The IDS captures as much available information from the RAW files as possible, such as:

• time - Time that the data set is related to
• system(s) - Equipment used to produce the result, software, and firmware
• user(s) - Person who performed the experiment
• sample(s) - Sample used in the experiment
• method(s) - Experimental recipe and input parameters
• run(s) - A particular execution of the experiment
• experiment(s) - Information about the experiment, id, name, and so on
• result(s) - Measurement results
• related_file(s) - Pointer(s) to related files (for example, raw experimental data sets in the vendor specific, and often proprietary, format)
• datacubes - Multi-dimensional data such as chromatogram, images, plate readings, and so on

IDS JSON Example

An example of an IDS JSON is below:

• Three pieces of information are used to uniquely identify the IDS:
  "@idsType": "cell-counter",
  "@idsVersion": "v1.0.0",
  "@idsNamespace": "common,

• Items such as the run, time, sample, method, user, and results are also included.
