About

ActivityPub source implementation for Awakari. Actually, just another Fedivers server that follows specified publishers on behalf of a user.

Awakari is a service consuming public only updates from various sources and filters these for a user. The purpose is only to notify user in real time and provide a link to the source (e.g. post). If you don't want Awakari to follow you, just find it in a list of your followers and remove.

Conversion Schema

Specific (non "as is") attribute conversions:

Source Activity Attribute	Destination CloudEvent Attribute	Notes
actor.id	source
actor.name	subject	e.g. "John Doe"
published	time
content	<text data>
summary	<text data>	Prepends the existing text data (if any) with a line separator
type	action	e.g. "Create"
object.id	objecturl	only if object is link
object.type	object	e.g. "Note"
object.attachment.id	attachmenturl	only if attachment is link
object.attachment.url	attachmenturl	only if attachment is object
object.attachment.mediaType	attachmenttype	only if attachment is object
object.content	<text data>	Prepends the existing text data (if any) with a line separator
object.inReplyTo	inreplyto
object.location	latitude
object.location	longitude
object.startTime	starts
object.summary	<text data>	Prepends the existing text data (if any) with a line separator
object.image	imageurl

Notes:

• All other attributes (not mentioned in the table above) are been converted as is, e.g. "duration" -> "duration"

• Activity attribute may be an "object" without an activity type (verb, e.g. "Create"). Then it's also been converted as "object" in addition to the activity fields.
