For a Cozy Note, here is the list:

title: {string} - The Note’s title
version: {int} - The Note’s version

Document qualification¶

It is possible to add semantics to documents in order to qualify them.

A qualification model is available here that describes the qualification attributes for a set of documents. A qualification consists of a label bound to some fixed attributes, i.e.purpose, sourceCategory, sourceSubCategory and subjects, all explained in the next section. Note that for a given label, it is possible to customize the model attributes values, by following these rules:

If a value is defined for the attributes purpose, sourceCategory,sourceSubCategory, it is not possible to customize it.
If a value is not defined for one of these attributes, a custom value can be defined, if it exists in their respective known values list in the model, e.g. knownSourceCategory.
If some subjects values are set, they must be included in the given qualification.
Extra subjects values can be set, but they should exist in the subjectsKnownValues model list.

A document qualification is typically set by konnectors or by applications such as Cozy Drive through the cozy-scanner library.

Data structure¶

Example¶

Here is a qualification example:

{
  "qualification": {
    "label": "driver_license",
    "purpose": "attestation",
    "sourceCategory": "gov",
    "sourceSubCategory": "transport",
    "subjects": ["permit", "driving"] }
}

Qualification attributes¶

A qualification can be composed of the following attributes:

label: {string} the document label, which precisely specify what is the document. It is the only mandatory attribute in the qualification.
Examples: driver_license, car_insurance, bank_statement, etc.
purpose: {string} the goal of the document: for instance, an identity document has an attestation goal, to attest an identity. In the same manner, the purpose of a bill is to invoice something.
Examples: attestation, invoice, contract, report, etc.
sourceCategory: {string} the activity field of the source that produced the document.
Examples: gov, bank, health, transport, etc.
sourceSubCategory: {string} a precision of the activity field of the source that produced the document. In some cases, it is necessary when the primary field is too broad. Typically, for the driver_license label, gov is the sourceCategory and transport the sourceSubCategory.
Examples: transport, health, civil_registration, health, etc.
subjects: {array of strings} list what the document is about. For instance, a driver_license has two subjects: permit and driving, because this document is about the permit to drive a vehicle. Another example is the car_insurance: the subjects are insurance and car.
Examples: permit, insurance, house, car, etc.

For a complete list of the possible values for each attributes, see the qualification model.

If you need to add new values, please consider opening an issue or making a pull request to the cozy-client repository.
