Code review comment for lp:~adiroiban/launchpad/bug-527728

= Bug 527728 =

It looks like the source_package is already exported in API (https://api.launchpad.net/+apidoc/#source_package).

To help with translation reporting tasks (https://dev.launchpad.net/Translations/Specs/ReportingAPI) it would be nice to also have the component name for a source package.

== Proposed fix ==
Add compoment_name in the list of exported attributes for ISourcePackage

== Pre-implementation notes ==
Sinzui suggest exporting the compoment_name as latest_published_component_name, since this is the flattening export for latest_published_component

== Implementation details ==

I don't know how to get rid of those lazr.restful lint warning.
Any suggestion is much appreciated.

== Tests ==
lp-test -t source-package.txt

== Demo and Q/A ==
The Ubuntu Hoary source package is exported via API at:
https://launchpad.dev/api/beta/ubuntu/hoary/+source/evolution

The list of attributes should include the „component_name” and it should match the component name displayed at https://launchpad.dev/ubuntu/lucid/+source/evolution
