Standards and Formats

Basic principles

CLARIN adheres to the following principles:

• Open standards are preferred over proprietary standards
• Formats and protocols should be:
  • well-documented
  • verifiable
  • proven (being used in practice)
• Text-based formats are (where possible) preferred over binary formats
• In the case of digitisation of an analogue signal, using no or lossless compression is recommended
