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 European and worldwide levels are we

21、ll 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 any other standard implies its lates

22、t edition, unless otherwise stated. BS EN 9300-012:2013EN 9300-012:2013 (E) 5 1 Scope This European Standard provides a detailed description for the recommended process of transferring data to the archive as overviewed in EN 9300-010. This transfer includes the conversion of the Content Information

23、into the archiving format STEP and the generation of the Archive Information Package. Furthermore, the main focus for the process description is on the validation and verification of the converted Content Information. 2 Normative references The following documents, in whole or in part, are normative

28、evious 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.org).

29、Figure 1 Overview of Ingest process During the Ingest process, the data producer submits the Submission Information Package (SIP) from the working environment into the archiving environment. The archive receives the data packages and checks if the SIP contains data of the recommended format and gene

30、rates the Archiving Information Package (AIP) afterwards. After submitting the SIP to the archive, the source data receives the status read only. Input data: SIP. Output data: AIP; Content Information (CI); SIP. 6 Detailed process steps description 6.1 General Input and output data described in this

31、 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, Section 5.3.2.1 “Definition of the core model”). BS EN 9300-012:2013EN 9300-012:2013 (E) 7 6

32、2 Submit for Ingest The producer initiates the submission of the SIP from his personal working environment to the archive. With the initiation of the submission the producer applies the approval for that SIP. A further change of the content data should not be possible otherwise the changed data sha

33、ll be archived by a new approval and data preparation process. Input data: SIP. Output data: SIP. 6.3 Receive data The archive receives the SIP for archiving from the producing system through data transfer. The SIP shall be kept within the archives working environment for further processing during t

34、he ingest process. Input data: SIP. Output data: SIP. 6.4 Check quality assurance A function within the Archive environment checks the quality of the ingested data. This includes the successful transfer of the SIP to the staging area. For digital submissions, these mechanisms may include Cyclic Redu

35、ndancy Checks (CRCs), or checksums associated with each data file, or the use of system log files to record and identify any file transfer, or checking for media read/write errors. In addition to OAIS recommendations, the function checks the types of data formats used and the existence of PDI within

36、 the received SIP. The exchanged data and its representations shall be stipulated in the ingest agreement between the archive and the producer. Stipulations may cover aspects such as CAD data formats and Model files or PDM data formats such as STEP. The agreement shall include, at a minimum, the spe

37、cification of: the key characteristics of the product information to preserve; the Descriptive Information of the SIP; the acceptance criteria used for the verification; the validation properties of the source information to archive; the related KPIs. Each agreement will be archived itself, as part

38、of the context information of the new category of product information to archive. Input data: SIP; Data formatting and document standards. BS EN 9300-012:2013EN 9300-012:2013 (E) 8 Output data: If the quality assurance check is successful: SIP; Confirmation Information. Otherwise: Error report. 6.5

39、Send confirmation The archive creates a report of the successful receiving of the SIP into the archives working environment. Input data: Confirmation Information. Output data: Confirmation report. 6.6 Generate AIP The archive performs the generation of an Archival Information Package (AIP) automatic

40、ally. This includes the conversion of the Content Information (with validation) from the submitted native format into the archiving format, the validation of the converted data, and the generation of any additional Preservation Descriptive information (PDI) and Descriptive Information (the meta data

41、 for the Content Information). “Generate AIP” shall ensure that the design intent of the source file of the producer is preserved conforming to the domain specific parts. It is based on the verification and on the validation of the key characteristics of the product data. Input data: SIP. Output dat

42、a: If generation is successful: AIP. If generation fails: Error report. The failure of the generation of the AIP is related to the conversion of the representation of the Content Information to its final format and its validation. 6.7 Approval Content Information This process step is recommended, bu

43、t not mandatory, and is applicable only to new data. This step synchronises with the producers engineering approval process (not shown), such that the final engineering approval is only given if the information passes the archiving criteria, and conversely, the archive only proceeds if the engineeri

44、ng approval is given. NOTE In effect, this step means that, if the data is not fit to archive, it is not fit to be approved for use. Since many of the archive checks should be performed automatically, putting archivability as a quality gate before engineering approval means that the cost of an addit

45、ional (expensive) engineering approval is avoided if the data needs rework in order to be archived. BS EN 9300-012:2013EN 9300-012:2013 (E) 9 Input data: AIP. Output data: AIP; CI. 6.8 Error handling for denied SIP The producer should perform an error check in the case that the data is rejected by t

46、he archive. Furthermore, the Producer should restart the Data Preparation, which includes the changing of the data, in order to make it fit to archive. Input data: Error report. Output data: SIP (identifying the data). 6.9 Receive Confirmation The producer receives the archives confirmation report.

47、Input data: Confirmation report. 6.10 Error handling for generate AIP Within this process the Producer and/or the Administrator has to perform an error handling procedure. This includes the decision whether data is still usable or has to be generated again. The administrator will be informed. Input

48、data: Error report. 7 Support Process Steps: Preservation Planning The process provides services and functions for monitoring the environment of the archive and recommendations to ensure that the information stored in the archive remains accessible to the consumer over the long term, even if the ori

49、ginal computing environment becomes obsolete. Preservation Planning functions include developing recommendations for archive standards and policies and monitoring changes in the technology environment, archiving format and the addressed consumer. Output data: Data formatting and document standards. 8 Data descriptions 8.1 General The descriptions here are informative; the definitions are found in EN 9300-007.
