Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0
member bodies). The work of preparing International Standards is normally carried out through IS0 technical
committees. Each member body interested in a subject for which a technical commjttee 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. IS0 collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to the member bodies for
approval before their acceptance as International Standards by the IS0 Codncil. They are approved in accordance
with IS0 procedures requiring at least 75% approval by the member bodies voting.
International Standard IS0 861 3-5 was prepared by Technical Committee ISO/TC 97, information processing
systems.
At present, IS0 8613 consists of seven parts:
- part 1, Introduction and general principles;
- part 2, Document structures;
- part 4, Document profile;
- part 5, Office document interchange format (ODIF);
- part 6, Character content architectures;
- part 7, Raster graphics content architectures;
- part 8, Geometric graphics content architectures.
NOTE - At present, there is no part 3.
Further parts may be added to this International Standard.
Development of this International Standard has been in parallel with:
- ECMA 101 : 1985, Office document architecture;
- CClTT Recommendation T.73 (1 984) : Document interchange protocol for the telematic services;
- CClTT Recommendations in the T.410 series (1988) : Open Document Architecture (ODA) and
interchange Format.
This part contains six annexes:
- annex A (informative): Coded representation;
- annex B (normative): Application class tag assignments;
- annex C (informative): Summary of object identifiers;
- annex D (informative): Examples;
- annex E (normative): Office Document Language (ODL);

Part 5 :
Office Document Interchange Format (OD1 F)
@I Scope
The purpose of IS0 861 3 is to facilitate the interchange of documents.
In the context of IS0 8613, documents are considered to be items such as memoranda, letters, invoices, forms
and reports, which may include pictures and tabular material. The content elements used within the documents
may include graphic characters, geometric graphics elements and raster graphics elements, all potentially within
one document.
NOTE - IS0 8613 is designed to allow for extensions, including typographical features, colour, spreadsheets and
additional types of content such as sound.
IS0 8613 applies to the interchange of documents by means of data communications or the exchange of storage
media.
IS0 8613 provides for the interchange of documents for either or both of the following purposes:
- to allow presentation as intended by the originator;
- to allow processing such as editing and reformatting.
@The composition of a document in interchange can take several forms:
- formatted form, allowing presentation of the document;
- processable form, allowing processing of the document;
- formatted processable form, allowing both presentation and processing.
IS0 861 3 also provides for the interchange of ODA information structures used for the processing of interchanged
documents.
Furthermore, IS0 8613 allows for the interchange of documents containing one or more different types of content
such as character text, images, graphics and sound.
This part of IS0 8613 defines
- the format of the data stream used to interchange documents structured in accordance with IS0 8613-2;
- the representation of the constituents which may appear in an interchanged document.
NOTES
1 This part of IS0 8613 does not specify the coded representation of content elements.
2 Data formats for presentation attributes and coding attributes are defined in other parts of IS0 8613.

4 Document representations
A document structured in accordance with IS0 8613 is represented for interchange by either the Office Document
Interchange Format (ODIF), or the Office Document Language (ODL) in conjunction with the SGML Document
Interchange Format (SDIF). The ODlF and ODLEDIF representations are technically equivalent; a document can
be transformed from one to the other without loss of information about the document constituents and attributes.
NOTE - Both data structure (ODIF) and language (ODL) representations have been standardized in order to meet the
document representation requirements of distinct application environments. ODIF, being a data structure specified using
ASN.l, is particularly intended for use in an OS1 environment. ODL is particularly appropriate for systems that share
information through marked-up text files, especially where human users can access the markup directly.
4.1 ODlF
ODlF is an abstract data syntax in which the constituents and attributes of the document are represented by a
hierarchy of data structures and data items, specified using the abstract syntax notation ASN.l defined in
IS0 8824.
The coded representation of each data structure or data item is obtained by applying a set of encoding rules.
’a ODlF is specified in clause 5.
NOTE - ASN.l is a formal description method that allows data types relevant to an application to be specified
in terms of other data types, including basic data types such as “integer” and “octet string” which are defined
in IS0 8824 itself. Basic encoding rules for ASN.1 are defined in IS0 8825 and are summarized in annex A.
4.2 ODL and SDIF
ODL is a language in which the constituents and attributes of the document are identified by descriptive tags, and
are grouped into one or more storage entities (e.g. files) as the user may require.
For interchange, each ODL entity is represented as a single data structure or data item, specified using ASN.1, in
a data stream constructed according to the SGML Document Interchange Format defined in IS0 9069.
ODL is specified in annex E (normative).
NOTE - ODL is an SGML application conforming to IS0 8879.
Office Document Interchange Format (ODIF)

