A file-extension for ActivityPub /ActivityStream files.
...
On many web-servers, the Content-Type returned when serving a file is based on the file-extension of the file.
Ex: .txt for text files, .gz for gzip files, .gmni for gemtext files, etc.
I am not aware of a widely used file-extension for ActivityStreams / ActivityPub files.
...
#ActivityPub #ActivityStreams #DeSo #FediDev #FediDevs #Fediverse #FileExtension #OpenSocial #SocialWeb

.json isn't sufficient, since it would produce a Content-Type of "application/json" rather than "application/activity+json".
ActivityPub / ActivityStream files need their own file-extension.
...
#ActivityPub #ActivityStreams #DeSo #FediDev #FediDevs #Fediverse #FileExtension #OpenSocial #SocialWeb

A good file-extension for ActivityPub / ActivityStream files might be:
.activity
And maybe also:
.jsonactivity
Those could be used to trigger a web-server to respond with the Content-Type "application/activity+json".
.
#ActivityPub #ActivityStreams #DeSo #FediDev #FediDevs #Fediverse #FileExtension #OpenSocial #SocialWeb
@reiver why not .activity.jsonld ?
I think that mime.types file in *nixes already uses this convention for other mime-types (application/tm+json, application/sarif+json, etc.)
That would work for systems that understand the extension of a file "filename.activity.jsonld" to ".activity.jsonld" rather than ".jsonld".
I know some systems would only understand the file-extension to be only ".jsonld".
(Which works well with files such as "movie.mp4.gz" and others like it.)
What about, something without more than one dot (".")?
What about .activity-jsonld or .jsonld-activity, etc?
@reiver I don't know what you mean by "systems" ... a .jsonld extension is supported already by *nix machines through its /etc/mime.type file and the tooling built around that. That translates it to a application/ld+json mime-type. It hasn't made it to IANA yet as far as I see, but we can only hope.
It's not clear to me why it would be important to you to know that a JSONLD file is of the specific ActivityPub flavour.
