> New Detector and Parser classes for Time Stamped Data Envelope file format
> --------------------------------------------------------------------------
>
> Key: TIKA-2309
> URL: https://issues.apache.org/jira/browse/TIKA-2309
> Project: Tika
> Issue Type: Improvement
> Components: detector, parser
> Affects Versions: 1.13, 1.14
> Reporter: Fabio
> Priority: Minor
> Attachments: MANIFEST.XML.TSD
>
>
> Hello,
> I'm Fabio Evangelista from Rome. I'm working for an italian Public
> Administration company and i'm using Apache Tika in my Java applications to
> detect and parse a broad kinds of file formats. During that activity, after
> following your good guide on Tika project page, I've made with success new
> type of Detector and Parser classes for a particular crypto timestamp type
> with these caracteristics:
> Format name: Time Stamped Data Envelope
> Mime Type: application/timestamped-data
> File extension: .tsd
> TSD file hax magic code at the start of the file: 30 80 06 0B 2A 86 48 86 F7
> I've integrated and tested successfully with my applications those new
> classes in Tika 1.13 tika-core.jar and tika-parsers.jar. What should I do to
> submit my new classes to you? Should I to push those in a particular git
> branch or, is there a particular process to follow to submit my classes?
> Thank you for you patience and best regards.
> Fabio.
