From investigating molecular vibrations to observing galaxies, terahertz
technology has found extensive applications in research and development over
the past three decades. Terahertz time-domain spectroscopy and imaging have
experienced significant growth and now dominate spectral observations ranging
from 0.1 to 10 THz. However, the lack of standardised protocols for data
processing, dissemination, and archiving poses challenges in collaborating and
sharing terahertz data between research groups. To tackle these challenges, we
present the dotTHz project, which introduces a standardised terahertz data
format and the associated open-source tools for processing and interpretation
of dotTHz files. The dotTHz project aims to facilitate seamless data processing
and analysis by providing a common framework. All software components are
released under the MIT licence through GitHub repositories to encourage
widespread adoption, modification, and collaboration. We invite the terahertz
community to actively contribute to the dotTHz project, fostering the
development of additional tools that encompass a greater breadth and depth of
functionality. By working together, we can establish a comprehensive suite of
resources that benefit the entire terahertz community
