OME develops open-source software and data format standards for the storage and manipulation of biological microscopy data. It is a joint project between universities, research establishments, industry and the software development community., An OME-TIFF dataset consists of one or more files in standard TIFF or BigTIFF format, with the file extension .ome.tif or .ome.tiff, and an identical (or in the case of multiple files, nearly identical) string of OME-XML metadata embedded in the ImageDescription tag of each file's first IFD (Image File Directory). BigTIFF file extensions are also permitted, with the file extension .ome.tf2, .ome.tf8 or .ome.btf, but note these file extensions are an addition to the original specification, and software using an older version of the specification may not be able to handle these file extensions.
