Any public JSON activity streams?

[Robin Zimmermann]

Hi,

Are there any JSON activity streams that are publicly available? I
would like to test consuming a stream.

Thanks!

Robin.

Robin, Google+ has real-world public activity stream feeds available.
You just need one of their API Keys. Go to
http://developers.google.com/+/api/ for details. You can also use the
Abdera2 Activity Streams implementation
(http://svn.apache.org/repos/asf/abdera/abdera2/) to test against for
interop. It contains a mechanism for converting Atom feeds into
Activity Streams that you can then run through your parser.

Jason,

Is there a page on the ActivityStreams wiki that lists these (semi*)public JSON Activity Streams and open source publishing implementations thereof?

Thanks,

Tantek

*semi because "API key required" is not really public.

Every stream on http://identi.ca/ and other StatusNet sites has a linked
Activity Streams representation, using <link> and an <a> in the sidebar.

Evan, great to see but I notice there are some inconsistencies between
the streams published there and the spec. For one, the "count" field
in the stream should be "totalItems", the "type":"note" on the objects
should be "objectType":"note", the "tags" property should be an array
of objects, not strings, and the geopoint element duplicates the
functionality of the "location" property defined in the schema spec
document. As it stands, Abdera2 is able to parse the identica feeds,
but it's not able to handle each object type properly because of the
use of "type" instead of "objectType"

Good to know! Yes, I think we've been tracking the spec for a while and
got out of sync at some point.

Should be pretty easy to get these up to date, and we'll include the
changes in the upcoming 1.1 version of the software.

So, I think we caught up, there. Let me know what you think.

There's two public JSON Activity Streams for every user on Flattr.com, a unified stream is upcoming and until then we have no auto-discovery mechanism for it. I don't think we have documented the Activity Streams format in our public documentation yet, but I blogged about it when we launched it: http://voxpelli.com/2011/10/activity-streams-flattr-api/

In addition to what everyone else mentioned, some implementations are
documented on the wiki:

http://wiki.activitystrea.ms/w/browse/#view=ViewFolder&param=Implementations

However, some of this information is pretty old and so may be inaccurate.

[James Snell]

Looking good for the most part. Double check the geo coordinates in
your location.position property, it looks like there's an extra period
(.) being inserted between the latitude and longitude.

This: position: "+38.25031.-92.50046/",

Should be: position: "+38.25031-92.50046/",

Great to see. Just confirmed that will a cpl bug fixes on my end
Abdera2 is working great with the flattr and statusnet streams. Good
stuff.

I haven't tested our conformance on Google+, but you can see our json
activitystream output here:

https://developers.google.com/+/api/latest/activities#resource

Paul, conformance is pretty google with G+, there are a couples nits
here and there tho...

1. The geocode stuff in the Activity
(https://developers.google.com/+/api/latest/activities#resource)

duplicates the functionality of the "location" property defined in the

Activity Schema spec
(http://activitystrea.ms/head/activity-schema.html#location) ...

Example.. this is what's in the G+ Activity:

"geocode": string,
"address": string,
"radius": string,
"placeId": string,
"placeName": string

This just re-invents what's in the schema spec, only not as well..
(use position instead of geocode, use displayName instead of
placeName,

"location": {
"displayName": "Place Name",
"position": "+27.5916+086.5640+8850/",
"id": "urn:whatever:the.place.id",
"address": { ... },
"radius": 10
}

2. I'm confused by the crosspostSource property. Given the definition
in the documentation, crosspostSource seems to duplicate the function
of the upstreamDuplicates property, if so, not sure why not just use
that? I'd rather not have to write code to look for another id field
when performing identity equivalence checks.

Thanks for the feedback. I'll see what we can do to get better
conformance.

Hello everyone,

 

that is great to know that, activity streams is an "extension" of ATOM (XML), also is one Syndication Format.

 

In the .NET world Microsoft  has a foundation for creating Syndication Format like Atom 1.0 and RSS 2.0, which were inherited from syndication format object.

 

Some infos: http://msdn.microsoft.com/en-us/library/system.servicemodel.syndication.syndicationfeed.aspx

 

Do someone of you know, if there is an object for activity stream format like: Atom10FeedFormatter (http://msdn.microsoft.com/en-us/library/system.servicemodel.syndication.atom10feedformatter.aspx) in .NET?

 

I really need an object like "AtomActivityStream10Formatter" for my project :)

 

if there are not, should i derivite the Atom10FeedFormatter or SyndicationFormatter.

 

Thanks alot and happy weekend,

 

Hai-Nam

I have not come across anything, working on building a json based one now.
