WG9: Additional parts of 19107 for various extensions to the (basic) spatial schema

[gbuehler]

A requirement is a request for an organization to add or support something that they do not already cover or support. These might be in the form of a new feature or a new standard. It might need to spawn an New Work Item (ISO), or new Standards Working Group (OGC).

I changed this request to be a new requirement for ISO 19107 and also changed the title to reflect this. The renaming of ISO 19107 to ISO 19107-1 will be dealt with by a vote of the ISO/TC 211 plenary meeting.
The extensions intended for ISO 19107 are not part of the abstract schema. Their original source is Simple Features, which is an OGC standard that was shared with ISO TC 211 as ISO 19125. ISO 19125 has always been a multi-part standard, and the plan for the basic outline of 19125 is being discussed in both OGC and ISO TC 211. Most of not all the topics mentioned in earlier discussions have been parts of 19125 Simple Features. The name will change because only the core of the new 19125 will match the old simple features. The working title is currently "features, geometry and their representations". The series will concentrate on the application of 19111, 19107 and 19109 to data sets for information management or manipulations applications. ISO 19107 is only part of the solutions. The WKT will cover both geometry and features, and will produce text-based representations for various application environments. Variations will at least cover JSON formats, and possibly Lisp or other Key-Value pair structures.

The idea to make 19107 multipart has been dropped. ISO 19125 will extend each of 19107, 19111 and 19109. Combining parts of these implementation issues in abstract standards is inappropriate. The current part 2 of the old 19125 is an important source for a JTC1 standard called SQL/MM part 3 Spatial. Implementation issues for this will also be included in parts of 19125.

The eventual volume division of 19125 is under joint consideration in ISO TC 211 WG9, and OGC (the Simple Features Standards Working Group, SF SWG).
The basic assumption is incorrect. The WKT is not an extension to the Spatial Schema, it is a representation of types in the geometry (spatial objects).

WKT and other representation formats are part of implementation standards like 19125, not the basic abstract model.
