Feedback on Atom Activity Base Schema
Beau Lebens
It's quite possible that I'm repeating previous comments or am
off-mark in some other way, but I was tinkering about today and read
through http://martin.atkins.me.uk/specs/activitystreams/activityschema
and wanted to post up some comments/suggestions/fixes for the
document, in case anyone finds them useful:
- there are some missing references to what element should be used
(and the specific details of that element) for certain pieces of data,
e.g. Article > summary
- Many mime types reference text/html, I don't know if it's necessary
to specifically allow XHTML documents via application/xhtml+xml ?
- 3.2.5. Image, near the start says "A photo has the following
properties: " and references "photo" in a few other places which
causes confusion since the next section is specifically for Photo
objects
- "time and date the photo was taken" is listed under Image, but then
is explicitly listed as difference for Photo
- the "player applet" property of Video and Audio objects seems a bit
ambiguous, is there a real-world example of this?
- if there are any optional properties for objects they should be
indicated (seems like quite a few could potentially be optional)
- is there a suggested method for creating unique identifiers for
objects? For Person it'd be neat if it was something like md5(email)
(if known)*
- 5.1.1. Song says 'The "tv episode" Object type represents a song or
a recording of a song. ' -- tv episode?
- The "title" property of Song also says "The title of the movie."
I'm pretty excited about where all of this is going, even if I'm
normally just lurking, keep it up all!
Cheers,
Beau
* Disclosure: I work for Automattic, owners of Gravatar, so an md5 of
emails would allow us to use that to infer a Gravatar URL, but I still
think it's a handy unique identifier ;)

paragraph. But doesn't have to be. Used to interest the reader to
click the link to the full article. We can add it to the spec

yet so we should remove it from our implementors draft 1. All of the
elements which extend atom are optional. As far as creating
identifiers we used tags which concatenated our company web site and
our internal ids and object type but the big point is that these are
really not unique. For people encrypted email addresses or links to
their profile page would be great so you can correlate across networks

How can following user activities be expressed:
- stop sharing a file for a user group
- deleting a file
- removing a tag on a file
Should for this be used a verb like:
http://activitystrea.ms/schema/1.0/delete
or are there other ways for doing this?

Max

I believe with Activity Streams there is great potential to create
new social mash services (e.g social value evaluation, search engine
integration, aggregation of users contributions/credentials across
multiple platform etc.) versus just a simple aggregated activity
feed of a person.
