I want to build an ECS-based web metaframework and CMS. Is this a new idea? If not, what are some existing implementations? I have very particular goals and constraints so I'm making it anyway but I was wondering if there's prior art to learn from.

My particular design parameters:
- first-class SSG support
- _simultaneously_ human-editable and machine-editable data files
- multiple data sources
- Linear performance of query system secondary to scaling because data changes rarely but there's a lot of it

Basically I want to co-edit a static site with a less tech-savvy friend, I want to do everything in text, she obviously needs an editor that makes invalid state very difficult to produce. I already have a text-based SSG that does a lot of things really well, so I'm basically inserting ECS as a middle layer to make the data easier to work with for the tools that will separate my co-editor from the storage and collaboration system, and to separate it better from the code. I'm going to all this effort because as I was thinking of a solution I realized that I bumped into this problem countless times and every time either the project died or I had to give up my own convenience for that of automation.

I see letters but they don't make sense...
