McCool Comments

Spec. is http centric. New issue:

PR 152

https://github.com/w3c/wot-discovery/pull/152 PR 152 - Add Registration ID to Enriched TD

Farshid: Found a way identifying anonymous TDs (6.2.1.1, 6.2.1.2)

McCool Breaks canonicalization and signing

Farshid: Must "un-enrich"

To be described

Enrichment needed for anon. TDs otherwise not

McCool Should also be discussed in WoT-Security wrt UUID

Farshid will create issue about this.

PR 153

https://github.com/w3c/wot-discovery/pull/153 PR 153 - Listing with pagination

Header based pagination

McCool JSONpath queries instead of envelope based pagination

Header based pagination -> optional

According to RFC8288

Not identical to LDP paging

McCool Merged for future proposal, only optional

PR 155

https://github.com/w3c/wot-discovery/pull/155 PR 155 - Simplifying the events API query and payload

Events API
