Frequently Asked Questions
What are the ASD S-Series specifications, and why are they crucial for aerospace?
The S-Series are documentation standards used primarily in demanding industrial sectors such as aerospace, defense, and complex systems.
They make it possible to structure, organize, and manage critical technical documentation (such as maintenance manuals, procedures, or specifications) according to strict rules, ensuring consistency, traceability, content reuse,
compliance with regulatory requirements.
These standards are often associated with environments where documentation must be precise, modular, and maintainable over the long term.
DITA XML vs. ASD S-Series: what’s the difference?
DITA XML is a modular and flexible standard for structuring technical content (topics, maps), ideal for reuse and multichannel publishing (PDF, HTML, etc.). It is suited to a variety of sectors (IT, industry, healthcare).
ASD S-Series is a sector-specific standard (aerospace, defense, space) that imposes strict rules to ensure compliance, traceability, and security for critical documentation (maintenance manuals, specifications).
In short:
- DITA = Flexibility + reuse.
