AGENDA

Note: due to travel, Drummond will not be able to attend the majority of the meeting (he will attempt to dial-in during a layover on a cross-country plane flight).XDI Core: Spec Drafting Update
Drummond has uploaded the latest draft:

https://www.oasis-open.org/committees/document.php?document_id=56520&wg_abbrev=xdi

The new section is the Namespace Architecture section of XDI Addressing.

The main sections remaining for Drummond to draft are:

Internationalization

Canonicalization

IRIs

XDI Schemes

Versioning

Proposed XDI Identifier Canonicalization Rules
In preparing to write the Identifier Canonicalization section of XDI Namespaces, Drummond proposes that the TC adopt the following rules for “extreme canonicalization” XDI identifiers because this will ensure the fewest false positives and false negatives in identifier matching:

Only allow digits, lowercase letters, and three symbol characters (dot, dash, and underscore) in native XDI identifiers in the ASCII range. Uppercase characters MUST be escape encoded (thereby preserving uppercase letter matching for systems that need it).

Characters above the ASCII range MUST apply the most stringent form of Unicode normalization (as specified by Joseph).

IRIs used within XDI addresses (in parentheses) MUST be normalized according to their scheme.

Variables for Literal Nodes
So far, we have been using XDI variables to act as placeholders for (one or more) XDI context nodes. Markus has come across a use case where we may want to also use XDI variables for literal nodes (e.g. in link contract instantiation). The challenge here is that XDI variables are themselves context nodes, not literal nodes. Markus will explain further and ask for feedback on a proposed solution.
Messaging Walkthrough and XDI Channels
Markus has finished his “change of address walkthrough” and is now working on completing the original “messaging walkthrough”. See:
