the standard a read. As an aside, I would like to thank all the members of the editorial committee over the years (and those who might not be officially on it, but have sure spent time in the meetings at some point). It's truly been a team effort to bring this document to the level that it's at, and I appreciate your time hashing through the topics at our numerous meetings and creating samples and diagrams.
