This document describes the general structure of the "ShoeML" framework of data formats for the business documents containing "footwear design data". The new data formats have been designed and implemented as a set of XML Schemas. The document describes the coverage of the data formats, their capabilities and internal details, the built-in validation rules about their content, and lists the main intended usages. Annex A1 and Annex A2 actually contain the latest version of the ShoeML Schemas, together with short descriptions, with the scope to drive the software implementation. Technical details about the Geometry subschemas, actually the most complex ones, are contained in Annex A3. The proposal is complemented by two documents intended as "guidelines" or "best practices" about the following aspects: - Footwear Measurements - Footwear Design Terms They cover several aspects of design on which consensus was impossible to find, and are intended as initial efforts to make the experts in the field converge. In the following paragraphs a high-level description of the ShoeML data format is attempted. The format, as you will see, is made of simple and complex parts. The core of the proposal can be considered quite stable (BasicGeometry, Design, DesignPart, DesignGroup, Picture ), but many "extensions" will be needed to cover fully the needs of the sector. During the project this "extension process" was started by defining 4 extension schemas covering the "CAM interfacing" part, namely the exchange of business data between "pure design" activities and "production". This process is far from being complete, but the proposal contains the general structure of the extension mechanism, that will be used in the future as a guide to complete the coverage. "Extensibility" is indeed the "secret weapon" of the proposal. Built in into XML itself, the capability of "extending" the formats to suit specific needs is the key to the widespread adoption of the new proposal in the complex field of "footwear design and production". While working on the project we already had the occasion to meet requirements, actually coming from footwear CAM industries, to split "design" data into a "public" one and a "machine dependent" one. Protection of information considered "sensible" by the industry has always been the main reason behind the usage of "custom" and "undocumented" formats, actually generating the conversion mess we are accustomed to. In the past there was no choice: either completely "open" and "conformant" to a standard, or completely "closed". The new approach, actually part of this proposal, is to adopt a highly modular data format with extensibility mechanisms built-in, allowing each industry to actually split data into "public" and "custom" (or protected) parts. This simple "extension" mechanism will allow recovery and simple reuse of the public parts, which are often the most valuable ones. Recovering geometry data, for instance, will allow to adapt a particular building operation from a specific machine to another, thus preserving the industry's investments in the long period.
