When using go-ap/jsonld, to extend the context by a term use:

jsonld.WithContext(
	jsonld.Context{
		{IRI: jsonld.IRI(vocab.ActivityBaseURI)},
		{Term: jsonld.Term("Hashtag"), IRI: jsonld.IRI("https://www.w3.org/ns/activitystreams#Hashtag")},
	},
)

Instead of:

var ApEncoder = jsonld.WithContext(
	jsonld.IRI(vocab.ActivityBaseURI),
	jsonld.Context{
		{Term: jsonld.Term("Hashtag"), IRI: jsonld.IRI("https://www.w3.org/ns/activitystreams#Hashtag")},
	},
)

The latter ignores the terms.

My blog now (hopefully) supports #hashtags on #ActivityPub. Please like this post if you found this via a hashtag.

#testing

#

again testing hashtags with #activitypub #mastodon format.

#

I'm not sure if this note will show up on hashtags. They are added to the #ActivityPub object, but is this sufficient for #Mastodon?

Please react to this if you saw this note due to its hashtag!

#fediverse #testing

#

owl-blogs now supports replies to entries. The content of the reply is added to the bottom of the post, similar to comments.

Another test note

I can now process likes on my blog notes via #ActivityPub
