The two main data schemas for books are going to be either the MaRC family of formats for libraries (http://www.loc.gov/marc/bibliographic/) or the ONIX for Books standard for publishers, retailers and wholesalers (http://www.editeur.org/83/Overview/) - but note that these are technically compatible already (http://www.loc.gov/marc/onix2marc.html and http://www.editeur.org/96/ONIX-and-MARC21/).

The main difference would be that in MaRC, there may not be a recognisable "entity" for Person (the attributes will be scattered through the schema somewhere) whereas ONIX tries to keep all the related data about an author together (much more so in the new version 3.0).

Hope this helps.

The former seems to be more extensible, in that you can add more Person attributes as they become available. The latter seems easier for HTML authors to start to use, if they aren't already using microdata. Perhaps the question of which is "better" might be answered by considering the applications that will use the data, and the context in which the data is going to be published? Do you have a sense of either of those?
