## Objective
Create a proof-of-concept Draw.io plugin that exposes an RDF/XML export option,
register it so the editor can load it like built-in plugins, describe how to use
it, and document the engineering work.

## Repository analysis
* Located the plugin infrastructure under `src/main/webapp/plugins/` and reviewed
  existing samples (`svgdata.js`, `tags.js`, `anonymize.js`) to understand how
  actions are registered and menus are extended.
* Inspected `App.js` and `app.min.js` to learn how plugins are registered and
  exposed to the plug-in dialog via `App.pluginRegistry` and
  `App.publicPlugin`.
* Confirmed that production builds rely on the minified bundle by reading
  `index.html`, which meant registry updates had to land in both the source and
  minified versions.

## Implementation summary
1. **New plugin file** — Added `src/main/webapp/plugins/rdfexport.js` that
   registers an `exportRdfXml` action. The plugin:
   * Builds a new DOM document rooted at `<rdf:RDF>` with both the RDF and
     `example` namespaces declared.
   * Clones the editor's `<mxGraphModel>` tree using `createElementNS` so each
     element becomes an `example:*` node while all attributes/text nodes are
     preserved, using the element returned by `editorUi.editor.getGraphXml()`
     directly to avoid dropping the model from the export.
   * Wraps the cloned tree inside `<example:Diagram>` tagged with
     `rdf:about="urn:diagram:{pageId}"` and a human-readable title element.
   * Hooks into the **File → Export as** menu to surface the new action and uses
     `editorUi.saveData` to produce a `.rdf` download with MIME type
     `application/rdf+xml`.
2. **Registry updates** — Extended `App.pluginRegistry` / `App.publicPlugin` in
   both `App.js` and `app.min.js` with the `rdf` identifier so the plugin can be
   loaded via `?p=rdf` and appears in the plugin manager.
3. **User documentation** — Authored
   `docs/plugins/rdfexport/README.md` describing how to enable the plugin (URL
   parameter or plugin dialog) and what the exporter produces.
4. **Engineering log** — Recorded these steps in this report for future
   reference.

## Testing
* No automated test harness exists in this repository (no `package.json` or
  documented build scripts). The changes are isolated to a plugin and related
  documentation, so no commands were executed. Manual verification guidance is
  captured in the README.

## Follow-up ideas
* Expand the exporter to cover multi-page diagrams and embed richer RDF
  semantics instead of the current namespace-only clone.
* Add a round-trip smoke test that ensures the plugin action generates valid XML
  by parsing it before download when running in development mode.
