FML File Format Specification

Welcome to the FML (Floorplan Markup Language) file specification, a standard format for storing detailed information about floor plans. This specification utilizes JSON (JavaScript Object Notation) to describe the structure of a floor plan, including the layout of rooms, walls, doors, and other features.

This format is designed to be easy to read and understand, while also providing a wide range of flexibility for different types of floor plans. Whether you're an architect, building designer, or just need to plan out the layout of a space, this specification will help you organize and communicate your ideas effectively.

Benefits

FML is format well suited for describing floorplans in a simple way with resource constraint requirements.

  • The use of JSON as the file format makes it easy to read and understand, as well as widely supported by a variety of programming languages and tools.

  • It allows for easy communication between different parties involved in a building project, such as architects, contractors, and engineers, as they can all use the same format to share and understand floor plan information.

  • The specification provides a standardized way of organizing and describing floor plan information, which can reduce errors and misunderstandings that can occur when using different, incompatible formats.

  • It allows for easy integration with other software and tools, such as building management systems, architectural visualization software, and BIM (Building Information Modelling) systems.

  • The flexibility of the format allows it to be used for a wide range of building types and sizes, from small residential renovations to large commercial and industrial projects.

  • It can also be used to automate certain tasks, such as cost estimation, building energy analysis and even generate 3D models.

Missing features

  • Roofs and roof configurations are currently not supported in the specifications.

  • Hedges and garden specific features are not yet specified.

  • Eletric wiring and plumbing are not specified yet.

History
