Current Review Formats

There have been several efforts to define data formats for posting "reviews" of products, services etc. on the Web.

This page serves to document the current list of review schemas, formats, and efforts as background for the design of a simple reviews microformat. -Tantek

Notes

Notice that author appears several times in the lists below, and that it sometimes refers to the author of the review, and other times to the author of the book being reviewed. A parenthetical will be used to distinguish them now.

Previous Schemas and Formats

Generic to any kind of review

RVW

  • http://www.pmbrowser.info/rvw/0.2/
  • variants for embedding in Atom, RSS2, RSS1, RDF
  • apparent schema
    • author of review
    • content of review
    • creator of work
      • example: book author, movie director
    • percentage score rating
    • multiple identifiers
      • example: ISBN, ASIN, UPC, LOC
    • link to purchase
  • appears to be loosely connected with the term "!OpenReviews" (has also referred to other efforts) which itself appears to be yet another OpenBlahBlah buzzword with no substance behind it (AKA placeholder term).

Google Base Formats

Google Base provided examples of uploading reviews in several formats. They provided sample files to be used as a template for creating your own files to upload to Google Base. They provided samples in the following formats: txt, RSS 1.0, RSS 2.0, Atom 0.3, Atom 1.0. In all cases, they share the same basic vocabulary:

  • vocabulary:
    • author
    • description
