5. 1998.03.025 ISO/TC 211 WG4 Unresolved comments for editing management committee. oMetadata as placeholder for portrayal rules. oCharacter set (should be the same for the whole family of standards) oDiagram technique. UML is not suitable for all kind of figures, and the diagram techniques might be harmonized. oFunctional 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). oTerminology. All comments on terms not specific to Portrayal will be handled to the terminology team.

10. 1998.03.0210 Harmonizing ISO/TC 211 and OpenGIS Service Architecture and identified services The Geospatial Domain Services describes the various services identified in the OpenGIS service architecture These services have been mapped into the ISO/TC211 service categories.

11. 1998.03.0211 WI19 Services oIdentification of services: Completed (30 services) oNormative: How to write abstract service specifications and conforming implementation specifications (one-way and two-way) - by 98-11 oApply service specification approach to Positioning service (from part X) and Feature access, query and update (from OGC + SQL-3/MM) - by 99-03 oPropose new work items: Catalogue Service, Coordinate Transformation Service, Imagery/Gridded Data/Coverage access, query and update oCD by 1999-03 (to incorporate work on Feature access, query and update)

13. 1998.03.0213 WI16 Positioning Joint sessions during the Beijing - meeting 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.

14. 1998.03.0214 WI16 Positioning Unresolved issues UML The UML description is started, but needs to be completed. Conformance clause The conformance clause needs to be verified in accordance with WI5 Terminology There 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 WI11 REM Later discussions with PT11 has clarified that there has been no restructuring since Victoria.

15. 1998.03.0215 WI16 Positioning Date for CD submission…. oOne more meeting is needed to handle the unresolved issues. (Estimated to October) oUML modelling assistance is required. oThe 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. oProposal 1998-12.
