   Keeping your promises is what being an adult is all about.

3. 一度いちど引ひき受うけた仕事しごとを最後さいごまでやるのが、責任せきにんというものだ。

   Finishing a job you have taken on is what responsibility means.

When to use it

Use というものだ to state what something truly is or should be, as a general truth or the speaker's firm view, as in 困こまった時ときに助たすけるのが友情ゆうじょうというものだ (helping in hard times is what friendship is). It is also used to judge a situation: それは無理むりというものだ (that is simply unreasonable).

Nuance

Neutral to slightly formal, with a tone of conviction, sometimes of criticism. It sounds like the speaker is stating common sense. It is not used for simple facts or the speaker's personal habits.

Compare

ものだ alone gives advice or a general tendency (人ひと). というものだ defines what something really is (約束やくそくを守まもるのが大人おとなというものだ). というものではない, the negative, means "it is not necessarily the case" and corrects a common belief: 高たかければいいというものではない.

Tip: Read it as "that is what X is all about". If you can add "is all about" in English, というものだ probably fits.
