| 1 | Each column contains a unique attribute name (between upper and lower case not differentiated z. B. “beetles” and “Beetles” |
| 2 | **Column delimiter** is consistent and clearly identifies throughout the table (e. g. ”;” or “,”) |
| 3 | Column names contain **no spaces** (an underscore „_“ is allowed to use), special characters, umlauts, “ß” or units |
| 4 | Column names are a maximum of 30 characters long |
| 5 | Column names **do not** start with a number |
| 6 | Column names are only assigned **once**
| 7 | Values within a column are constant (**no change of reference variable or unit**) |

| 3 | Only one value specified per cell |
| 4 | Cells **are not** connected |
| 5 | Cells do not contain separators such as “;” (decimal numbers are uniformly written with “.” or “,” and differ from column delimiter) |
| 6 | Cells contain no spaces |
