In planning a research project, it is important that you consider which file formats you will use to store your data. The file formats in which you record, store, and transmit your data is a primary factor in the ability to use the data in the future. Since technology continually changes, researchers should plan for both hardware and software obsolescence.
In many cases, the file format used will be dictated by the software you have access to or the conventions of your discipline. However, for long-term preservation and ease of sharing, best practices dictate that the files be converted to a different format after your project has ended.
Whenever possible use uncompressed, unencrypted, non-proprietary (open) formats like the following:
Before you begin your research, adopt a naming convention for your files and use it throughout your project. Document the naming convention you choose, most likely in your ReadMe.txt file, and make sure that you and your collaborators follow it.
Data versioning refers to saving new copies of your files when you make changes so that you can go back and retrieve specific versions of your files later. Saving multiple versions makes it possible to decide at a later time that you prefer an earlier version. You can then immediately revert back to that version instead of having to retrace your steps to recreate it.
The following naming structure for data versioning is as follows:
