> Key: TIKA-2422
> URL: https://issues.apache.org/jira/browse/TIKA-2422
> Project: Tika
> Issue Type: Improvement
> Components: detector, mime
> Reporter: Sebastian Nagel
> Priority: Minor
> Fix For: 1.16
>
>
> Detection of Graphviz document formats could be improved by adding
> - either *.dot as glob pattern (conflicts with the more frequent MSWord
> templates)
> - a magic pattern which catches the [.dot
> language|http://www.graphviz.org/content/dot-language] grammar, eg.
> {{^\s*(?:strict\s+)?(?:di)?graph\b}}
> Seen with Common Crawl data (see also discussions on
> [user@tika|https://lists.apache.org/thread.html/1e4f4b6c249618a446f2e92f56ef90e6bfa0dfe51ce10197461df3d9@%3Cuser.tika.apache.org%3E]
> and

> web server sends "text/vnd.graphviz" (often wrong) and Tika detects
> "application/msword" (sometimes wrong), see [WARC
> file|https://commoncrawl-dev.s3.amazonaws.com/tika-content-type-detection/test/tika_dot_graphviz_msword.warc.gz]).
