Foreword
IS0 (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the
specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the
development of International Standards through technical committees established by the respective organization to deal with
particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other
international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work.
In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft
International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
International Standard ISO/IEC 14863 was prepared by ECMA (as Standard ECMA-208) and was adopted, under a special
“fast-track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval
by national bodies of IS0 and IEC.
Annexes A to C form an integral part of this International Standard. Annexes D and E are for information only.

Introduction
The System Independent Data Format Association (SIDF) was formed in early 1993 by a consortium of industries.
ECMA TC15 adopted the work of this committee in early 1994 and developed Standard ECMA-208 on the basis of the SIDF
specification.

INTERNATIONAL STANDARD OISO/IEC /IEC 14863:1996 (E)
Information technology - System-Independent Data Format (SIDF)
Section 1 - General
1 Scope
This International Standard specifies a logical format for information interchange and secondary data storage. The format
provides a System-Independent Data Format (SIDF) for the representation of primary file system information. This
information includes, among other things, data, attributes and characteristics. This International Standard specifies
-
the organization of the information on target media,
-
requirements for originating and receiving systems for the processing of the information.
2 Conformance
Conformance of Media Volumes
21 .
A Volume shall be in conformance with this International Standard if all information recorded on it meets the relevant
requirements of sections 2 and 3 for the level of partition claimed.
22 . Conformance of an originating system
An originating system shall be in conformance with this International Standard if it meets the requirements of 14.2.
23 . Conformance of a receiving system
A receiving system shall be in conformance with this International Standard if it meets the requirements of 14.3 for the
Level of conformance claimed.
3 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this International
Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to
agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent

4 Definitions
For the purposes of this International Standard, the following definitions apply.
41 l Blank Space: Either one or more NULL Fields, or a BLANK SPACE Field Table.
42 Buffer: A set of adjacent sectors, which are logically related A common use of buffers is to encapsulate subsets of
fiie set data so that it can be treated as a whole.
43 . byte: A string of eight binary digits operated upon as a unit.
44 . Byte Sequence: An ordered set of bytes.
. Field: The basic logical grouping of data.
46 a Field Identifier (FID): A Byte Sequence which identifies a Field.
47 Field Table: A set of logically associated Fields.
representation of a single primary file
48 . File: A collection of data that is stored as a single unit. A File contains a
system entity, such as a Source directory, file, data base object, or data base.
49 0 file mark: A sector containing a control block used as a delimiter to facilitate positioning, as defined by the
relevant standard for recording.
Note 1 - Some media may not support file marks.
4.10 File Set: A set of associated Files, sourced from a single Source, recorded within a Volume Set.
4.11 Interleaved File Sets: Two or more File Sets are interleaved if any part of at least one is recorded between any
parts of another.
4.12 Iterated Field Set: A sequence of one or more Fields, which may be repeated within a Field Table.
4.13 operating system: The software which controls the file system of the Source.
4.14 originating system: An information processing system which can create a File Set in a Volume Set for the
purpose of data interchange with another system.
4.15 Relative Byte Position: Indicates the byte position in a number.
4.16 receiving system: An information processing system which can process a File Set of a Volume Set which has
been created by another system for the purpose of data interchange.

Set for secondary storage. The name of the Source is specified for the File Set, and is not included in the Source path
information of the individual Files.
4.20 standard for recording: A standard that specifies the recording method and the addressing method for the
information recorded on a medium.
