This page is part of the work of the Needs and Preferences Working Group.

The tables below collect various properties describing a context of use, including aspects such as environment, situation, time, location. These are collected from other projects, standards and technologies.

As discussed in the meeting on 2012-06-26, please feel free to add relevant properties into the table.

  • Vassilis: User Profile Ontology, paper on context modeling, SOUPA ontologies:
    • Outcome:
      • The review of the SOUPA ontologies, resulted in a few context properties that may be considered for reuse. The general practice for defining these parameters are via OWL enumerated classes, i.e.  Direction = {N S E W NW NE SW SE}, DistanceUnit = {Mile Yard Foot Inch Kilometer Meter Centimeter}.
      • The same practice (i.e. definition of OWL enumerated classes) is currently followed in the User Profile Ontology, e.g. the Location class includes the subclasses "IndoorLocation" and "OutdoorLocation", each of which has been defined as enumerated class ({Classroom Home HomeOffice WorkOffice LivingRoom Restaurant ...} and {Car Mall Park ...}, respectively)."

Environment

Property name (URI) Value space Default value English description Reference to standard, project Is core?
urn:ietf:params:xml:ns:pidf:rpid:place-is For audio: noisy, ok, quiet, unknown;
for video: toobright, ok, dark, unknown;
for text (e.g. RTT): uncomfortable, inappropriate, ok, unknown.
- ("unknown" could be a suitable default) "describes properties of the place the person is currently at" RFC 4480: Place-is Element
(empty row)

Situation

Property name (URI) Value space Default value English description Reference to standard, project Is core?
urn:ietf:params:xml:ns:pidf:rpid:situation A value form the enumeration in RFC 4480, or IANA-registered values from other namespaces - "what the person is currently doing, expressed as an enumeration of activity-describing elements. A person can be engaged in multiple activities at the same time, e.g., traveling and having a meal." IETF RFC 4480: Activities Element
urn:ietf:params:xml:ns:pidf:rpid:privacy enumeration (audio, text, unknown, video) - ("unknown" could be a suitable default) "which types of communication third parties in the vicinity of the presentity are unlikely to be able to intercept accidentally or intentionally" (emphasis added) IETF RFC 4480: Privacy Element
(empty row)

Time

Property name (URI) Value space Default value English description Reference to standard, project Is core?
urn:ietf:params:xml:ns:pidf:rpid:time-offset a positive or negative integer - "number of minutes of offset from UTC at the person's current location" RFC 4480: Time Offset
(empty row)

Location

Property name (URI) Value space Default value English description Reference to standard, project Is core?
urn:ietf:params:xml:ns:pidf:rpid:place-type Types enumerated in RFC 4589 or additional IANA-registered values as described in RFC 4589. - "the type of place the person is currently at" RFC 4480: Place-type Element and RFC 4589
(empty row)

Other

Property name (URI) Value space Default value English description Reference to standard, project Is core?
urn:ietf:params:xml:ns:pidf:rpid:mood At least the enumeration in XEP-0107 - "the mood of the presentity" RFC 4480: Mood Element
urn:ietf:params:xml:ns:pidf:rpid:user-input active or idle - "records the user-input or usage state of the service or device, based on human user input, e.g., keyboard, pointing device, or voice. (...) The mechanism for such aggregation is beyond the scope of this document, but generally reflects the most recent user input across all devices and services" RFC 4480: User-Input Element
