Event Profile
Mature harvesting events are identified by the following characteristics:
KDE | Value |
type | TransformationEvent |
bizStep | commissioning |
disposition | active |
productClassification of mature.KDE Requirements
The following KDEs are required on the root of a mature harvesting event, in addition to the Core and Seafood requirements.
| KDE | Description | Example Value |
|---|---|---|
| bizLocation | Facility where the seafood was harvested; validated as a GLN with related master data | urn:epc:id:gln:1234567890123 |
| readPoint | A readPoint object with an id property equal to a geo formatted coordinate pair |
geo:37.860236,-123.144697 |
| informationProvider | A URN formatted PGLN or GDST party identifier | urn:epc:id:sgln:08600031303.0.0, urn:gdst:example.org:party:example_prefix.0 |
| productOwner | A URN formatted PGLN or GDST party identifier | urn:epc:id:sgln:08600031303.0.0, urn:gdst:example.org:party:example_prefix.0 |
| humanWelfarePolicy | Indicates whether a human welfare policy was in place during the event | internal policy, 3P audit, none |
Instance Lot Master Data (ILMD) Requirements
The following properties should be on the ilmd property of the mature harvesting event.
| KDE | Description | Example Value |
|---|---|---|
| productionMethodForFishAndSeafoodCode | Code specifying how the seafood was cultivated; must match a value from the GS1 code list ProductionMethodForFishAndSeafoodCode (version 15) | (valid list code) |
| aquacultureMethod | Farming method from FAO’s Aquaculture Methods and Practices (e.g. extensive, semi-intensive, intensive). Reference: FAO aquaculture methods | extensive, semi-intensive, intensive |
Certificate Requirements
| A mature harvest event must carry at least one complete certificate in its certificationList, either on the event or in the ilmd. GDST 2.0 does not name certification types in its normative event profiles; the controlled list of supported values is maintained in the Certification Types article.
Certificates are required to have the following properties
| Certificate Property | Description | Example Value |
|---|---|---|
| certificationType | A URN formatted string defining the type of certificate | urn:gdst:certType:harvestCert |
| certificationAgency | The name of the certificate program owner | WHO |
| certificationStandard | The name of the standard associated with the certificate | WHO Human Decency Policy |
| certificationValue | An additional descriptor of the certificate if there are different quality values for the certificate | Quality class 4 |
| certificationIdentification | The ID of the certificate | 0987654321 |
