NOTES

JXD

Markus explained that there have been no changes to the JXD format since the last call, but that there is now experimental code for reading/writing JXD and converting it both to and from other XDI formats.

This can be done using the XDI Validator and XDI Converter tools of the XDI2 project:

https://server.xdi2.org/XDIValidator

https://server.xdi2.org/XDIConverter

We discussed again the fact that an XDI graph can be serialized to JXD in different ways. Markus’ opinion is that this kind of flexibility is a good thing and noted that similar choice exists in JSON-LD, however there are also advantages in having only “one way of doing things”.

Phil thought that the different variations in JXD can be understood using relatively simple syntactic rules and transformations, without requiring deep understanding of XDI semantics.

Les suggested that with progress on JXD, previous XDI formats may not be necessary anymore and could perhaps be deprecated. Markus agreed JXD seems preferable to all previous formats. One advantage of the XDI DISPLAY format is that it closely mirrors the underlying XDI graph structure. In this format, statements/arcs in the XDI graph are simply listed individually similar to RDF’s N-Triples format.

Markus said his interest is now to finalize the JXD format and then apply it to concrete use cases, such as ongoing work on Decentralized Identifiers (DIDs) as well as claims on distributed ledgers.
