Andrew Jackson commented on TIKA-1486:
--------------------------------------
There's no problem with adding an XML namespace in principle - I'm not using a
MIME-info specific parser or anything. It's just that because the namespace is
not declared, the document is not
[namespace-well-formed|http://stackoverflow.com/questions/14871752/is-xml-document-with-undeclared-prefix-well-formed],
and this upsets some parsers. It's not critical - it just makes it harder to
parse the document with an off-the-shelve XML parser configuration.
On the globs, is there a functional difference between the "^rdf$" and "rdf"
globs? If not, I'll just configure my analyser to strip out the ^ and $.

> Key: TIKA-1486
> URL: https://issues.apache.org/jira/browse/TIKA-1486
> Project: Tika
> Issue Type: Improvement
> Components: detector
> Affects Versions: 1.6
> Reporter: Andrew Jackson
> Priority: Minor
>
> I've started running some routine tests on format information held in a
> number of tools, including
> [Tika|http://www.digipres.org/formats/sources/tika/issues/]. This uncovered a
> number of minor issues when working with the tika-mimetypes.xml file:
> * Duplicate MIME type application/gzip-compressed for type application/gzip.
> * Duplicate MIME type image/vnd.dwg for type image/vnd.dwg.
> * Error when parsing XML: Namespace prefix tika on link is not defined, line
> 169, column 15
> * Format application/dita+xml;format=task has itself as a supertype!
> * Glob '^owl$' for entry application/rdf+xml does not appear to be a valid
> filename specification.
> * Glob '^rdf$' for entry application/rdf+xml does not appear to be a valid
> filename specification.
> With the last two, it's really a matter of consistency. The other
> full-filename globs do *not* use the ^ and $ start and end markers, but owl
> and rdf do.
