NOTES

JXD

Markus presented this document that contains several example JXD patterns:

https://www.oasis-open.org/committees/download.php/58924/jxd%20v2.pdf

This document contains patterns for XDI literals, relations, contexts, and inner roots. We noted that often there are multiple possible JXD serializations for the same XDI graph (e.g. the choice whether to put a @type definition in the mapping block, or in the body). JSON-LD also often gives developers choice to serialize a graph in several different ways.

Phil said he liked the JXD format, because unlike previous formats it has the ability to cleanly separate type semantics from the values.

Markus pointed out that the pattern for inner roots in JXD (setting “@type” to “@graph”) effectively demonstrates one key difference between the XDI and RDF graph models, since in RDF it is not possible to have a nested graph as the object of a triple.
