Subject: Re: XDI Symbol Table (was: Re: [xdi] Re: Friday's XDI TC call)

Does this mean I am not allowed to have @neustar*leschasen or =chasen*les?

I finally had a chance to review the new https://wiki.oasis-open.org/xdi/XdiSymbolTable page.

Dan, note that I updated some of the descriptions to match what we are putting in the XDI Core spec.

Les, to answer your question, all context symbols can be used for what in hierarchical namespaces is called "delegation" (although delegation works differently in XDI - that's a good subject for the next TC telecon). Regarding the * context symbol, in XRI syntax it was the "delegation character" for reassignable identifiers. In XDI, this has changed. * is now the context symbol for a "thing", meaning an entity that is not a natural person or a legal entity (group, organization, trademark, etc.)

Note that I also clarified the wording in the table about "ownership", as this applies to the semantics of the = and @ context symbols as well.
  • = is the context for an identifier for a natural person. It is not just an identifier "owned" by a person, but one that identifies a person (this, too, is a departure from XRI semantics).
  • = is the context for an identifier for a non-personal legal entity. It is not just an identifier "owned" by a legal entity, but one that identifies a legal entity of some kind (group, organizaton, trademark, etc.)
It follows from these definitions that * is the context for an identifier that identifies anything else that is not a natural person or a legal entity.

This table is a great idea.   One quetion.

This says that * is an identifier for a thing.  Is it really?  I thought this was a delegation character.

Suggestion: let's turn this into a page on the XDI TC wiki. Dan, would you be willing to do that?

To make it easy, I've already started the page for you:

Just login to the wiki and click the Edit button.

Note that MoinMoin table syntax can be a little funky. The easiest way to learn it is to study an existing table in "raw" mode (which you can see by clicking the "Do" button next to the "Raw Text" drop-down option at the top of any XDI TC wiki page). Here's a good one to look at:

Dan and others,

Here's the updated symbol table after we worked on it during today's call.
I'm also sending you the examples we created.

Dan would you like to review this to see if it makes sense?
When we're satisfied with this we can upload it to the XDI TC's document repository.

I'd like to take a few minutes to get some help filling out the attached XDI symbol table so that I and potentially others can use it as a quick reference when reading XDI syntax.

I don't think it makes a lot of sense to talk much about the root/merge topic without you..

But yes let's try to use the time for other things, e.g. the ABNF (which I haven't been following very much), or the $ref/$set problems.
I'll send out an agenda in a few min.

I am in London this week, flying back tomorrow, and I expected to be able to make today's the XDI TC telecon but just had an important meeting scheduled that will conflict.

So I will leave it to Markus to decide if we should still have a call and, if so, to send out an agenda.
