Metadata as placeholder for portrayal rules.Character set (should be the same for the whole family of standards)Diagram technique. UML is not suitable for all kind of figures, and the diagram techniques might be harmonized.Functional languages. There is a need for standardizing a functional language (or to more precise an action language) for several standards, and avoid a mixed set of Gopher, SQL, ++,. OCL is not the correct choice for actions, but an extension of UML is under construction (UML-action language).Terminology. All comments on terms not specific to Portrayal will be handled to the terminology team.

WI5 Conformance and testing.The work on conformance clause in WI16 aligns well with the principles in WI5, but needs further improvement.

WI11 Spatial referencing by coordinates.Discussions on terminology and concepts like stability. The concepts on coordinate reference system in WI11 is changed, and WI16 must be restructured according to this. REM Later discussions with PT11 has clarified that this was resolved during the Victoria meeting.

WI13 Quality principles. Should WI13 be the placeholder of a quality element on positional stability, or as an annex in WI16.

WI16 PositioningWI16 PositioningUnresolved issues

UMLThe UML description is started, but needs to be completed.

Conformance clauseThe conformance clause needs to be verified in accordance with WI5

TerminologyThere were several comments on positioning services terms discussed in Beijing, half of them are still unresolved.

Coordinate reference system The draft needs to be restructured according to the new structure in WI11REM Later discussions with PT11 has clarified that there has been no restructuring since Victoria.

WI16 PositioningWI16 PositioningDate for CD submission….

One more meeting is needed to handle the unresolved issues. (Estimated to October)

UML modelling assistance is required.

The Services WD (WI19) will have a normative part on “How to write abstract service specifications and conforming implementation specifications (one-way and two-way)”. A proposal for this is estimated to be finalised by 98-11. To ensure that Positioning services is written according to this guidelines, a delay is required.

Proposal 1998-12.

Character set This standard adopts the following

international character set standards: ISO/IEC 8859-1 ISO/IEC 10646-1, UCS-2, UTF-8, UTF-16 ISO/IEC 10646-2, UCS-4

These standards define an international recognised repertoire of characters and their encoding.
