Evidences

See formal requirements related to evidences in the e-Sens site: (tbr092-017).

XSD Schema

Remember that evidences are indirectly linked to responses based on the identifier of the evidence: in the response, the element cac:EvidenceSupplied/cbc:ID contains the identifier set in /QualificationApplicationResponse/cac:Evidence/cbc:ID. See XML example below; see also the example XML file ESPD-Response.xml for an example.

The figure below shows the XSD Diagram for the UBL-2.3 component cac:Evidence (elements in blue are the expected ones in ESPD-EDM):

cac:Evidence XSD diagram

Figure 241. cac:Evidence XSD diagram

The UBL-2.3 element cac:Evidence is a specialisation of cac:DocumentReference. This other XSD diagram shows this association and, in blue, highlights the elements expected in the ESPD-EDM:

Mock-ups and data structures

In principle only a few elements are kept in the ESPD Response document about an evidence: its Identifier, a URL from where to access its content, a Reference/Code, a Confidentiality indicator, and the Issuer.

This group of data repeats frequently in the many different mock-ups presented in this document. The one below is just one example and will be used to illustrate where the three element go in the XML instance of an evidence.

Duplicity of the Issuer

Beware that the current model of UBL-2.3 provides two elements for the Issuer, one for the issuer of the evidence and another for the issuer of the document reference.

The ESPD-EDM uses always the one inside the document reference to refer to the issuer of the evidence (and of the document that 'is' the evidence). Thus the element used in the ESPD is cac:Evidence/cac:DocumentReference/cac:IssuerParty/cac:PartyIdentification/cbc:ID.

Expected (and other) Elements

This list below enumerates the elements of cac:Evidence that could be used in (that make sense for) an ESPD Response. Notice though that the current versions of the ESPD-EDM only use the few elements mentioned above: ID, URL, Reference/Code, Confidentiality level and Issuer.

Table 44. Elements expected in an Evidence

Class name:

cac:Evidence

Class name:

cac:DocumentReference

Definition:

A reference to the evidentiary document.

Business rule(s):

None

File:

ubl-2.3/xsdrt/common/UBL-CommonAggregateComponents-2.3.xsd

Rule: If the reference or verification code is provided for the evidence use this element to place it. This 'code' is used in some countries (e.g. Spain) to check that the document is authentic. If a verification code is supplied you can use an official 'end-point' to retrieve an image (or a PDF) of the document and check that the evidence is authentic.

XML Examples

Example 1: Two different evidences for two criteria

The following snippet uses the same two criteria shown in the XML example snippet 1.a): hence the values of the cac:ValidatedCriterionPropertyID are 'd8d5478e-cc65-48c9-a189-19bbe87a9bfd' (criterion property 'participation in a criminal organisation') and '7c7fb445-c5f9-4f92-8b58-7f06a541951f' (criterion property 'contributions certificates').

  1. ID value of the first criterion property (QUESTION) for which this response value is the answer.

  2. The criteron is to be treated as 'PUBLIC': it could be published.

  3. Identifier of the first evidence object that is used for this criterion: it must match the value provided for the cac:Evidence/cbc:ID element of the evidence.

  4. ID value of the second criterion property (QUESTION) for which this response value is the answer.

  5. Confidentiality level is set to 'CONFIDENTIAL'. Therefore the evidence linked to this response will also be treated as 'CONFIDENTIAL'.

  6. Identifier of the second evidence object that is used for this second criterion: it must match the value provided for the cac:Evidence/cbc:ID element of the evidence.

  7. The identifier of the first evidence. It matches the cac:EvidenceSupplied/cbc:ID element value of the first response.

  8. Confidentiality code for the first evidence: 'PUBLIC', notice that it is consistent with the fact that the response is also set as 'PUBLIC'.

  9. Verification code ID for the first evidence (a 13 digit EAN-13 barcode number in this case).

  10. URL from where to get the document. The fact that the evidence MUST BE treated as CONFIDENTIAL is not inconsistent with the fact that the evidence is available online from a free-of-charge national data base.

  11. The name of the issuer of the first evidenciary document.

  12. ID of the second criterion property (QUESTION) for which this response value is the answer.

  13. The criteron is to be treated as 'CONFIDENTIAL': addressed only to the evaluators.

  14. Verification code ID of the second evidence.

  15. URL from where to get the document.

  16. The name of the issuer of the second evidenciary document.
