viThe following list is gathering all mime-types that are listed in various interoperability projects and standard protocols.

Row Color Coding

The red labelled rows are proprietary formats that should be avoided

The green labelled rows are preferred formats for IVOA tools (that we use in VESPA). 

The white labelled rows are formats to be assessed during the VESPA project

application/x-geotiffgeotiff.tif, .tiffGeoTIFF is a public domain metadata standard which allows georeferencing information to be embedded within a TIFF file. The potential additional information includes map projection, coordinate systems, ellipsoids, datums, and everything else necessary to establish the exact spatial reference for the file. The GeoTIFF format is fully compliant with TIFF 6.0, so software incapable of reading and interpreting the specialized metadata will still be able to open a GeoTIFF format file.ogc

    What does Data Model refer to?

    1. Baptiste Cecconi

      this is the data model in which the format was found (typically as an allowed value for a "data format" keyword). When it was not found, I put epncore by default, by we may only keep encore for those we have made a decision on.

  2. Mikhail Minin

    What MIME type to use for WMS? Is it ok to use multiple, separated by a coma, e.g.
    "image/tiff, image/png"?

    1. Stéphane Erard

      In the reference list linked above, there is a mention of

      application/x-wms

      which should do. The syntax for lists is image/tiff#image/png (separator is #, with no extra space or quotes), but this should not be applicable to product types: you're expected to provide only one product / granule.

    What type for spice kernels? - required to handle dynAstVO outputs.
