Licenses model

The iSHARE Framework contains the concept of Licenses, which allow an Entitled Party to explicitly specify what a Service Consumer is allowed to do with the consumption of a service or with received data. "Licenses" is an attribute which is included in the specifications for the /delegation endpoint (providing delegation evidence) and the /delegationPolicy endpoint (to request the creation of delegation policies). The licenses attribute can be utilised to define one or more licenses that apply to the outcome of a service (data) consumption. The following scenarios are recognised.

Single license

Only one license applies. This can be achieved by including one license identifier in the licenses attribute. The following example explains how.

Example: the received service (data) output may be used for internal use only

{
    "licenses": [
        "https://licenses.ishare.eu/general-internal-use/1.0"
    ]
}

Multiple licenses

Multiple licenses apply. To determine how the licenses relate to each other, it is possible to use the logical operators allOf and anyOf.

• This model allows for infinite nesting

• Best practice is to group licenses from the same category together

The following examples explain how this can be applied.

Example: the received service (data) output may be used internally or to service an Entitled Party

{
  "licenses": [
    {
      "anyOf": [
        "https://licenses.ishare.eu/general-internal-use/1.0",
        "https://licenses.ishare.eu/general-use-to-service-entitled-party/1.0"
      ]
    }
  ]
}

Example: the received service (data) output may be used internally in the Netherlands or Belgium

{
  "licenses": [
    {
      "allOf": [
        "https://licenses.ishare.eu/general-non-commercial-use/1.0",
        {
          "anyOf": [
            "https://licenses.ishare.eu/country/nl/1.0",
            "https://licenses.ishare.eu/country/be/1.0"
          ]
        }
      ]
    }
  ]
}

Example: the received service (data) output may be reshared with iSHARE adhering parties in the Netherlands or Belgium that are ISO27001 certified

{
  "licenses": [
    {
      "allOf": [
        "https://licenses.ishare.eu/general/resharing-with-adhering-parties/1.0",
        {
          "allOf": [
            {
              "anyOf": [
                "https://licenses.ishare.eu/country/nl",
                "https://licenses.ishare.eu/country/be"
              ]
            },
            "https://licenses.ishare.eu/certification-iso-27001/1.0"
          ]
        }
      ]
    }
  ]
}
