wot-td issue 16 - Handle huge set of Thing Descriptions (pagination, streaming, etc.)

https://github.com/w3c/wot-discovery/issues/16

Pagination / streaming

<kaz> wot-discovery issue 98 - Need information model for directory

Review information model

Changes by Farshid: Information model -> Directory service API

model

Introduce section header "Information model" in $6

Including Figure 4

Directory should expose a TD (missing in diagram)

Directory is a "special" thing

TDD exposes -> described by a TD

Self-described thing exposes TD

McCool has a PR for additional responses (e.g. error codes)

Farshid provided several examples

e.g. Example 4

<kaz> EXAMPLE 4: Example TD with Registration Info

"Enriched" already agreed

vs. original TD

<kaz> Figure 4 The conceptual class diagram of the exploration mechanisms

McCool tdd:registration in diagram a bit confusing

Self described thing cannot return registration information

Two boxes? Original + enriched TD

Need several view on the information model

Where to store pagination information?

Has impact on RDF generation

New issue: https://github.com/w3c/wot-discovery/issues/116

https://github.com/w3c/wot-discovery/issues/98 "need" -> "refine"

Internal information model vs. views on information model
