Comment 1 for bug 531261

Here is the list of attributes found both in IProductSeries and IDistroSeries.

Is it ok if I move them in ISeriesMixin and their implementation in SeriesMixin ?

Otherwise, are you happy with the changes from the current attached branch?

    name = exported(
        DistroSeriesNameField(
            title=_("Name"), required=True,
            description=_("The name of this series."),
            constraint=name_validator))

    status = exported(
        Choice(
            title=_("Status"), required=True,
            vocabulary=SeriesStatus))

    date_created = exported(
        Datetime(title=_("The date this series was registered.")))

    owner = exported(
        PublicPersonChoice(title=_("Owner"), vocabulary='ValidOwner'))

    driver = exported(
        Choice(
            title=_("Driver"),
            description=_(
                "The person or team responsible for decisions about features "
                "and bugs that will be targeted to this series of the "
                "distribution."),
            required=False, vocabulary='ValidPersonOrTeam'))

    title = exported(
        Title(
            title=_("Title"), required=True,
            description=_(
                "The title of this series. It should be distinctive "
                "and designed to look good at the top of a page.")))

    displayname = exported(
        TextLine(
            title=_('Display Name'),
            description=_('Display name, in this case we have removed the '
                          'underlying database field, and this attribute '
                          'just returns the name.')),
        exported_as='display_name')

    summary = exported(
        Summary(title=_("Summary"), required=True,
            description=_(
                "A brief summary of the highlights of this release. "
                "It should be no longer than a single paragraph, up "
                "to 200 words.")))

The following attributes, have the same interface, but their implementation is different as they depend of product or distribution. Maybe we can move them in IHasBugs, IHasDrivers ... etc

    packagings = Attribute("All of the Packaging entries for this "
        "distroseries.")

    specifications = Attribute("The specifications targeted to this "
        "series.")

    drivers = Attribute(
        'A list of the people or teams who are drivers for this series. '
        'This list is made up of any drivers or owners from this '
        'DistroSeries, and the Distribution to which it belong.')

    bug_supervisor = Attribute(
        'Currently just a reference to the Distribution bug supervisor.')

    security_contact = Attribute(
        'Currently just a reference to the Distribution security contact.')
