OME-XML is a vendor-neutral file format for biological image data, with an emphasis on metadata supporting light microscopy. It can be used as a data file format in its own right, or as a way of encoding metadata within a TIFF or BigTIFF file (for which purpose there is the OME-TIFF specification).
The standard is maintained by the Open Microscopy Environment Consortium, and was last updated in June 2012.
Bio-Formats reads proprietary microscopy image data and metadata, and converts them to OME-TIFF, a combination of TIFF and OME-XML.
Repository software for organising, viewing, analysing and sharing biological microscopy images. It supports proprietary file formats but normalises to OME-TIFF/OME-XML.
