The ISO committee (SC34) has sent out a proposal for a new ISO work item, called SDShare. SC34 is now doing a 3-month ballot to see if member countries wish to develop this into a full ISO standard.
The proposal defines SDShare as follows:
The proposal specifies an underlying syndication protocol for the exchange of information about semantic descriptions. The protocol conforms to the Atom Syndication Format and the Topic Maps Data Model (TMDM) and works with semantic descriptions represented as in XTM 1.0, XTM 2.0 and RDF/XML. It defines layers of syndication feeds that a conforming application must provide. Finally it defines algorithms for the provisions and processing of the different feeds on servers and clients.
For those who don’t recognize it, this is the SDShare protocol already developed by NetworkedPlanet and others, for transmitting streams of changes to a topic map using an Atom feed.
