MacroMolecular Transmission Format MMTF

Allows to transmit and store biomolecular structures for fast 3D visualization and analysis. MMTF reduces bandwidth needs and allows in memory management of large structure. It can be parsed, in some instances at least an order of magnitude faster than existing text-based formats. The format is designed for interoperability and use by a broad community. It enables fast transfer, parsing, and low client side overhead for high-performance visualization in web-based viewers and in particular mobile devices.
