Tags for ActivityStrea.ms
I’ve been looking at the promising new ActivityStrea.ms proposed standard, based on the existing Atom standard. ActivityStrea.ms promises to enable sharing activity streams across applications. This is a key piece of the “distributed social network” vision, where people can distribute and aggregate their activities across multiple sites and tools.
I was thinking through a distributed community potential use case – and saw what seems to be an item that is missing but easy to add. The current ActivityStrea.ms proposal seems logically based on an assumption that a user would want to distribute or aggregate all of their updates. Or, perhaps choose to share updates based on *type* of content or action – I want to share my blog post updates, but not my photos.
What’s missing is the concept of syndicating or aggregating by *topic*. Let’s say I have a stream of messages talking about web standards, politics, and music. I want to syndicate only music-related updates to a music site. What’s needed seems simple – a way of adding a piece of metadata – a tag – that identifies a given update as a music-related update. Then, I can choose to share only those updates to the music site.
Fortunately, there are ways to represent Tags in Atom – see this representation in WordPress.. So it would be possible to address this need fairly simply, by adding the use of Tag as a recommended best practice for ActivityStrea.ms implementors. No need for a new standard, just leverage the existing one for this new use case.
As the uses of Activity Streams proliferate, and the social contexts in which they are used become more complex, people are going to want to choose discretion about what to share where — not just for reasons of privacy, but for reasons of attention management. Baking in a tag best practice could lay the groundwork for more socially useful Activity Stream sharing.
What do you think? Am I missing something obvious?
