The PROSTEP iViP Association is an international non-profit asso
12、ciation 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 European and worldwide levels are well known a
13、nd accepted. The PROSTEP iViP Association sees this standard and the related parts as a milestone of product data technology. Users should note that all standards undergo revision from time to time and that any reference made herein to any other standard implies its latest edition, unless otherwise

15、ocess of transferring data to the archive as overviewed in EN 9300-010. This transfer includes the conversion of the Content Information into the archiving format STEP and the generation of the Archive Information Package. Further the main focus for the process description is on the validation and v
16、erification of the converted Content Information. 2 Normative references The following referenced documents are indispensable for the application of this document.

22、e 1. Figure 1 Overview of Ingest process During the Ingest process the data producer submits the Submission Information Package (SIP) from the working into the archiving environment. The archive receives the data packages and checks if the SIP contains data of the recommended format and generates th
23、e Archiving Information Package (AIP) afterwards. After submitting the SIP to the archive the source data gets 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 standard represe

25、l Aerospatial Provided by IHS under license with AECMA Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-prEN 9300-012:20066 6.2 Submit for Ingest The producer initiates the submission of the SIP from his personal working environment to the archive. With the initiati
26、on 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 must 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
27、for archiving from the producing system through data transfer. The SIP shall be kept within the archives working environment for further processing during the ingest process. Input data: SIP Output data: SIP 6.4 Check quality assurance A function within the Archive environment checks the quality of
28、the ingested data. This includes the successful transfer of the SIP to the staging area. For digital submissions, these mechanisms may include Cyclic Redundancy Checks (CRCs), or checksums associated with each data file, or the use of system log files to record and identify any file transfer, or che
29、cking 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 the received SIP. The exchanged data and its representations must be stipulated in the ingest agreement between the archive and the producer. Sti
30、pulations 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 specification of: the key characteristics of the product information to preserve, the Descriptive Information of the SIP, the acceptance criteria used
31、 for the verification, the validation properties of the source information to archive, the related KPIs. Each agreement will be archived itself, as part of the context information of the new category of product information to archive. Input data: SIP Data formatting and document standards Copyright

33、rwise: Error report 6.5 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 P
34、ackage (AIP) automatically. 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 Info
35、rmation (the meta data 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
36、 data: SIP Output data: 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
37、 is recommended, but not mandatory, and is applicable only to new data. This step synchronizes 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 procee
38、ds if the engineering 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 th
39、e cost of an additional (expensive) engineering approval is avoided if the data needs rework in order to be archived.

Further, the Producer should restart the Data Preparation, which includes the changing of the dat
41、a, 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. Input data: Confirmation report 6.10 Error handling for generate AIP Within this process the Producer and/or the Ad
42、ministrator 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 data: Error report 7 Support Process Steps: Preservation Planning The process provides services and functions for mo
43、nitoring 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 original computing environment becomes obsolete. Preservation Planning functions include developing recommendations for
44、archive standards and policies and monitoring changes in the technology environment, archiving format and the addressed consumer.

46、ch usual supports at least the key functions of an archiving architecture according to ISO 14721:2003 (OAIS). Key functions are administration, data management, archival storage, access control, preservation planning. 8.2.2 Producer The producer is an organization, person, or client system, which pr
47、ovides the information to be preserved. This can include other archives or internal archive personnel or system components. Typical roles of type “producer“ may be. System Designers, Design Engineers, Subcontractors, Manufactures or Test Engineers. 8.2.3 Approving team Represents the approving organ
48、izations of a company. The approving team approves the AIP before the AIP is stored within the Archive. 8.3 Involved data 8.3.1 Archival Information Package (AIP) The AIP consists of the following elements: Content Information (CI) (archiving formatted and optionally native formatted) Packaging Information (PI) Preservation Description Information (PDI) (Validation Properties, context information for the Content Information) Digital Signature Information The Content Information is the set of information that the producer require
