There is interest and excitement building around the potential of knowledge graphs (“interlinked descriptions of entities [that] also encod[e] the semantics”) to drive content operations. I believe that knowledge graphs and content management systems (CMSs) that sit on top of knowledge graphs have a critical part to play, but I also have some concerns.
Since 2013, Scriptorium has had a very informal content maturity model:
Crap on a page
Design consistency
Template-based content
Structured content
Content in a database
Each level is explained in Why is content strategy hard?
You need at least level 4 for efficient content ops, and many organizations need level 5. The basic difference between levels 4 and 5 is how you store the content. In theory, you can create structured content in text files (XML or other markup).
