Translations of this page:

We’re in the process of updating the documentation for Zotero 5.0. Some documentation may be outdated in the meantime. Thanks for your understanding.

This page describes the situation for Zotero 1.0, and is heavily outdated.

Most of the files listed below are contained within the zotero.jar archive in the chrome directory. For more information on extracting and modifying such files, see Modifying Zotero Files.

Extension root

  • chrome.manifest
    • Registers chrome files
  • install.rdf
    • Used by the Firefox add-on system
  • license.txt
    • Educational Community License
  • scrapers.sql
    • SQL to initialize site translator and CSL style tables — bundled translators and styles may be overwritten during extension upgrades or updates from central repository, but the table definitions are stored within userdata.sql, so user-added rows are preserved.
  • system.sql
    • SQL to initialize system tables — data in these tables may be overwritten during upgrades. Modifying these tables to add new item types, etc., may seem like a good idea, but it quite likely is not.
  • userdata.sql
    • SQL to initialize user data tables — data in these tables is preserved during upgrades, and any schema changes require migration steps in schema.js.

chrome/content/zotero/

Main overlay, windows and dialogs

  • about.xul
    • The About Zotero dialog

  • include.js
    • Calls getService() on the Zotero XPCOM component and assigns the core JS object to the variable Zotero. XUL files that aren't in the global scope need to include this file to gain access to the Zotero object:
      <script src="chrome://zotero/content/include.js"/>
  • itemPane.js
    • Display and editing logic for the metadata pane
  • itemPane.xul
    • Included from overlay.xul — creates the metadata pane on the right
  • note.js
    • Logic for standalone note window
  • note.xul
    • Standalone note window — note itself is created in the noteeditor.xml binding
  • overlay.js
    • Logic for the main Zotero overlay, including actions for many of the primary UI elements
  • overlay.xul
    • The main Zotero overlay on the browser window — this creates the Zotero pane and specifies actions for most of its UI elements.
  • preferences.js

    • The preferences window
  • progressWindow.xul
  • searchDialog.js

    • Used by the See Also box

    • Implements nsITreeView for the collections pane
  • data_access.js
    • Core data layer objects (e.g. Item, Collection, Tags, etc.)

  • search.js
    • Search engine logic (including saved searches)

chrome/skin/default/zotero/

Image and style files for the default skin

  • about.css
    • Styles for About Zotero dialog
  • addCitationDialog.css
  • overlay.css
    • Styles for elements in the main browser overlay
  • zotero.css
    • Main style file — the distinction between this and overlay.css has become rather poorly defined, and the two files will likely be merged at some point (and/or separated into disparate files for the various UI sections).
  • *.png
    • Image files for UI elements

chrome/skin/default/zotero/bindings/

CSS for XBL bindings

  • tagselector.css

components/

  • zotero-autocomplete.js

  • zotero-service.js
    • The base XPCOM component, which provides access to the core JS object from privileged code in Firefox — mostly boilerplate, but new files in chrome/content/zotero/xpcom must be included here using loadSubScript().

defaults/preferences

  • zotero.js
    • Sets defaults for Zotero preferences — changes to existing defaults only take effect on new installs (though new defaults can be added at any time).
