Christopher -

I can understand your frustration.

There was some confusion regarding this particular paper. However please 
note that I authorized Arnulf to share r3 with the OSGeo community. This 
authorization was based on the OGC members approving the release if this 
paper for public use and comment.

That said, any engineering report submitted by a member goes through the 
following formal process:

1. Author(s) must post the new document to the OGC Pending Documents 
2. There is a three week internal review period in which members can review 
and comment on the document. In many ways, this is a quality control step.
3. At this point, the members can approve the release of the engineering 
report as a Discussion Paper or as a Best Practice paper. This approval may 
be by an electronic vote (which takes another week) or at an OGC face to 
face meeting. Approval of pubic release of any engineering report is an OGC 
policy and is meant to again insure a level of quality control and 
4. Assuming the document is approved for release, Greg Buehler of OGC staff 
and I then review the document and do a final quality control check. Quite 
often, we need to work with the authors to correct ambiguities in the 
document, This usually takes another one or two weeks.

Now, to help the community at large know when a new document is posted, the 
OGC will be implementing the ability to subscribe to alerts via RSS whenever 
any new document is posted to the public OGC archives. Arnulf made this 
suggestion and it was unanimously approved by the OGC Planning Committee.

Kind regards

Carl Reed
