Overview
ISO/IEC 8613-8:1994 - part of the Open Document Architecture (ODA) series - defines the geometric graphics content architectures and associated interchange format for ODA documents. This second edition (1994) replaces the 1989 edition and is intended to support reliable document interchange by data communication or media exchange. The standard enables both faithful presentation (as the originator intended) and processing (editing, reformatting) of geometric graphics embedded in documents.
Key topics
- Content architecture definition: formal description of a geometric graphics content architecture that integrates with the ODA document structure (ISO/IEC 8613 series).
- Content architecture classes: support for formatted, processable, and formatted-processable content to enable either presentation, processing, or both.
- Presentation attributes: shared and logical presentation attributes that govern how geometric graphics are displayed (orientation, defaults, picture dimensions, colour spaces).
- Positioning, layout and imaging: rules for positioning geometric graphics within basic layout objects, content layout process, and imaging procedures used to render graphics.
- Coding and data types: representation of coding attributes and geometric graphics data types, including references to CGM concepts and individual CGM elements.
- Interoperability interfaces: definitions that allow use of ISO/IEC 8632 (CGM) content within ODA documents and interaction with the document architecture (ISO/IEC 8613-2).
- Ancillary specifications: annexes summarizing ASN.1 object identifiers, CGM vs. character primitive differences, and an SGML representation for geometric graphics attributes in ODL.
- Conformance & testing: provisions and changes introduced in the 1994 edition (e.g., alternative representations, colour handling, conformance testing annex).
Applications and who uses it
ISO/IEC 8613-8:1994 is relevant to:
- Document processing software vendors implementing ODA interchange and mixed-content documents (text + graphics).
- Systems integrators and archivists needing standard-compliant interchange formats for long-term storage or cross-platform exchange.
- Government, legal and publishing organizations requiring reliable presentation and processability of geometric diagrams, technical drawings, forms and reports.
- Standards implementers and test labs creating conformance tests or translators between CGM (ISO/IEC 8632) and ODA.
Practical benefits include interoperable geometric graphics exchange, consistent rendering across platforms, and support for editable graphics in standardized document interchange.
