Activity Stream Documentation Language (ASDL)

The Activity Stream Documentation Language (ASDL) is a language to make Activity Streams (AS) more self-describing. It is work in progress, with the current version being targeted at AS 1.0 rather than the in-flux work on AS 2.0 at the W3C Social Web WG.

AS are great at sharing information about activities across applications and services. As long as AS use the built-in vocabulary, consensus is established through the way how this vocabulary is defined. AS 1.0 and AS 2.0 have definitions for their core vocabularies. (The current version of AS 2.0 confusingly calls the actual core vocabulary the "extended vocabulary", but hopefully this terminology will be cleaned up in future versions.)

The goal of ASDL is to allow AS publishers to provide access to their AS vocabularies. It is not intended as a complete description language for those vocabularies. It simply serves as an inventory of concepts that consumers of AS should be prepared to process, and allows publishers of those AS vocabularies to make documentation snippets available, and link to more detailed documentation or formal descriptions (whatever their preference is).

ASDL is work in progress; currently the following resources are available:
