TFDI Status on 30 Sep2015 Prepared by Soumya

TF-DI Status on 30 -Sep-2015 Prepared by Soumya Kanti Datta TF-DI Coordinator in W 3 C Wo. T IG Research Engineer, Eurecom, France

Status (1/2) • Discussions • • Definition, purpose and use cases Scopes and dimensions Simplifying discovery Presentations on discovery technologies • Requirements study from use cases (not an immediate priority) • Compiling technology landscape • Six categories • Evaluation of these categories undergoing • Discussion of security and privacy aspects of discovery • Security requirements study • Authorization

Status (2/2) • Provisioning • Started the discussion • Presentation on OMA Lw. M 2 M as a candidate technology • Proposal for a discovery work item in Wo. T WG • Joint sessions with TF-AP and TF-TD • E. g. , how discovery can benefit from thing description (TD)

Compilation of Tech Landscape (1/2) • Wiki https: //www. w 3. org/Wo. T/IG/wiki/Discovery_Categories_and_Tech_ Landscape • Six Categories with examples and brief descriptions • • • Finding things around me (NFC, Uri. Beacon) Finding things on my network (m. DNS, Multicast Co. AP) Searching in directories (Co. RE Resource Directory, XMPP Io. T Discovery) Searching via peers (P 2 P based approaches) Accessing thing metadata (Co. RE Link Format, HATEOAS) Semantic based discovery (Mostly research articles)

Compilation of Tech Landscape (2/2) • Evaluation Criteria • Interaction Pattern – does it share the current draft of interaction pattern in that discovery category • Support of higher layer discover concept – does it provide means for higher layer discovery using thing descriptions • Bootstrapping – what means are provided to start/interact with things after discovery • Lifetime / sleepy nodes – does it provide means specifically supporting sleeping times of constrained devices • S&P – what S&P requirements are identified and addressed • Range – important for “finding things around me” • Support for (physically) local/remote discovery of things • Richness of query – how much context can be passed to the discovery API (as input) • Ranking of results – how does the discovery API is ranking the results of discovery

Preparation of the discussion @TPAC • Main objectives • • TF-DI report on activities and post TPAC plans Present, discuss and verify TF-DI tech landscape and their evaluation Continue security & privacy discussions Provisioning discussion • Replicate the efforts on discovery to provisioning • E. g. , work towards a tech landscape study • Discuss, update – Wo. T WG work item on discovery
