The [[api-documentation:IBookmarkableContentType Plugin Type|IBookmarkableContentType]] interface provides support for bookmarking content.

Why should I make my content bookmarkable?

It can be important for users to save content. If you are creating a schedule users may want to return to this content and review it for changes.

Creating an IBookmarkableContentType plugin

[[api-documentation:IBookmarkableContentType Plugin Type|IBookmarkableContentType]] is defined in the Telligent.Evolution.Extensibility.Content.Version1 namespace of Telligent.Evolution.Core.dll.

It is important to note that one or more Core Services can be implemented in the same [[api-documentation:IContentType Plugin Type|IContentType]] class.

This interface is similar to the others, it requires you to define whether a user can bookmark or unbookmark content. It also should return if the content supports bookmarks. In this sample we arbitrarily selected the Read Group Members permission but any permission can be defined here.

public bool CanBookmark(Guid contentId, int userId)
{
    return CanUseBookmarks(contentId, userId);
}

public bool CanUnBookmark(Guid contentId, int userId)
{
    return CanUseBookmarks(contentId, userId);
}

public bool SupportsBookmarks
{
    get { return true; }
}

private bool CanUseBookmarks(Guid contentId, int userId)
{
    var content = LinksData.GetLink(contentId);
    if (content == null) { return false; }

    var read = new Guid("4F692E0C-9CAB-4d09-9126-684FAF41A085");
    var permission = Apis.Get<IPermissions>().Get(read, userId, content.ContentId, content.ContentTypeId);
    return permission.IsAllowed;
}

Here is the full sample.
