Distributed Conversation Formats

Examples of Related Formats

Email/Usenet

Email and Usenet both keep track of discussion threads in a non-central manner using headers and references to message IDs. Some common headers and their use are highlighted in RFC2076 - Common Internet Message Headers section 3.6:

Thread Description Language

Thread Description Language - TDL is an RDF vocabulary for describing threaded discussions, such as Usenet, weblogs, bulletin boards, and e-mail conversations.

TDL v3 defines the following properties:

Discussion of TDL

  1. respondsNegativelyTo, respondsPositivelyTo are beyond the scope of this spec. They can both be implemented using vote-links.
  2. Without those, respondsTo remains the main connector between posts in a thread.
  3. mentions and discusses seem to be splitting hairs. It appears that both of them can be replaced by using the CITE tag.
  4. follows seems to be designed for use in a central registry that tracks threads and therefore is useless for a distributed solution.

IBIS - Issues Based Information Systems

Kunz's Issue Based Information Systems (IBIS) provide a framework for collaborative understanding of the major issues and implications surrounding what are described as ``wicked problems (problems that lack a definitive formulation). Understanding is achieved by using hypertext components to create structured arguments surrounding the issues. (Weblog Kitchen)

 The hypertext model of IBIS consists of three node types:
  1. issues
  2. positions
  3. arguments
 
 Eight link types represent the allowable relationships between these nodes:
  1. generalizes
  2. specializes
  3. replaces
  4. questions
  5. is_suggested_by
  6. responds_to
  7. objects_to
  8. supports

Discussion of IBIS

Similar to TDL, IBIS seems to tackle a bigger problem than the one discussed here.

SIOC - Semantically-Interlinked Online Communities

SIOC (Semantically Interlinked Online Communities) is an ontology for describing discussion forums and posts on topic threads in online community sites. This includes but is not limited to: blogs, bulletin boards, mailing lists, newsgroups, etc.

Relevant properties defined under SIOC:

Examples of Use

From Email we get two basic relations between message:

From various publications (often of standards) we get:

Citation of resources comes in several flavors:

Atom Threading Extensions

An extension has been created in RFC-4685 for Threading, essentially the ability, with Atom, to have cross-site, continuous conversations.
