Skill2 starsChanged 6 months agoMITView on GitHub

Validates a DITA 1.3 bookmap file against structural rules derived from the DITA 1.3 bookmap DTD. Use this skill when you need to check bookmap element order (title, bookmeta, frontmatter, chapter, part, appendix, backmatter), booktitle completeness, appendices vs appendix mixing, and chapter presence. Returns structured JSON with errors and warnings.

Overview

Validates a DITA 1.3 <bookmap> file and returns a JSON report.

Usage

python scripts/validate_bookmap.py path/to/bookmap.ditamap
cat bookmap.ditamap | python scripts/validate_bookmap.py -

Output schema

{
  "is_valid": true,
  "errors": [{ "element": "string", "rule": "string", "message": "string", "line": 0 }],
  "warnings": [{ "element": "string", "rule": "string", "message": "string", "line": 0 }]
}

Rules applied

See references/RULES.md for the full catalogue.

CategoryKey rules
RootMust be <bookmap>
OrderDTD order enforced: (title|booktitle)?, bookmeta?, frontmatter?, chapter*, part*, (appendices?|appendix*), backmatter?, reltable*
ChaptersAt least one <chapter> or <part> required
Booktitle<booktitle> must contain <mainbooktitle>
Appendix<appendices> and bare <appendix> must not be mixed

Common edge cases

  • A bookmap with only <part> elements (no bare <chapter>) is valid — parts are checked
  • <backmatter> before <chapter> → Error (order violation)
  • <booktitle> without <mainbooktitle> → Error

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
