| Term                           | Description                                                                                                                                     |
| ------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------- |
| **AST (Abstract Syntax Tree)** | Pandoc’s internal structured representation of a document. Lua filters operate on the AST before rendering to a target format.                  |
| **Bibliography**               | A `.bib` file (e.g., Zotero export) used by Pandoc with `citeproc` to generate formatted citations and reference lists.                         |
| **Callout**                    | A styled block (e.g., `[!warning]`) transformed by Lua filters into format-specific output such as LaTeX environments or HTML `<div>` elements. |
| **Defaults File (YAML)**       | A Pandoc configuration file defining output format, filters, metadata, and rendering options (e.g., `pdf.yaml`, `html.yaml`).                   |
| **DOCX**                       | Microsoft Word document format generated by Pandoc; styling is controlled via a `reference.docx` file.                                          |
| **Filter (Lua)**               | A script that modifies Pandoc’s AST before rendering. Used in this workflow for callouts and other structural transformations.                  |
| **Frontmatter**                | Format-specific content inserted before the main body (e.g., `frontmatter.tex`, `frontmatter.html`, `frontmatter-docx.md`).                     |
| **HTML**                       | Web output format generated by Pandoc, typically styled via CSS and supporting interactive features.                                            |
| **LaTeX**                      | Typesetting system used for high-quality PDF generation via XeLaTeX in this workflow.                                                           |
| **Lua Filter**                 | A lightweight scripting extension used by Pandoc to customize document transformations programmatically.                                        |
| **Makefile**                   | Automation script orchestrating the build pipeline for PDF, HTML, DOCX, ODT, and Markdown outputs.                                              |
| **Markdown**                   | Plain-text markup language serving as the source format for all outputs in the workflow.                                                        |
| **Metadata**                   | Key–value pairs (e.g., `metadata.yaml`) defining title, author, license, version, and other document variables.                                 |
| **ODT**                        | OpenDocument Text format used by LibreOffice; similar to DOCX but open-standard.                                                                |
| **Pandoc**                     | Universal document converter used to transform Markdown into PDF, HTML, DOCX, ODT, EPUB, and more.                                              |
| **PDF**                        | Portable Document Format output produced via Pandoc + XeLaTeX.                                                                                  |
| **Reference Document**         | A DOCX or ODT file defining styles (fonts, headings, spacing) used when generating Word/LibreOffice outputs.                                    |
| **Resource Path**              | Directories Pandoc searches for images, diagrams, and other assets during rendering.                                                            |
| **Template**                   | A format-specific layout file (e.g., LaTeX template) used to control document structure beyond styling.                                         |
| **TOC (Table of Contents)**    | Automatically generated navigation structure controlled by `toc` and `toc-depth` options.                                                       |
| **XeLaTeX**                    | LaTeX engine used to generate PDFs with modern font support (via `fontspec`).                                                                   |
| **Zotero**                     | Reference manager used to generate `.bib` files for citation processing with Pandoc.                                                            |
