Would any of these be credited with Original Material By or whatever?

This is what the credits read.

"Based on the musical play EVITA, Lyrics by Tim Rice, Music by Andrew Lloyd Webber, Produced on Broadway by Robert Stigwood in association with David Land"

Currently in the profile I have only Tim Rice is credited with an OMB credit.

I agree with Hal.

Evita is entirely sung. The lyrics of the musical are called "the book". That is the writing credit for a musical play.

DVDP lists in the program that OMB is used for (book, poem, song, etc). In this context, an OMB for Tim Rice is appropriate.

Shouldn't Andrew Lloyd-Webber get an OMB too as he wrote the music for the "musical play"?

I understand what you are saying, but that isn't what the credit says.  For them to get an OMB credit, it should read, something like, "Based on the musical play EVITA, by Tim Rice and Andrew Lloyd Webber."

All we know from the credit is that the film was based on the musical play.  Nothing in that credit tells us who wrote the musical play.  For all we know, it was written by somebody else and these two just wrote music and lyrics.  (I am not saying that is the cast, just that the credits don't say otherwise.)

Just for arguments sake, if you were profiling the play itself, would you give any of these folks a "Writing" credit?

I would not, based on the actual credits. 

TR would get a songwriter credit; ALW would get a composer credit; the rest would get producer credits.

If it's not a "Writer" credit for the play, how can it be a "writer" credit (OMB is a "writer" credit) for the movie? 

Outside knowledge about "the lyrics of the musical are called a "book", and that is a "writing credit for the play" don;t really matter for DVDP.  we can only go by what the on-screen credit says.  None of those are "Writing" credits.

But that's not relevant, we're talking about an OMB credit here, not a writing credit.

I think I see where people's confusion is coming from. The credit:
"Based on the musical play EVITA, Lyrics by Tim Rice, Music by Andrew Lloyd Webber, Produced on Broadway by Robert Stigwood in association with David Land"
refers entirely to the play, not to the film.

And as the OMB credit only refers to "original material", it's not essential that they were originally given a writing credit or not.

OMB is a "writing" credit in that it is within the "Writing" section of the credits.

OMB typically means adapted from another medium...medium typically meaning written medium (I know...not always).

Of course it tells us who wrote the play - if anyone else was involved, don't you think they'd have been mentioned too?
Tim Rice wrote the words, Andrew Lloyd Webber wrote the music, nobody else wrote anything else.
