TW as PlantUML diagrams storage for sourcecodes and URL for generating

Hi, after some time I have question, may be too complex but …

Idea description: We have many many many many diagrams for architecture, concept modelling, etc. I am using PlantUML as platform to generate PNG/SVG and special tool to generate XMI for another architectural tools. Yes, I can use TW plantuml plugin(s), but i have idea that we store and update diagram as tiddlers and I can call it as generated images or URL with plantuml.com for generating URLs with images to use everywhere on internet.

My problems are:

  1. Plantuml plugins can store sourcecode but generates images without ALT description so its unaccessible and its not any way to determine if diagram renders correctly.
  2. I am not able to find any plugin which can generated encoded url for diagram (https://plantuml.com/plantuml/png/xxxxxxxxxxx) from tiddler content, so it is not possible to get publicly usable URL of diagrams.

Any ideas to do it?
