SSN-XG Liaison activities

Jump to: navigation, search

See the different communities of practice identified in Communities

Liaisons - work by other organisations:

  • Work by OGC on SWE standards
  • Coordination role taken by ISO/IEC JTC 1 Study Group on Sensor Networks (SGSN)
    • can help to define what the SSN-XG does in the broader landscape of SN standards
  • Other standard organisations working for some specific communities

W3C and OGC viewed as working at the apps level


IEEE1451 has influenced the SWE standards (SensorML and TransducerML)

  • precise the relationship / dependency

ETSI M2M (Telecom actors) has published early drafts

ITU work on Ubiquitous Sensor Networks mostly focused on the "air" (wireless) interface but some tentatives to progress on specific appps (e.g. Climate Change)

Work on the ontology is horizontal - "traditional" boundaries between standard organisations are changed (see Widdowson Widdowson 2008 the NORTEL presentation at the June 2008 M2M workshop). Slide 11 defining 5 main types of interfaces which can potentially be standardised)

  • Sensor - Sensor Control
  • Sensor - Network
  • Sensor - Application
  • Sensor Control - Application
  • Network - Application

(assumption: diffferent service providers for the operation of the sensor(or devices), of the network and of the end applications)

OASIS QUOMOS TC is important because it is at the entry point for the work on ontologies for organisation (end users) which have not worked on ontologies before.

Involvement of OGC and related activities

OGC is one of the Initiating Members of the SSN-XG but does not have any nominated representative to the working group (to date).

Involvement of the SSN-XG participants in SWE

Several participants to the SSN-XG are also involved in OGC-led activities.

Luis Bermudez and Simon Cox are followers of the ongoing upgrade of SensorML

Simon Cox is co-chair of the GC GeoSemantics working group (but not directly involved in the activities listed below).

Simon Cox has continued to work on the Observations and Measurements specs (transition into an ISO TC 211 standard: ISO 19156 EC Observations and Measurements DRAFT - access limited to OGC members

Other Work on GeoSemantics at OGC

OGC GeoSemantics working group http://www.opengeospatial.org/projects/groups/semantics (irregular activity - chairs: Joshua Lieberman and Simon Cox)

Joshua chaired the W3C Geospatial Incubator Group (1 year long - closed in Nov 2007)


Work on GeoSPARQL submitted as "A proposal for an OGC Draft Candidate Standard" (~ Member submission in W3C)

Work on Sapience presented at OGC TC in December 2009

(email from Jean Gelissen (email: jean.gelissen at philips.com) 8 Mar 2009

The MPEG-V standard addresses the following areas:

  • Standardization Area A: Control Information
    • This area covers the information representation of the control information to and from devices in the physical world. Examples of these representations are the representation of sensory input devices like smart vision systems, environmental and body sensors and the like and sensory output rendering devices like lights, heaters, fans, displays, speakers and the like.
  • Standardization Area B: Sensory Information
    • This area covers the (bidirectional) information representation of information exchanged between the physical world and the virtual world as well as the information exchange between virtual worlds. Examples of these representations are the representation of haptic, emotion and avatar information.. Please note that this section will be extended with more details on the standardization areas when available.

More background information is available in the following MPEG output documents:

  1. Information exchange with Virtual Worlds: Context, Objectives and Use Cases (N9424)
  2. Requirements for MPEG-V Version 3 (N10235)
