> Detecting problem with Matlab source code
> -----------------------------------------
>
> Key: TIKA-1634
> URL: https://issues.apache.org/jira/browse/TIKA-1634
> Project: Tika
> Issue Type: Improvement
> Components: mime
> Affects Versions: 1.8
> Reporter: Ji-Hyun Oh
> Assignee: Chris A. Mattmann
> Priority: Trivial
> Labels: earthcube
> Fix For: 1.9
>
> Attachments: BARCAST_MainCode.m, Initial_Vals_Maker.m, custom-mimetypes.xml,
tika-mimetypes.xml, wtsgaus.m
>
>
> Both Matlab source code and Objective-C source code have the same suffix, which is .m.
Therefore, Matlab has additional match value in mime types.xml.
> In tika-mimetypes.xml Matlab is defined as:
> <mime-type type="text/x-matlab">
> <_comment>Matlab source code</_comment>
> <magic priority="50">
> <match value="function [" type="string" offset="0"/>
> </magic>
> <!-- <glob pattern="*.m"/> - conflicts with text/x-objcsrc -->
> <sub-class-of type="text/plain"/>
> </mime-type>
> However, Matlab codes does not always start with "function [“. Therefore, some Matlab
codes are detected as text/x-bojcsrc. Based on the source codes collected from NOAA Paleoclimatology
Software Resources, many Matlab codes have match value like these (problematic files are attached
as an example):
> <mime-type type="text/x-matlab">
> <_comment>Matlab source code</_comment>
> <magic priority="50">
> <match value="function" type="string" offset="0"/>
> <match value="%" type="string" offset="0"/>
> </magic>
> <!-- <glob pattern="*.m"/> - conflicts with text/x-objcsrc -->
> <sub-class-of type="text/plain"/>
> </mime-type>
> Conducted several detecting tests by using different Matlab packages obtained from NOAA
Paleoclimatology Software Resources, with/without Custom-mimtypes.xml. Results are attached.
As a results, total 103 Matlab files are detected correctly with custom-mimetypes.xml, while
42 Matlab files are detected as Matlab files without custom-mimetypes.xml (= only with current
match value). However, this match value for Matlab source code could be only common in Paleoclimatology
community.
