ITU Electronic Document Database Formats
When using ITU's electronic document databases, the term 'document'
can refer to many different kinds of electronic information resources:
e.g., simple text files, word processing files, formatted publications,
graphics, databases, spreadsheets or software in source code or
executable format. Some information resources are available in
several formats and languages. The format and language you choose
to retrieve depends on your preferences and the capabilities of
your computing/software environment.
You should, of course, make sure you have the capability to read a specific format before retrieving it. For example, almost all computing environments can read simple ASCII text files. However, if you wish to retrieve a document posted in Microsoft's Word for Windows format, you will require access to a corresponding version of this program or an appropriate filter into your word processing program. Likewise, if you wish to retrieve a document formatted as Postscript printer
output, you will require access to either a Postscript printer or a Postscript file viewer.
Listed below are the formats you may find on the ITU electronic
document database in alphabetical order. Following the format name in
parentheses is a shorthand notation that may be used sometimes to refer to
that format(s).
- ASCII
- Often the only format that different word processors have
in common is a line-oriented format using ASCII (7-bit) characters.
ASCII is used for documents that require very simple formatting
or for simple lists. If the ASCII version of a document is not
the original format, it is very like that it does not faithfully
represent the original document. For example, conversion from
a word processing package to ASCII results in loss of text and/or
formatting. ASCII can only be used for English texts. ASCII files
typically have the extension .txt
- C Source Code (CSOURCE)
- C language source code is in ASCII (7-bit) characters. C
files are ASCII format and typically have the extension .c
- Designer (DESIGNER3.1, DESIGNER 4.0)
- Designer is a vector graphics program running in the MS-Windows
environment. It is manufactured by Micrographx Inc. in Richardson,
Texas. Designer is a standard drawing package used at the ITU.
Designer graphic files are binary format and typically have the
file extension .drw or .dr4
- DOS Executable (DOSPROGRAM)
- A DOS executable is an executable program for the MS-DOS
environment. Some programs available on the ITU Document Store
are "self-unpacking". This means that executing the
program will automatically unpack several related files. DOS executables
are binary format and have the file extension .exe
- Excel 4.0 Spreadsheet (EXCEL4.0)
- These are Excel 4.0 spreadsheet files generated by Excel
running in the MS-Windows environment. Excel is manufactured by
Microsoft Corporation in Redmond, Washington. Excel spreadsheet
files are binary format and have the file extension .xls
- GIF
- GIF (Graphics Interchange Format) is a popular graphics format.
It is the main inline graphics format used with World Wide Web.
Most WWW browser can open GIF files directly.
- HTML
- HTML (Hypertext Markup Language) is a variation of SGML.
- JPEG
- JPEG is a graphics format. Some WWW browser can view inline
JPEG images.
- KODAK Photo CD Bitmap
- Koday Photo CD Bitmap is a raster graphics format.
- Macintosh Executable
- A program for the Macintosh computer.
- ODA/ODIF (ODIFQ112, ODIFFOD26, ODIFFOD36)
- Open Document Architecture (ODA) and Open Document Interchange
Format (ODIF) are ITU-T (formerly CCITT) Recommendations (T.410
series) also adopted by International Organization for Standardization
(ISO 8613). ODA is a modern, object-oriented document architecture
for the description of both the logical and layout structures
of a document. Examples of logical objects are abstracts, titles,
sections, paragraphs, figures, tables, etc. Examples of layout
objects are pages, columns, frames, etc. ODA provides for the
representation of documents in processable form, which allows
revision by a recipient, and formatted form, which allows the
precise specification of the document layout. ODA also supports
the transfer of documents in formatted processable form. ODIF
defines the data stream of the actual interchange format. With
ODA/ODIF, compliance with the standard is defined by document
application profiles (DAPs). ODIF files accessed through ITUDOC
correspond to the International Standard Profile ISP 11181 (also
known as FOD26). They have been converted to ODIF FOD26 from Rich
Text Format (RTF) by the Bull ODA Product Set (BOPS). ODIF files
are binary format and typically have the file extension .odf.

- PageMaker 5.0
- PageMaker is a document layout program.
- Postscript
- Postscript is a final form document - in other words, it
typically cannot be edited or revised. It can only be printed
or viewed on-screen. However, the Postscript form of a document
is typically identical to the ITU printed page form. Postscript
files are 7-bit ASCII and so can be transported between various
electronic mail systems (however, they are typically very large).
After you receive a Postscript file, you can copy it to your Postscript
laser printer for a printed version of the document. Note that
ITU documents are paginated for A4 paper size and so all text
may not fit on North American Letter size paper. If this causes
difficulty you may wish to obtain a public-domain Postscript file
viewer called Ghostscript. Ghostscript is available at many computer
sites around the world. Postscript files have the file extension
.ps
- PowerPoint files (POWERPOINT3.0)
- PowerPoint is a MS-Windows presentation graphics package
from Microsoft Corporation in Redmond, Washington. PowerPoint
files are binary format and have the file extension .ppt
- Rich Text Format (RTF)
- Microsoft Rich Text Format (RTF) is a standard form of encoding
for text and graphics interchange that can be used with different
microcomputers and operating systems. RTF can represent all objects
contained in ITU documents (e.g. multilingual text, footnotes,
headers, footers, symbol sets, tables, mathematical formulas,
geometric and raster graphics, font information, layout, structure
elements). A standard RTF file typically consists of only 7-bit
ASCII characters so it can be transported more easily between
various mail systems. RTF is currently one of the best methods
to exchange compound documents between different computing environments
(e.g., DOS/Windows, Macintosh, UNIX). RTF files are ASCII format
and have the file extension .rtf
- Sound Wave Files (SOUNDWAVE)
- Sound Wave files are in the format used by the Microsoft
Windows 3.1 environment. Sound Wave files are binary format and
have the file extension .wav
- Tagged Image File Format (TIFF)
- TIFF is a raster graphics format and typically has the file
extension .tif
- UNIX Compressed TAR (ZTAR)
- A common compression and archiving format for UNIX systems.
- Windows Bitmap (BMP)
- Windows Bitmap files are in the format created by the Microsoft
Windows 3.1 PaintBrush desktop accessory. MS-Windows Bitmap files
are binary format and have the file extension .bmp
- Windows Write (WRITE)
- Windows Write files are in the format created by the Microsoft
Windows 3.1 Write desktop accessory. Write files are binary format
and have the file extension .wri
- Word for Windows (WINWORD1.0, WINWORD 2.0, WINWORD 6.0)
- Word for Windows is the ITU's standard document processing
tool and therefore documents posted in this format represent the
ITU's full content and formatting. The version being used as of
October 1993 is Word for Windows Version 2.0. Word for Windows
files are BINARY format and typically have the extension .doc
- Word for Windows Templates (WINWORD1.0DOT, WINWORD2.0DOT, WINWORD6.0DOT)
- Word for Windows templates are used to provide standard formatting,
layout or macro programs for preparation of ITU documents. The
version being used as of October 1993 is Word for Windows Version
2.0. Word for Windows template files are BINARY format and typically
have the extension .dot
- WordPerfect (WORDPERFECT5.1)
- WordPerfect is a popular word processor available for several
computing platforms. WordPerfect files are BINARY format and typically
have the extension .doc
- ZIP Format (ZIP)
- PKZIP files are in the format created by the PKZIP file compression
and archiving program. This format is used to combine a set of
files into a single compressed binary file. A PKUNZIP program
is required to de-archive and uncompress files. PKZIP and PKUNZIP
are widely available on international computer networks or from:
