ESPD Validation Architecture

The validation of a ESPD XML has the following life-cycle:

ESPD Schematorn lyfe-cycle

The validation of the XML starts by ensuring that the input XML follows the structure defined by the XSD: QualificationApplicationRequest.xsd XSD Schema or QualificationApplicationResponse.xsd XSD Schema. These schemas can be found under the folder ubl-2.3/xsdrt/maindoc (or the equivalent documented xsd folder).
1. If the validation of the structure is not successful, the process stops and sends the report with the list of errors.
2. If the validation of the structure is successful, the process continues with the code list validations and business rules. All errors found (if any) are listed in the report.
Depending on the type of application (ESPD Request or ESPD Response), different types of validations are executed:

Validation Process

ESPD Request

XSD Validation against QualificationApplicationRequest-2.3.xsd
Code list validations. These are common for both, Request and Response:
1. Validation of the code list values: 01 ESPD-codelist-values.cva
2. Validation of the identification of the code list: 01 ESPD Common CL Attributes.sch
Business rules related to the cardinality of the schema, that cannot be controlled using the XSD: 02 ESPD Req Cardinality BR.sch
Business rules used to validate the criteria data structure:
1. Validations common for Request and Response: 03 ESPD Common Criterion BR.sch
2. Validations specific for Request applications: 03 ESPD Req Criterion BR.sch
Other business rules:
1. Other validations which are common to Request and Response applications, such as the mandatory use of the attribute schemeAgencyID for identifiers: 04 ESPD Common Other BR.sch
2. Specific business rules for Request applications, in this case, the validation of the correct value for cbc:CutomisationID element: 04 ESPD Req Other BR.sch
3. Business rules related to the procurer: 05 ESPD Req Procurer BR.sch
4. Specific business rules: 05 ESPD Req Specific BR.sch

XSD Validation against UBL-QualificationApplicationResponse-2.3.xsd
Code list validations. These are common for both, Request and Response:
1. Validation of the code list values: 01 ESPD-codelist-values.cva
2. Validation of the identification of the code list: 01 ESPD Common CL Attributes.sch
Business rules related to the cardinality of the schema, that cannot be controlled using the XSD: 02 ESPD Resp Cardinality BR.sch.sch
Business rules used to validate the criteria data structure:
1. Validations common for Request and Response: 03 ESPD Common Criterion BR.sch
2. Validations specific for Response applications: 03 ESPD Resp Criterion BR.sch
Other business rules:
1. Other validations which are common to Request and Response applications, such as the mandatory use of the attribute schemeAgencyID for identifiers: 04 ESPD Common Other BR.sch
2. Specific business rules for Response applications, in this case, the validation of the correct value for cbc:CutomisationID element: 04 ESPD Resp Other BR.sch
3. Business rules related to the economic operator: 05 ESPD Resp EO BR.sch
4. Response Specific business rules: 05 ESPD Resp Specific BR.sch
5. Specific business rules for economic operators registered in a pre-qualification system: 05 ESPD Resp Qualification BR.sch
6. Specific business rules depending on the role: 05 ESPD Resp Role BR.sch
