19108 Temporal schema

• 19109 states that 19108 shall be used for temporal attributes

• 19103 defines basic datatypes - e.g. Date, DateAndTime

Change in 19109 to allow use of basic datatypes from 19103

19108 Temporal schema• The UML-model in 19108 requires an explicit

association between TM_Position and TM_ReferenceSystem

• In the text it is written that TM_Position & TM_Refsys only needed when other than Gregorian calendar and UTC

Improve writing in 19108 about TM_Position & TM_ReferenceSystem

Specify what is allowed in a profile

19109 Rules for appl. schema

• The role of GFM unclear • Model in UML and not following the ”main rules”

in 19109 - A RISK!

Some conclusions Joint Nordic implementation project - phase 1

• Useful

• Complex

• Harmonize ISO 19100

• Need more specific models
