Overview
ISO/IEC 8613-5:1994 - Open Document Interchange Format (ODIF) - specifies the data-stream format and representation rules for interchanging documents structured according to ITU‑T Rec. T.412 / ISO/IEC 8613-2 (Open Document Architecture, ODA). Its aim is to enable reliable document interchange so recipients can either present documents as intended by the originator or process them (editing, reformatting, archiving). Typical document types covered include memoranda, letters, invoices, forms and reports, potentially containing pictures, tables, raster graphics and geometric graphics.
Key topics and technical requirements
- Interchange format classes - definitions of Format Class A and Class B for different interchange requirements.
- Descriptors and text units - metadata and structural units used to describe document constituents.
- Interchange data elements - canonical elements that make up the ODIF data stream.
- Document Profile descriptor - profile mechanism for indicating capabilities and expected processing behavior.
- Identifiers and expressions - naming and expression rules used throughout exchanged documents.
- Layout, logical and style descriptors - representation of visual layout, logical document structure and style inheritance.
- Default value lists, colour and protected part descriptors - default rendering values, color attributes and mechanisms to mark protected regions.
- ASN.1 encoding and cryptographic techniques - use of ASN.1 for encoding parts of the stream and support for enciphered/sealed information to protect content.
- Open Document Language (ODL) and SDIF - guidance on ODL representations, SGML constructs and use of Structured Document Interchange Format (SDIF).
- Annexes - coded representation, object identifier listings, example documents and canonical encoding guidance for implementers.
Practical applications and users
ISO/IEC 8613-5:1994 is relevant for:
- Software vendors implementing ODA/ODIF import-export, editors and converters.
- Document management and archiving systems requiring long-term, platform-independent document interchange and preservation.
- Interoperability engineers and standards implementers building cross-platform document workflows.
- Government and enterprise IT that exchange official forms, invoices and reports between heterogeneous systems.
- Archivists and digital preservation specialists who need precise, standardised encodings to retain presentation fidelity and editability.
Benefits include improved interoperability, preservation of layout and semantics, and mechanisms for secure interchange (enciphered/sealed content).
