  • The first paragraph at https://en.wikipedia.org/wiki/Semi-structured_data answers your question. – axiom Jun 18 '15 at 11:11
  • What is there to "explain" about your XML example? – Wyzard Jun 18 '15 at 13:23

  • I have the same question. Maybe it's considered semi structured because you can add any tag to it and the tags ar not known in advance. So you can't imagine a table (like relational model) with specific columns in advance. – Michelle May 05 '22 at 15:00

Semi structure data is a set of documents on the web which contain hyperlinks to other document and it cannot be modeled in natural relational data model because the pattern of hyperlinks is not regular across documents.
