7z file format is missing mime type

Open pwinckles opened this issue 1 year ago • 2 comments

In the v116 sig file, the 7z format is defined as follows:

        <FileFormat ID="1271" Name="7Zip format" PUID="fmt/484">
            <InternalSignatureID>756</InternalSignatureID>
            <Extension>7z</Extension>
        </FileFormat>

The definition is missing the attribute MIMEType="application/x-7z-compressed".

@pwinckles the mimetype for 7z doesn't seem to have been recorded in PRONOM yet:

This might be an issue for the PRONOM research repo. A number of folks suggest changes such as this for the underlying data there:
