# TopometrixReader

This page lists supported metadata fields for the Bio-Formats TopoMetrix format reader.

These fields are from the OME data model. Bio-Formats standardizes each format’s original metadata to and from the OME data model so that you can work with a particular piece of metadata (e.g. physical width of the image in microns) in a format-independent way.

Of the 476 fields documented in the metadata summary table:

  - The file format itself supports 22 of them (4%).

  - Of those, Bio-Formats fully or partially converts 22 (100%).
