I'm looking for a solution. I've been trying to hunt it down for a while now and it's getting to the point where I'm running out of ideas. So, hail mary, let's ask hubski.
Right now, every platform I've seen that manages content documentation does so at the document level - I can write a document on how to start selling on Amazon, another on how to sell on eBay, another on rakuten, etc.
In these documents the first step would always be the same - get a spreadsheet with your inventory data. But imagine that step changed - we use XML instead of spreadsheets now. You would have to go through and make the changes 3 times - super annoying. Especially if the rakuten one was written 5 years ago and you forgot about it - then it's just forever out of date.
In technical writing there's a thing called component content management which uses DITA structured data to tackle this problem. You make little stubs, short paragraphs of information, then use the stubs to make articles. If you update the stub, the information is updated in every article.
The problem is that CCM and DITA are complicated - way more complicated than a CMS like wordpress. If I wanted to implement a system like CCM, I would lose 95% of my content creators to the complexity of the system.
So, the question - does anyone know of a content management system that allows for component content management, but also has an easy interface?
