VMAP is a vendor-neutral standard for CAE data storage to enhance interoperability in virtual engineering workflows.
As for now, the VMAP support in pyLife is in an experimental stage. That is mainly because there are not many other software packages available that do support it. Nevertheless we would like to encourage the usage of VMAP, so we decided to put the experimental code into the release.
pyLife supports a growing subset of the VMAP standard. That means that only features relevant for pyLife's addressed real life use cases are or will be implemented. Probably there are features missing, that are important for some valid use cases. In that case please file a feature request at https://github.com/boschresearch/pylife/issues
