The operational user of technical manuals and publications requires ease of ability to locate specific technical information contained in a given tech
16、nical manual. The user should be able to randomly access the following information elements, which must be indexed accordingly: - a given document (in a library sense) - the cover of the given technical manual - the list of effective pages - the record of changes - the promulgation letter - the tabl
17、e of contents - the list of illustrations .-a the list of tables - the document index (if the document contains one) - a given table - a given figure (or foldout) - agivenpage - a given paragraph or sub-paragraph - warnings and cautions At the current time, indexing for keywords and key phrases, out
18、side of that already contained in an existing hardcopy clocurnent iridex (if the document Lotitaii7s orre), IS riot rieeded for the scariried pages. Therefore, there is no current requirement for explicit content tagging. This Specification supports hypertext search and retrieval mechanisms (.e., no
19、n-linear text), as well as emerging auto- indexing and auto-tagging concepts. 3.2 SiJecification ConcePt. Figure 3-1 depicts the logical file structure for the interchange of technical manual scanned information. The file structure is consistent with magnetic tapes as defined in MIL-STD-l840A, but i
20、s extensible to random access magnetic and optical storage media. Far a given technical publication on any given technical inforrnation exchange medium, there shall be: - a Document Declaration File (per MIL-STD-1840A) with data entered into specific records. The Document Declaration File is require
21、d by MIL-STD-1840A. MIL-STD-1840A defines the block length for magnetic tape. In this Specification, several records in the Document Declaration File have been broadened in scope and further defined to contain document-level data elements. Additionally, this Specification extends the indexing of MIL
22、-STD-1840A to allow a particular record tag to be used more than once (.e., duplicated). There shall be one Document Declaration File for each technical publication contained on the exchange medium. Document-level indexing information contained within the Document Declaration File will be assimilate
23、d into the master library. -at least one Data File (and likely many data files) which contain the information content of the technical publication. Per MIL-STD-I840A, data files may contain: SCML-tagged (Standard Generalized Markup Language) text, a Document Type Definition (DTD) containing no telit
24、uai data, an output specification for a targeted composition or electronic display system, IGES data (Initial Graphics Exchange Specification), a raster image, CGM data (Computer Graphics Metafile), special word files, Page Description Language (PDL) data, and Grey-Scale (or halftone) data. Each dat
25、a file shall have identifying header records. This Specification defines the data file header records in greater detail than MIL-STD-140A. Specifically, the “notes” record in the data files has been broadened in scope and further defined to contain data elements for the technical information content
26、 conveyed in the data file. Also, this Specification extends MIL-STD-184A to allow duplication of header records. Duplicated header records will be added at the end of the core e 3- 1 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-O FILE STRUCTURE D

30、. This indexing information is intended to be assimilated into the master library. 3.3 ocument Declaration File. For magnetic tape, the Document Declaration File shall be the first file on the medium. For media which support random access, the Document Declaration File shall contain data elements wh
31、ich point to the data files which comprise the document. Each record within the Document Declaration File has a dedicated use, and each record is required. For magnetic tape, the Declaration File shall precede the data files of the document. Per MIL-STD-1 WOA, if more than one document is contained
32、on the magnetic tape, all of the declaration files shall be grouped at the beginning of the sequence of files in order to facilitate locating specific documents. For mag- netic tape, the group of text and illustration files (Le., the data files) which constitute a specific document may be in any ord
33、er, but the group shall be contiguous. Restrictions on physical file order of the Document Declaration File and associated data files do not apply to random access media. As currently defined in MIL-STD-1841)A. the Documsnt Declaration Filo contains some (but not all) record definitionswhich are nee
34、ded for indexing and retrieval at the master library level. Per MIL- STD-11540A, the Document Declaration File contains both a Declaration File Name and Declaration File Data. All of the data written in the Document Declaration File shall be in ASCII character format. The records shall be ANSI Type
35、D variable- length records with a maximum record length of 256 bytes (and block lengths of 2048 bytes for magnetic tape). MIL-STD-1840A currently intends that the detailed content ancl format of information appearing in the Document Dedaration File be specified by contract or other agreement prior t
36、o actual transmission of documents. Indexing information contained in the Document Declaration File described in MIL-STD-1840A currently includes: - Declaration File Name - Character string identifying the source system - Source system doCriInnt identifier - Source system related document identifier
37、 - Highest revision, change level, and date in the document - Date of issue of the latest change to the document - Character string identifying the destination system - Destination system document identifier - Destination system related document identifier - Date of transfer - Delivery accounting ch
38、aracter string (e.g., CDRLs, contract numbers) - Filecount - Title security label - Document security label - Document type - Document title The Document Declaration File shall contain “high-level“ information about each of the technical publications which are contained on the interchange media. Thi
39、s information ir intended to be absorbed into technical data repository library systems for the purpose of storing and retrieving the digitized technical publication. Within this Specification, the “delivery accounting character string“ record (dlvacc:) is further defined to provide additional requi
40、red data elements for technical publications. MIL-STD- 184A states that this record is a free form record which can pass additional information as further specified. Details regarding data elements to be contained in the Document Declaration File are discussed in Appendix A of this Specification. Th
41、is Specification adds additional data elements for the National Stock Number, Issuing Activity, Contracts Deliverable Requirements List (CDRL) number, Contract Number, system/equipment type to which document refers, security, volume/part, and a schema for relating this document to other documents (i
42、ncluding change pages). 3-3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-3.4 Data Files MIL-STD- 1840A standardizes the interchange of several different types of data files (e.g., SGML-tagged ASCII text, CGM, IGES, raster, PDL). MIL-STD-1840A stat
43、es that each data file shall have identifying header records. These header records provide some (but not all) data elements which are required for interactive storage and retrieval of the file. This Specification defines the data file header records in greater detail than MIL-STD-1840A. Specifically
44、, the “notes“ record (notes:) has been extended to contain additional data elements for the information content conveyed in the data file. The indexing information in the data file header records is intended to be assimilated in the master library. This Specification assumes that the technical publi
45、cation to be interchanged will be comprised of a cost effective blend of intelligent data files (Le., SGML-tagged ASCII text and entity graphics) and non-intelligent data files (Le., raster images). This Specification can accommodate virtually any ratio of intelligent to non-intelligent data files.
46、3.4.1 Textual Data Filet. MIL-ST-1840A provides for the interchange of SGML-tagged ASCII text data files. The basic DOD SGML tagging set is defined in MIL-M-28001. Sections of the technical publication tobe intelligently xanmsd will be identified in individual contract delivery orders or by user req
47、uest in the case of interchange between Government activities. Thus, the entire document or a critical minimum number of defined sections and pages may be intelligently scanned (through optical character recognition and raster-to-vector conversion). For sections and pages which are intelligently sca
48、nned, this Specification requires that they undergo rigorous quality assurance tests to ensure 100-percent accuracy. To permit user-friendly interactive technical information retrieval, display, and print-on-demand, this Specification requires that a critical minimum number of technical publication
49、sections be iritelligently scartried arid SGML-Lagged. At il minirviuiii, seclioris of the technical publicalion which shall be intelligently scanned will include: - the Table of Contents - the List of Illustrations - the List of Tables - the Technical Manual Index (if the technical manual has one) Additionally, if the document to be transmitted is change material only, this Specification requires that the “Instruction Sheet“ also be intelligently scanne
