Prefered file format

As a generalist repository, ScienceDB publishes data across all disciplines. As such, we do not impose restrictions on the format or subject area of a data submission. However, we have a preferred list of file formats which we think are conducive to data reusability and permanent accessibility. In the table below, we have listed both preferred and non-preferred formats as per each file type.

If the file format you use is not in our list, we suggest you evaluate it by the three criteria:

(1) whether the format is common in your discipline;

(2) whether the format has open standards;

(3) whether the format is independent of a peculiar software application, developer or supplier.

If the format you use is not in our list, your submission should meet all or most of the criteria above.
