Example: Generating NIDs |
|||
Consider the following new document. The first paragraph can get any NID: First paragraph. (01)
Suppose you added a new paragraph. The first paragraph retains its NID, while the second paragraph gets a new, unique NID: First paragraph. (01) This is the second paragraph. (02) Now suppose you deleted the second paragraph, and then added a new one. Because the second paragraph was removed, its NID cannot be reused: First paragraph. (01) This is the third paragraph added. (03) |
