7. Clause 1
Contribution GPLR registries to geographic information interoperability
maintains backward compatibility with ISO6709:1983
allows adoption of new XML -based encoding mechanisms
constitutes an appropriate solution to enable interoperability at the syntactic level considering the existence of various formats
supports encoding and decoding processes by providing a standard mechanism for describing encoding format of geographic point locations with a unique reference

8. Clause 2 Review of encoding mechanisms
Standard representation of geographic point location by coordinates (ISO6709)
Geography markup language point profile
DCMI Point encoding scheme
Geo- Virtual Reality Modeling Language and X3D
Natural Area Coding System
Compact text encoding
Keyhole Markup Language
ISO 8211
LandXML
EROS Global Land 1-KM AVHRR Project
XDK Danish exchange format for GIS data
UTM (Universal Transverse Mercator)
MGRS (Military Grid Reference System)

10. PT 19146 Cross-Domain Vocabularies
Project Leader: Andew Jones
Target: IS
Objective: to cross-map between TC211 terminology and technical vocabularies that have been adopted by industry-oriented geo-spatial communities for routine usage
Establish a consistent approach to cross-mapping
Implement cross-mapping between TC 211 and TC 204
Underpinning standards:
ISO :2000 Terminology Work – Vocabulary – Part 1: Theory and application
ISO 19135:2005 Geographic Information – Procedures for item registration

11. Approach
Strong emphasis on ensuring collaboration between vocabulary owners
Document structure
Principles for cross-mapping of vocabularies
Approach
Governance
Reference vocabulary
Cross-mapping process
Documentation and publication
Register schema
Cross-mapping between ISO/TC 211 and ISO/TC 204

12. Principles Terminology is to be rationalised rather than proliferated
Vocabulary cross-mapping will provide a thesaurus, not a taxonomy or ontology
A stable reference vocabulary, maintained by a recognised standards body, will be adopted for all cross-mapping undertakings involving a particular discipline
Cross-mapping must proceed as a collaborative venture
Cross-mapping must not circumvent established processes
Cross-mapping must be recognised through publication in a register
Cross-mapping must accommodate continuous change

13. Activity to Date Next Steps Balloted as a NWIP prior to 23rd Plenary
Project team – 16 people from 11 countries
Australia confirmed as project leader
WD1 was provided with the NWIP
WD2 (much expanded) was distributed during
1st Project team meeting in Rome on /29
WD2 reviewed in its entirety
General support by the PT for WD2
Discussion primarily focussed on the approach to classifying cross-mapped relationships
Next Steps
Proceed to WD3
Final WD before CD
Scheduled to be issued as CD in
Appears to be achievable

14. Summary of discussions on registers in WG9 meeting
Ad Hoc Group on Registers as reported to the Riyadh Plenary (and in document N2110).
Task of the Ad Hoc Group
Identify which registers are required within ISO/TC 211;
Make a priority list;
Propose how the identified registered can be established;
Propose how to maintain the registers.

15. Summary of Ad Hoc meeting in Riyadh Last Year
ISO/TC211 should develop very simple, stable, high level registers.
ISO register of geodetic codes and parameters should be established with the top priority. It may be a hierarchical register such that ISO register consists of its principal register.
Establishing a register of terminology should be considered in more detail, in connection with cross-domain vocabularies (N 2051) and multi-lingual glossary of items (N 2075).
While ISO/TC211 should have a set of registers in a sense as in 1, there has been discussions on registers:
　　　　　19126, 19138, 19145, 19115,
The maintenance of a register requires establishing consensus in a group. For ISO TC211 that group would be ISO TC211 itself, and then the registration maintenance be approved by resolution of the whole TC at plenary.
Depending upon the degree to which the register content duplicates the ISO/TC211 series of standards, an ISO copyright issue may be raised, and ISO/TC211 should contact ISO CS for permission of making the register public. This would be necessary for the terminology register.

16. WG9 discussions on registers (a follow-up of Report of Ad Hoc Group on Registers)
WG9 noted and supported the findings of the Ad Hoc Group on Registers as reported to the Riyadh Plenary (and in document N2110). It further noted that there has been no resolution of the report items concerning:
The Secretariat taking on the role of registration authority for high level ISO/TC 211 registers; and
The ISO copyright issues.
And that this is already standing in the way of use of ISO/TS and ISO/TS
WG9 also noted the work of PT and the indications that a NWIP will come forward, which will require a register of representations of geographic point locations. WG9 was concerned to ensure that such registration issues were considered at NWIP stage, not left to later stages in the standardisation process.
