35、.1 Introduction 4.1.1 General Different user communities have different definitions for long term archiving and retention. This clause explains the major differences of both terms and their relation to the scope of EN 9300. Companies within the aerospace industry need to keep data to fulfil business
36、, certification and legal requirements. For modern definitions this data is usually digital. These requirements lead to four main areas of consideration regarding the retention of digital data. Invariance: how important is it to ensure that digital data is not altered Objectives: why keeping of digi
37、tal data is required Length of time: the required length of time for retaining digital data Stored Form: the stored format of the digital data The following subchapters consider these questions for long term archiving and retention and are the basis for the scope definition of EN 9300. The scope of
38、EN 9300 is a combination of aspects from long term archiving and retention. 4.1.2 Invariance Invariance covers the need to ensure that the information has not changed and so provide evidential weight that the design intent has not changed, see Figure 13. Three categories can be distinguished: Audita
39、ble where validation methods and test suites ensure that information cannot be changed without the change being detected. Implicit where the system is designed to prevent changes. The system must supervise activities which would result in changes of the digital data. The supervision, for example, co
40、uld be realized within a separate write-protected vault. The proof of “no change“ is shown by an absence of change having been recorded AND that by showing that the system itself is reliable. Not required where changes to data are not explicitly controlled. Of the three, auditable invariance is the
41、strongest, and is likely to be the most suitable where the information is used in legal proceedings. 4.1.3 Objectives for keeping digital data For digital data, the challenge is that the data are often stored in a proprietary, native format and will most likely become not interpretable after a time.
42、 The use of a neutral archiving data format safeguards the interpretability of the stored data for a much longer time, perhaps for the entire retention period. EN 9300 recommends the use of standard formats for long term archiving rather than native formats, accompanied by regular and frequent migra
43、tions of storage media and, if necessary, of data format. Because a data migration may lead to data loss, usually time stamps and digital signatures (which are used ensuring the integrity and immutability of archived data/ data packages) have to be renewed. The use of auditable archiving and retriev
44、al processes ensures the data readability and integrity within current and future systems. BS EN 9300-003:2012EN 9300-003:2012 (E) 7 The objectives for keeping the data are distinguished into two major subcategories: Legal requirements/certification requirements, such as for proof of technical docum
45、entation for actions in law. Business requirements, such as keeping knowledge. Within the two subcategories EN 9300-003 offers four characteristics which describe the objectives in more detail: To preserve the original data (generated by a source system) so that it can be used as evidence of what da
46、ta was at a particular date. This characteristic fits with the subcategory legal requirement To keep data available to new users over the period for which it is kept. This characteristic fits with the subcategories legal requirement and business requirement. To be able to preserve the source of the
47、kept data. This characteristic fits with the subcategory business requirement. To be able to reuse the data, for example, by modifying design data to meet new requirements. This characteristic fits with the subcategory business requirement. 4.1.4 Length of time of keeping data The life cycle of soft
48、ware and hardware is relatively short compared to the life cycle of aircraft. The life cycle of digital data can be described in terms of software versions and generations. The release of a new software version within a generation general alters only a small part of the functionalities of the softwa
49、re without affecting the data format. A generation change occurs when the software used changes substantially, for example, to a new architecture. The change of a generation may result in new data formats. Currently, for CAD software, the period between versions is of the order of 6 months to 12 months, while between generations is of the order of 3 years to10 years. This should be compared
