RE: Time Ontology outstanding issues: Notes to be removed or incorporated

Dear Time Ontologists,

Many of the following Notes have already been incorporated into the body of the Editor’s Draft text of the Time Ontology, so I propose to remove them next week, unless anyone can think of a reason to keep them.

-------------
2. Changes from previous versions
Note The SDWWG requirement 5.49 Temporal vagueness relates to this.
Propose to incorporate into text of Issue 3.

4.3 Time position and time units
Note DateTimeDescription covers the case that was defined in the original note, and retains the original class name.
Propose to delete as the Ontology is intended to replace the previous version

Note These classes address the 'date' and 'time' requirement from 5.7 Date, time and duration
Propose to delete as the Ontology is intended to be used separately from the Requirements document

4.4 Duration
Note DurationDescription covers the case that was in the original note, and retains the original class name.
Propose to delete as the Ontology is intended to replace the previous version

Note These classes address the 'duration' requirement from 5.7 Date, time and duration
Propose to delete as the Ontology is intended to be used separately from the Requirements document

5. Vocabulary specification
Note The SDWWG requirement 5.25 Multilingual support relates to the documentation of the ontology.
Propose to delete as covered by W3C documentation policy

5.6 Class: TRS [Temporal Reference System]
Note A taxonomy of temporal reference systems is provided in ISO 19108:2002 [ISO-19108], including (a) calendar + clock systems; (b) temporal coordinate systems; (c) temporal ordinal reference systems.
Propose to leave as a useful Note unless there is a W3C policy against this, or incorporate into main body of text

Note This TRS support addresses the following requirements from the SDWWG: 5.9 Different time models, 5.48 Temporal reference system, 5.28 Nominal temporal references.
Propose to delete as the Ontology is intended to be used separately from the Requirements document

5.9 Class: DayOfWeek
Note In this version of the ontology, membership of the class DayofWeek is open, to allow for alternative week lengths and different day names.
Propose to incorporate into main body of text

5.11 Class: TemporalUnit
Note In this version of the ontology, membership of the class TemporalUnit is open, to allow for additional temporal units used in some technical applications (e.g. millions of years, Baha'i month).
Propose to incorporate into main body of text

5.16 Datatype: generalYear
Note While this pattern achieves the correct lexical form, the value-space is not defined, so a generic OWL2 processor cannot compute ordering relationships of values of this type.
Propose to delete. Already incorporated into main body of text

5.17 Datatype: generalMonth
Note While this pattern achieves the correct lexical form, the value-space is not defined, so a generic OWL2 processor cannot compute ordering relationships of values of this type.
Propose to delete. Already incorporated into main body of text

5.18 Datatype: generalDay
Note While this pattern achieves the correct lexical form, the value-space is not defined, so a generic OWL2 processor cannot compute ordering relationships of values of this type.
Propose to delete. Already incorporated into main body of text

6. Examples
6.1 iCalendar
Note This example replaces the one from [OWL-T].
Propose to delete as the Ontology is intended to replace the previous version

6.3 DateTimeDescription vs. dateTime
Note This example carried over from [OWL-T].
Propose to delete as the Ontology is intended to replace the previous version

6.6 A Use Case for Scheduling
Note This example carried over from [OWL-T].
Propose to delete as the Ontology is intended to replace the previous version

6.7 Web commerce applications
Note This example carried over from [OWL-T].
Propose to delete as the Ontology is intended to replace the previous version

B. Time Zone Vocabulary
Note This section unaltered from [OWL-T].
Propose to delete as the Ontology is intended to replace the previous version
