[open-bibliography] Czech translation of Principles on Open Bibliographic Data

[Adrian Pohl]

Hello,

Jindrich Mynarz provided a Czech translation of the Principles on Open
Bibliographic Data: http://openbiblio.net/principles/cz/

Thank you, Jindrich!

It would be nice to add more translations of the principles to the
website. So, if you are native speaker in a language not yet covered:
think about it.

All the best
Adrian
