How does the Narada Purana define the Ovi meter that Shri Mahipati used in his works?

The provided source material from Chapter 0 does not establish a link between the Narada Purana and the definition of the Ovi meter. The text mentions two separate facts: first, that the service of writing a Guru's biography is referenced in the Narada Purana, which proves its ancient origins. Second, it states that the renowned poet Maharaj Shri Mahipati wrote his great works in the Marathi Ovi meter. There is no information within these chunks to suggest that the Narada Purana defines or provides any details about the Ovi meter itself.
