One of the reasons why modeled data is a powerful advancement is that it makes processing of such data easier. It allows for programmability and automation. When much of the networking data is CLI-based, the operational and configuration data from network devices is mostly hand-crafted. As a result, there has to be a lot of screen-scraping and manual testing to process such data. With the advent of modeled data, which could be modeled using a language like YANG, it can be easily processed by automated programs.
