Which schema.org type should be used for a topic?

[DevMakoto]

Neither Article or Blog seems to fit for a forum with topics and discussions. Or is Article considered for any generic post or comment?

for example, this would be fine?

Code: Select all

<script type="application/ld+json">
// <![CDATA[
{
	"@context":"http://schema.org",
	"@type":"DiscussionForumPosting",
	"headline":"Topic Title",
	"datePublished": "2016-03-18",
	"image": "url logo forum"
}
// ]]>
</script>
