〜というのは〜ことだ

… means… (defining, explaining a term)machine translation

FormationWord/phrase being explained + というのは + explanation + (という)ことだ/という意味だ

〜というのは〜ことだ is the DEFINITION sentence frame: name a word, then explain what it means. 「花見」というのは、桜を見ながら楽しむことです ("hanami" means having a good time while viewing cherry blossoms). This is a pattern you will use constantly when asking about and explaining new words.

Choose the sentence ending to match the explanation: end with ことだ when the explanation is an action or event (〜することです); end with という意味だ when you want to say outright "it means" — especially when explaining signs or abbreviations: 「立入禁止」というのは、入ってはいけないという意味です.

In casual conversation, というのは gets shortened to って — the contraction you met at N4. As for つまり: つまり slips into the middle of a sentence to restate an idea another way, with no fixed frame; というのは〜ことだ is a complete definition sentence, the standard way to answer the question 「〜って何ですか」.
