— package verification rules: verifS’ the correctness and completeness of the meta-data included in the archival package.
8.4.2 Content verification
Content verification rules are defined to check the consistency and integrity of the configured baseline data while the data is archived. They are grouped according to the verification levels Into mandatory and optional rules.
Content verification rules shall be applied to the STEP file containing the product data that is targeted for archival, structured in accordance with an identified data specification and syntax.
This means that, in the archival process where native data are transformed into the standardized format, the verification rules are applied after the transformation process. Verification of content in native or proprietary system formats is out of scope. Verification of translation from native or proprietary formats to STEP format is out of scope for EN 9300-2xx.
8.4.2.1 Verification level I — Mandatory rules
The verification level 1 for EN 9300-2xx series includes the following rules:
— The syntax and specification requirement shall be verified for all levels.
— STEP native rules: STEP information models already include a wide set of default rules, defining constraints used to verify the content of STEP files that are compliant with the standard. Typical rules include uniqueness constraints, type verification, completion of attribute selection, usage of default values for attributes, etc. These rules are embedded in the Information model schemas and they are automatically inherited in this standard for any subset that is part of the scope. They are executed during the archival process to validate the content information and to assure a correct usage of the information model.
— Template mandatory rules: For information models defined in PLCS DEXes, each template defines specific rules on how to instantiate the entities covered by it. The verification rules that are mandatory shall be verified. For the standard templates, refer to DEXIib to see the definition of the rules. The rules for any new templates defined for EN 9300-2xx series DEXes are described in the specific EN 9300-2xx series sub-parts.
— Inclusion of mandatory essential information: inclusion of the mandatory essential information as described in 8.3 and in individual use cases shall be verified. Some of the requirements are covered by templates, in which case the rules are included in the previous group.
— Inclusion of conditional essential information: inclusion of conditional essential information as described in 8.3 and in individual use cases becomes mandatory when the associated condition is satisfied. For example, if archiving of certain information is conditional on the inclusion of a type of data object (e.g. Documents), then the inclusion of all the essential information associated with the type of data shall be verified.
8.4.2.2 Verification level 2 – Mandatory plus optional rules
The verification level 2 for EN 9300-2xx series includes the following rules:
— All checks required for verification level 1;
— Inclusion of optional Information: Information models may define optional information that may be attached to the configuration baseline. If included in the archive, the content of optional information shall be verified;
— Company specific rules: Each company may define their own specific verification rules to be
applied in the archival process.
8.4.3 Validation rules
Validation is applied to guarantee the integrity of the content during the archival process, which is done by calculation and comparison of validation properties.
The validation properties and associated thresholds shall be defined prior to the execution of the validation procedures. These shall be stored in a way that allows the automatic processing of the properties. For example, in a text file with a specific format defined for the purpose, or in a file with a standardised format such as STEP.
The validation procedures are then executed against the configured baseline data calculating results for each validation property, which Is then compared to the initial values specified in a validation property file.
The validation procedures shall be executed during the ingest process (EN 9300-012) and also in the retrieval process (EN 9300—0 14). A qualification report shall be produced during the ingest process, which in case of validation failure is sent to the producer in order for him to take the appropriate actions to correct the errors. In case the validation process yields the result “Passed’, the qualification report and the validation property file shall be included in the AlP and archived together with the configured baseline data.BS/EN 9300-200-2018 pdf download.
