I am reading about the 5-star schema for Open data. I noticed that the data ranked with three stars are CSV files while data ranked as two stars are like Excel documents. I wonder why is that?
Is excel less quality than CSV?
Is it because for excel we need a specific application to open it while we can process CSV easily using any text editor?
EditI have been reading about it and I found the followings: **I am not sure if this is correct or not**:
- The two-star-data is data that is formatted under a Close Format or Proprietary Format, which is a way of storing the data according to a specific encoding format that is either secret or not allowed to use in an open license.
- The three-star-data is data that is formatted under an Open format or Non-Proprietary Format, which is a way of storing the data according to a specific encoding format that is allowed to use by anyone.
Is that correct, please?
