I don't have access to the specific context about "Category:Country data templates" that you're referring to. Without being able to see the actual Wikimedia category page content you want me to base this on, I cannot write an accurate overview that meets your requirement to base it "ONLY on this context" and not invent facts. If you could share the text or description from that Wikimedia category page, I'd be happy to create the 2-sentence overview for you.
