Project Structure

mf uses .mf/ directory for its data:

.mf/
  paper_db.json           # Paper metadata database
  projects_db.json        # Project overrides and settings
  series_db.json          # Series metadata and sync state
  config.yaml             # Configuration
  cache/
    projects.json         # GitHub API cache (gitignored)
  backups/
    papers/               # Paper database backups
    projects/             # Projects database backups
    series/               # Series database backups

Key Concepts

Paper Database

Papers are tracked in paper_db.json with metadata like title, abstract, authors, tags, and source tracking (for LaTeX processing).

Project Database

Projects have two layers:

1. Cache (cache/projects.json) - GitHub API data, auto-refreshed
2. Overrides (projects_db.json) - Manual metadata like featured, hide, rich_project

Rich Projects

Projects marked rich_project: true get branch bundles with subsections:

• content/projects/<slug>/_index.md (main page)
• content/projects/<slug>/docs/_index.md
• content/projects/<slug>/tutorials/_index.md
• etc.

Series Database

Series are thematic collections of posts tracked in series_db.json. Series can:

• Sync posts from external source repositories
• Track associations to papers, media, and external links
• Have landing pages in content/series/<slug>/_index.md

Series with source_dir configured can sync posts bidirectionally:

mf series sync stepanov           # Pull from ~/github/alpha/stepanov
mf series sync stepanov --push    # Push to source repo

Content Linking

Use linked_project taxonomy (NOT projects) to link posts to projects:

# In post front matter
linked_project:
  - "likelihood.model"
  - "algebraic.mle"

Use series field to add posts to a series:

# In post front matter
series:
  - "stepanov"
  - "the-long-echo"

Analytics & Insights

The analytics commands help understand content-project relationships:

• mf analytics summary - Get a complete overview of your site's content relationships
• mf analytics gaps - Find projects that need more content coverage
• mf analytics suggestions - Discover content that mentions projects but doesn't link to them

Use analytics when you want to:

• Identify projects that lack documentation/posts
• Find opportunities to link existing content to projects
• Understand tag usage patterns and content velocity

Database Integrity

The integrity commands ensure database consistency:

• mf integrity check - Validates all databases for consistency issues
• mf integrity fix - Auto-fixes safe issues (stale cache, orphaned sync state)
• mf integrity orphans - Finds database entries without content files

Run mf integrity check periodically (e.g., weekly) to catch issues early. Common issues:

• Cache entries for deleted projects
• Sync state referencing removed posts
• Missing content files for database entries

Extended Content Audit

The extended audit system provides pluggable content quality checks:

mf content audit --list-checks    # Show all available checks
mf content audit --extended       # Run all extended checks
mf content audit --check required_fields --severity error

Available checks include:

• required_fields - Validates required front matter
• date_format - Checks date field formats
• stale_drafts - Finds drafts older than threshold
• And more (use --list-checks to see all)

Tips

1. Always use --dry-run first to preview changes
2. Run mf backup status to check backup health
3. Run mf integrity check periodically to catch database issues
4. Use mf analytics gaps to find content opportunities
5. Use slugs not paths in taxonomy fields
6. Validate before committing: hugo --gc --minify
