 |Unknowns|`True`/`False`|Does the dataset contain known/unknown data? Binding data from chemogenomics datasets, for example, are positive-unlabeled, so they do contain unknowns. Conversely, chemical fingreprints or gene expression data do not contain unknowns.|
-|Permanent|`True`/`False`|Are measurements for each entry permanent? 2D fingerprints, for example, are permanent. However, most of biological data may change/evolve with the different versions of the CC. This field, in essence, dictates whether the dataset should be completely updated in every update of the CC, or whether new entries can be simply appended.|

 |Data type|`Discrete`/`Continuous`|The type of data that ultimately expresses de dataset, after the pre-processing. Categorical variables are not allowed; they must be converted to one-hot encoding or binarized. Mixed variables are not allowed, either.|

 |Features|e.g. `GEN` (we use `Bioteque` nomenclature). May be `NULL`.|When features correspond to explicit knowledge, such as proteins, gene ontology processes, or indications, we express with this field the type of biological entities. It is not allowed to mix different feature types. Features can, however, have no type, typically when they come from a heavily-processed dataset, such as gene-expression data. Even if we use `Bioteque` nomenclature to the define the type of biological data, it is not mandatory that the vocabularies are the ones used by the `Bioteque`; for example, I can use non-human Uniprot ACs, if I deem it necessary.|
