Nick Burch commented on TIKA-560:
---------------------------------
The microsoft docs show the macro versions with a capital E, but Tika's
mimetypes.xml goes for the lower case. I'm minded to do the same from the
detector
> Improve detection of .mht, Foxmail, and OOXML files

> I would like to address the following issues
> 1. Reduce the priority of the text/html magics. WIth the default priority I
> have lots of .eml, .emlx, mbox and .mht files which contain html content but
> should not be classified as XML. The reason for that is that the HTML magic
> looks for <html> between 0 and 8192 offsets. In Aperture we solved this with
> an allowsWhiteSpace switch, so that the <html> can be prepended with
> whitespace but not with other content. Since there is no such switch in Tika,
> I suggest reducing the priority of the magic in tika-mimetypes. I attach an
> .mht file from the Aperture test document suite which exhibits the problem.
> 2. Add support for detecting Foxmail. They come from Foxmail, a mail client
> popular in china, they are roughly the same as mbox, but use a different
> separator.
> 3. In case of OOXML files, the container aware detector computes the mimetype
> by taking the part of [Content_Types.xml], namely:
> <Default Extension="bin"
> ContentType="application/vnd.ms-excel.sheet.binary.macroEnabled.main"/>
> then it takes the default content type and returns it with the part after the
> last dot removed. There are two issues with this approach
> a. some documents use macroEnabled, while other use macroenabled so the case
> is not standard
> b. the "official" mime types, contain a '12' suffix at the end, as shown at:
> http://technet.microsoft.com/en-us/library/ee309278%28office.12%29.aspx. I
> suggest to standardize on lowercase and add the '12' to the appropriate files.