5.1 General description
A document structured in accordance with IS0 8613 is represented by a data stream consisting of one or more
data structures of the following types:
- document profile descriptor;
- layout object descriptor;
- layout object class descriptor;
- logical object descriptor;
- logical oblect class descriptor;
- presentation style descriptor;
- layout style descriptor;
- text unit.
3

---------------------- Page: 7 ----------------------
IS0 8613-5 : 1989 (E)
These data structures are called interchange data elements. Within a data stream, the interchange data elements
are ordered in accordance with certain rules which are specified below. This part of IS0 8613 defines two such
sets of rules; they are called interchange format class A and interchange format class B.
Which of these sets of rules applies to a given data stream is indicated in the document profile descriptor. In all
cases, a data stream contains one and only one document profile descriptor which is always the first interchange
data element in the data stream. The document profile descriptor may be the only data structure in the data
stream.
When an ODlF data stream is used as part of an ASN.l external data type, the abstract syntax shall be formed by
an ASN.1 SEQUENCE-OF type referencing the Interchange-Data-Element type; the encoding of the data value
shall consist of an integral number of octets, formed by applying the ASN.1 basic encoding rules; and the value of
the associated ASN.l object identifier shall be { 2 8 O O }.
NOTE - The manner of incorporating the interchange data elements, or the external data type, in an application protocol or
the manner of mapping them on service data units (in an OS1 environment) is not defined by this part of IS0 8613.
5.2 Interchange format class A
According to interchange format class A, a data stream consists of one document profile descriptor and, optionally,
one or more interchange data elements of the following types:
- layout object descriptor;
- layout object class descriptor;
- logical object descriptor;
- logical object class descriptor;
- presentation style descriptor;
- layout style descriptor;
- text unit.
The order of the interchange data elements is as follows:
a) document profile descriptor;
b) layout object class descriptors;
c) logical object class descriptors;
d) text units representing generic content portions;
e) presentation style descriptors;
f) layout style descriptors;
g) layout object descriptors;
h) logical object descriptors;
i) text units representing specific content portions.
Within each of the groups of layout object descriptors and logical object descriptors, the order of the descriptors is
equal to the sequential order defined in IS0 8613-2.
If the data stream contains layout object descriptors, the text units representing specific content portions are
ordered according to the sequential layout order; otherwise, they are ordered accord ng to the sequential logical
order.
Within each of the other groups of interchange data elements, the order is arbitrary.

---------------------- Page: 8 ----------------------
IS0 8613-5 : 1989 (E)
5.3 Interchange format class B
According to interchange format class B, a data stream consists of one document profile descriptor and, optionally,
one or more interchange data elements of the following types:
- layout object descriptor;
- layout object class descriptor;
- presentation style descriptor;
- text unit.
Interchange format class B can be used only to represent documents that do not contain any specific or generic
logical structure, i.e. documents that conform to the formatted document architecture class.
The order of the interchange data elements is as follows:
a) document profile descriptor;
b) layout object class descriptors and associated text units;
c) presentation style descriptors;
d) layout object descriptors and associated text units.
).
Within the group of layout object class descriptors and associated text units, the order is such that a group of
descriptors that have identical identifiers, except for the last number in each identifier, follow each other in the data
stream without any other descriptor between them. However, each descriptor of an object class for a basic layout
object is followed immediately by the associated text units.
Within the group of layout object descriptors and associated text units, the order of the descriptors is equal to the.
sequential order defined in IS0 8613-2. However, each descriptor of a basic layout object is followed immediately
by the associated text units.
Within the group of presentation style descriptors, the order is arbitrary.
5.4 Descriptors and text units
A document profile descriptor, layout object descriptor, layout object class descriptor, logical object descriptor,
logical object class descriptor, presentation style descriptor or layout style descriptor consists of simple and
composite data items representing the attributes of the constituent concerned.
The document profile, each object class, each style and each object is represented by one descriptor.
A text unit consists of two parts:
a) an attribute field, i.e. a data structure consisting of simple and composite data items representing the
attributes of the content portion concerned;
b) an information field, i.e. a data structure that is either a data item or a set of data items representing the
content elements making up the content portion concerned.
Each content portion is represented by one text unit.
The data formats of the interchange data elements are specified in 5.5 to 5.12, using the abstract syntax notation
ASN.l defined in IS0 8824.
NOTE - 5.5 to 5.12 by themselves do not completely define the data stream format; additional rules are specified in 5.1 to
5.4 of this part and in other parts of IS0 8613. For example, the keyword OPTIONAL merely indicates that a particular data
structure or data item is not part of every instance of the containing data structure; the conditions controlling the presence
or absence of the data structure or data item are specified in part 2 or part 4.
