19、Association is an international non-profit association in Europe. For establishing leadership in IT-based engineering it offers a moderated platform to its nearly 200 members from leading industries, system vendors and research institutions. Its product and process data standardization activities at
20、 European and worldwide levels are well known and accepted. The PROSTEP iViP Association sees this European Standard and the related parts as a milestone of product data technology. Users should note that all European Standards undergo revision from time to time and that any reference made herein to
21、 any other standard implies its latest edition, unless otherwise stated.

26、duct data records, on current and earlier products, produced using previous regulations, standards and procedures. The current version is focused on product data as defined in the domain specific parts. 1) Published as ASD-STAN Prestandard at the date of publication of this standard (www.asd-stan.or

This includes a defined data verification, performed by a Quality Agent tool. The data verification will test the data against de
28、fined data quality requirements, and will provide a result report. Data preparation also includes the creation of Validation properties. The sub process shall be certified. Output data: Submission Information Package (SIP), reset archiving trigger information, process control data, error fixing repo
29、rt. 6 Detailed process steps description 6.1 General Input and output data described in this standard represent the minimal requirements for the fulfilment of the process steps. Additional data may be added, but shall match at a minimum the requirements for the information package (see EN 9300-003,
30、Section 5.3.2.1 “Definition of the core model”). 6.2 Select data for archiving The producer selects data for archiving during, for example, a domain depended release process (this is outside the scope of EN 9300). As an example, the selection can be performed at a product structure viewer of a CAD/P
31、DM system. The process step represents the initial trigger for the archiving process. The selected e.g. CAD or PDM information defines the Content Information (CI) of the future SIP. BS EN 9300-011:2013EN 9300-011:2013 (E) 7 Input data: CI; error report for producer of process step number 10: error
32、handling for data preparation; process control data. Output data: CI. 6.3 Initiate quality agent The producer will trigger the process manually. The system tool “quality agent“ automatically creates Validation properties from the data and checks if the data meets with the recommended data quality cr
33、iteria. It is recommended that the process step is synchronised with the producers own release process. Input data: CI. Output data: CI. 6.4 Data verification Whereas the purpose of validation is to ensure that the right information has been captured, the intention of verification is to ensure that
34、the data is correctly represented. Verification rules shall ensure that a data representation meet the quality requirements within defined tolerances. Verification is successful if no verification rule is violated. The verification rules are domain specific and are defined within EN 9300 (for exampl
35、e, verification rules for CAD are described in the 100 series parts of EN 9300). Only verification rules belonging to the core models are part of EN 9300. The down stream processes and the data outputs are determined by the result of the “data verification”. Input data: CI; data quality rules. Outpu
36、t data: If data verification is successful: CI; reference to Results report (the integration of this information into the Descriptive Information is optional); Results report. If data verification fails: data preparation error report. 6.5 Automatic creation of Validation properties? The producer has
37、 to decide if a manual or automatic creation of Validation properties is possible. Input data: CI. BS EN 9300-011:2013EN 9300-011:2013 (E) 8 Output data: CI. 6.6 Automatic creation of Validation properties The Producer initiates the source system to calculate Validation properties automatically. The
38、 Validation properties are used later for validation within the process step “INGEST Generate AIP“. Possible Validation properties are: Validation properties for 3D CAD Data, e.g. weight, centre of gravity, etc.; Validation properties for PDM product structure information; (future: Validation proper
39、ties for CAx and electric harness, etc.). It is recommended that Validation properties be extracted from the Content Information directly. Alternatively, Validation properties can be generated manually and saved within the Preservation Description Information (PDI). The sub processes detailing the s
40、pecific actions in case of failure or success of the creation of Validation properties are not represented. Where needed, they will be detailed in the recommended practices associated with part 11. Input data: CI; Validation property rules data. Output data: CI; Validation properties. 6.7 Create PDI
41、 The producer creates the Preservation Description Information (PDI). The PDI is the information which is necessary for adequate preservation of the Content Information and which can be categorised as Provenance, Reference, Fixity, and Context information. As an addition for EN 9300, the producer sh
42、all integrate Validation properties information into the PDI to ensure the existence of Validation Properties for later automatic validation processes. A further addition belongs to the Proprietary Rights: product data may be covered by proprietary rights that shall be protected. All information tha
43、t the Producer wishes to declare as proprietary shall be identified as proprietary. Information regarding proprietary rights shall be associated with the product data to assure the information is appropriately marked to provide the protection warranted such product data. PDI is categorised as: Prove
44、nance: the integrity of an information object is partly embodied in tracing where it came from. To preserve the integrity of an information object, digital archives shall preserve a record of its origin and chain of custody. Reference: provides one or more identifiers, or systems of identifiers, by
45、which the Content Information may be uniquely identified. Fixity: if an object is not fixed, and the content is subject to change or withdrawal without notice, then its integrity may be compromised. Fixity information prevents such change. BS EN 9300-011:2013EN 9300-011:2013 (E) 9 Context: Context d
46、escribes how the Content Information relates to other information outside the Information Package. For example, it would describe why the Content Information was produced, and it may include a description of how it relates to another Content Information object. Input data: Validation properties; Res
47、ults report. Output data: If creation of PDI is successful: PDI. If creation of PDI fails: Reset archiving trigger information. 6.8 Create Descriptive Information The producer creates a set of Descriptive Information (DI), which includes archive meta data meeting the archives requirements (according
48、 to ISO 14721:2003 OAIS). The descriptive information includes a reference to the data verification results report. Input data: Results report, as reference information. Output data: DI. 6.9 Create SIP The producer creates a SIP by combining the DI, PDI and CI into one package. The SIP contains also
49、 Packaging Information (PI). The PI is that information which, either actually or logically, binds, identifies and relates the CI and PDI. The SIP will be transferred to the archive. The formats of the packages are defined in a submission agreement between the producer and the archive. Input data: CI; PDI; DI; PI. Output data: SIP. 6.10 Manual creation Validation properties The producer shall be able to create a set of predefined Validation properties manua
