Da am 2018-06-04 bekannt wurde, dass Microsoft kauft, und ich Github daher nicht mehr als neutrale Plattform ansehen kann ziehe ich die ehemals dort aufgeführten Repositorien um. Zur Zeit bin ich noch am Umziehen auf einen eigenen Gitea-Server unter Der Quellcode ist in der Zwischenzeit per Mail unter git At anfragbar, bzw. nachstehend verlinkt.

libcbag - a free and opensource C++ Library to handle BagIt structures

BagIt is a standard format to create transfer packages for digital preservation purposes.

A CLI based conformance checker to validate (baseline) TIFF files against self defined rules. It works in different way than other tools. Instead to use a hardcoded rule set with predefined values, you are able to define tags and corresponding values more fine granulary. The rulesets are human readable and could be adapted to own needs. The "checkit_tiff" works on commandline and therefore it is embeddable in scripts.

FFV1/Matroska Factsheet for Managment/Decision-makers

This repository helds a fact sheet about Matroska/FFV1. It uses the leaflet LaTeX template and could compiled with XeLaTeX:

Script to use Matroska Menus (matroska chapter link) to link MKV files together. This allows to use one file only referencing other matroska-files. It uses the chapter method of matroska to link files together. This means the resulting Matroska file is very small and only links to all given Matroska files. See for detailed explanation. The movieplayer "mpv" should be able to play such files. Also the upcoming VLC will support this (around year 2018).
