Open Mining Format (OMF 1.0.1)

API library for Open Mining Format, a new standard for mining data backed by the Global Mining Guidelines Group.


An open-source serialization format and API library to support data interchange across the entire mining community.


This library provides an abstracted object-based interface to the underlying OMF serialization format, which enables rapid development of the interface while allowing for future changes under the hood.


  • The goal of Open Mining Format is to standardize data formats across the mining community and promote collaboration
  • The goal of the API library is to provide a well-documented, object-based interface for serializing OMF files


OMF is intended to supplement the many alternative closed-source file formats used in the mining community.


OMF 1.0 supports basic structures including points, lines, surfaces, meshes, and volumes. It is the outcome of the Data Exchange for Mine Software project under the GMG Data Access and Usage/Interoperability Working Group
