13、se cases .19 Bibliography 26 BS ISO 24517-1:2008vForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each

14、member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International

15、 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards

16、adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of

17、patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 24517-1 was prepared by Technical Committee ISO/TC 171, Document management applications, Subcommittee SC 2, Application issues. ISO 24517 consists of the following parts, under the general title Docu

18、ment management Engineering document format using PDF: Part 1: Use of PDF 1.6 (PDF/E-1) BS ISO 24517-1:2008vi Introduction The ISO 24517 series defines a file format for the exchange of engineering documents based on the PDF format for various communities working with engineering documentation. It i

19、s a multi-part standard with subsequent parts expected to address future workflow and data requirements. The ISO 24517 series improves document exchange, collaboration, and print accuracy within engineering workflows, both inside companies and with extended enterprises of partners, suppliers, custom

20、ers, government organizations and citizens. It will enable organizations to streamline engineering workflows that incorporate diverse sets of complex documents, resulting in improved productivity and the ability to more quickly deliver better products to market. It defines the features of PDF that a

21、re required, recommended, restricted, or prohibited when creating, viewing, marking up, printing, analysing, and distributing engineering documents. It takes into consideration the differing needs of both interactive and non-interactive readers. The ISO 24517 series specifies the proper use of PDF f

22、or on-screen display and printing of engineering documents. Printed engineering documents are assemblies of a page (or pages) created by different organizations which can be inter-departmental or inter-company. It also defines a framework for representing the logical structure and other semantic inf

23、ormation of engineering documents within conforming files. The ISO 24517 series is intended to provide a format for the development of various applications, such as products that read, render, write, print, and validate PDF conforming documents. Different products will incorporate various capabiliti

24、es to prepare, interpret, and process conforming objects. Adobe Systems Incorporated makes the PDF specification publicly available. However, the inclusive, feature-rich nature of the format requires that additional constraints be placed on its use to make it suitable for engineering workflow docume

25、nts. PDF/E allows engineering professionals to reliably create, exchange, and review engineering documentation, including large format documents. PDF/E enables organizations to work more effectively when creating or exchanging engineering documentation. AIIM, an accredited standards developing organ

26、ization, maintains an ongoing series of application notes for guiding developers and users of this part of ISO 24517. These application notes are available at http:/www.aiim.org/. AIIM will also retain copies of the specific non-ISO normative references of this part of ISO 24517 which are publicly a

27、vailable electronic documents.

41、 ISO/IEC 10646 character name written in uppercase in bold sans serif font followed by a parenthetic four-digit hexadecimal character code value with the prefix “U+”. EXAMPLE 3 EN SPACE (U+2002). 5 PDF/E-1 conforming files and readers This part of ISO 24517 specifies the use of the PDF file format f

42、or the exchange of digital data representing a compound entity. A PDF/E-1 conforming file is a PDF file in which those features necessary for the exchange of a compound entity are in accordance with this part of ISO 24517. A PDF/E-1 conforming file may also include other valid PDF features that do n

43、ot affect display or function of the compound entity. PDF/E-1 conformance is identified by use of the pdfe:ISO_PDFEVersion property as defined in 13.3. The value of the ISO_PDFEVersion key in the document information dictionary shall be PDF/E-1 for a PDF/E-1 conforming file. Neither the version numb

44、er in the header of a PDF file, nor the value of the Version key in the Catalog of a PDF file indicates that a file is in accordance with this part of ISO 24517. NOTE 1 These values are specified in Table 1 of 13.3. Although PDF Reference permits compliance with earlier versions of PDF, features des

45、cribed in versions of the PDF specification earlier than 1.6, but not described in PDF Reference, shall not be used in a PDF/E-1 conforming file. A PDF/E-1 conforming writer is a software application that is able to write files in accordance with the requirements of this part of ISO 24517. A PDF/E-1

46、 conforming reader is a software application that shall be able to read and appropriately process all PDF/E-1 files in a manner conforming to the requirements for PDF/E-1 files as defined in this part of ISO 24517. A PDF/E-1 conforming reader may parse PDF files that are not PDF/E-1 conforming files

47、. The behaviour of a PDF/E-1 conforming reader on non-conforming files is beyond the scope of this part of ISO 24517. Rendering of PDF/E-1 conforming files shall be performed as defined in the PDF Reference and as restricted by this part of ISO 24517. To the extent that the PDF Reference and this pa

48、rt of ISO 24517 permit more than one rendering of a PDF/E-1 conforming file, a PDF/E-1 conforming reader may use embedded job ticket or metadata information to control the rendering of the file more precisely. Furthermore, interactive PDF/E-1 BS ISO 24517-1:20084 conforming readers may provide user

49、interface elements to control dynamic features of PDF/E-1 such as optional content, three dimensional (3D) and multimedia. NOTE 2 A PDF/E-1 conforming file is not obligated to use any PDF feature other than those explicitly required by the PDF Reference or this part of ISO 24517. 6 Syntax 6.1 File header The % character of the file header shall occur at byte offset 0 of the file. 6.2 File trailer The file trailer dictionary shall contain the ID keyword.
