Ratings and reviews in software-center
To make software easier to choose in the Ubuntu Software Center, Launchpad should record ratings and reviews for applications and binary packages, submitted to it by users with an Ubuntu Single Sign-on account via the Launchpad API. There should also be a moderation system for speedy removal of inappropriate reviews.

- Star ratings,
- Writing reviews (summary, detail and rating).
- Reporting of reviews as innappropriate.
On the server-side, a review will need to be for:
- an application
- a version
- a distroseries (as even the same version in different series).
* How to avoid bad data - can we allow reviewers to create/contribute meta-data (categories, etc.). mpt: that's separate.
* Can we add a 'This was a helpful review'? Yes - needed.
* Can the reporting of innappropriate reviews not be abused? Yes, need thought as to, for example, requiring 2 reports before it is hidden and added to the moderation queue.
* Will reviews persist between application versions? Show reviews for the current version, but with access to reviews from previous versions.
* A downside here is that we may lose (hide) a "valuable" review that may actually still be perfectly relevant, just because of a version bump
* Reviews should also be sensitive to origin of the package, in case one "version" might come from different source (e.g. PPAs)
* Languages - we need to support multiple languages. What should our defaults be? Should the server serve English reviews if there are no native language reviews? (Proposal: if there are no localized reviews yet, show a note: "Be the first to add a <language> review!")
+ If we default to English when no native-language reviews, maybe show a button to "See all language reviews"
* Spam filtering on the server-side? Yes - we may need something. We will not linkify in comments (and may disallow links entirely).
* Will we be able to edit/update a review after adding it. Yes, for 10mins or so (otherwise the 'Was this review helpful' is incompatible).
* Would we be able to have special reviewers (OMG! Ubuntu!, arts technica)
* Using Karma or CoC for moderators? Proposal: not unless we have a simplified/
* API for other websites to show top reviews etc.
* Do we need licensing of the reviews? Using a default CC license?
* Evan would like to see metrics like bug-count, crashes, install count, delta between when a bug is reported to when it is fixed (help?)
* Initially mvo would like to limit reviews to commercial apps and distro apps, not random PPAs, but the infrastructure needs to support PPAs in the future.
* Should vendors be able to opt-out of reviews? (perhaps restricted to commercial apps/apps where we can know who the vendor is).
* Can we do something similar to the 'launchpad-
* Can Vendors/authors respond to reviews?
* Hooks to allow an application to provide in-app review ability? Maybe from an About dialog?
* If a user uses an application a lot, maybe pop up an invitation to review it
+ If we do this, would we end up with tens of thousands of reviews for a single app, which is not so useful?
+ What about command-line apps, such as "ls"? :)
+ Pop-ups should not interrupt the user's workflow
