  21. Outline of Review Summary (1st plan) • Introduction • Background • Purpose and justification • Overview • Scope • References • Terms and definitions • Review • How organizations handle the use of many representations of GPL • Static vs. dynamic data conversion and registry (difference) • Contribution to geographic information interoperability • Review of encoding mechanisms (popularity, basis) • Preliminary content and structure of the registry • Relationships of the registry with other ISO documents (e.g. 6709) • Business case for registration authority • Conclusion and recommendations • Annexes? WI 19145

  22. WI 19145 Timetable • Contributions (mid August 2006) • First draft (mid October 2006)⇒PTmembers • PT meeting in Riyadh to discuss the draft • Final draft mid December 2006 • Review by WG9 by the end of January 2007 • Draft Review Summary mid February 2007

  23. Preliminary content andstructure of the registry (To be refined) • Unique identifier • Name • Version (version number, dates, amendment number …) • Status of the geographic representation format • Data elements and their types • Structure of the data (order of items, type of separator, tags, etc.) • Description of the format (another possible way is to include the description as part of the registry) • Physical data model? • Type of physical data model (e.g. XML Schema?) Profile (e.g. GML point profile)? • Binary vs. text? • Textual description (Characterstring or a Reference to a specification (e.g. CI_Citation)) • Compressed or not • “Parameters for conversion” • Compression mechanism, • Name • Version • Algorithm? • Proprietary format or not (patented or not?)
