Release of OME Files C++ 0.2.2

The OME Consortium are pleased to announce the release of OME Files C++ 0.2.2

Dear All,

Today we are releasing OME Files C++ 0.2.2.

OME Files is a reference implementation of the OME Data Model and OME-TIFF file format for the storage and interchange of biological imaging data and metadata. It provides support for:

  • The OME Data Model (model objects, metadatastore, XSL transforms and XML validation)
  • OME-TIFF reader
  • OME-TIFF writer

The major focus of this release is to extend the support for features in older OME-XML model versions and to improve the support for automated testing all OME-XML and OME-TIFF features. This will continue for the following release.

Major changes in this release include:

  • OME-TIFF reader and writer updates


The software release is available at

This page includes links to the individual repositories and source releases, as well as the documentation and binary builds of the collection for several common platforms, including Windows, Linux and MacOS X.

(note that this is a work in progress and subject to change).


Support for building on Windows with msbuild is currently non-functional; please use Ninja for the time being.

On Windows, "ome-files info" will display an error if run from a directory containing a space in it. As a workaround, use "libexecomefilesinfo.exe" directly.


For any problems or comments, please use the OME forums or mailing lists:

Kind regards, Roger Leigh
