>> As an aside:
>> I have not heard WGS84 referred to as a dynamic datum before. I do know of several WGS 84 Epochs though. This dynamic datum issue will not be a simple issue to resolve.

> Yes, WGS84 has had 6 "realisations" to date, but these have been refinements to the alignment of the WGS84 ellipsoid. It doesn't account for tectonic plate shift.
>> Personally, I don’t believe that it will be viable for many, many years (if ever) to manage our data within the context of a dynamic data as is proposed by some.
> Storing in the time dependent ITRF or ATRF is a separate issue to what is being discussed in this paper.
>> As a former spatial data manager with a data inventory in the PB, I believe that it is just too impractical currently to use a dynamic datum to control our vast global holdings and software.
> A static datum can be used still. The important thing is we need to know whether we are using static or dynamic and not get them confused.
>> When we consider the widespread, global ignorance of the need to manage and utilse data within an appropriate SRS framework, it is an issue that will not be resolved either easily, or in the short term.
> Yes, very hard problem. One that is very important to solve. Odds of success are tough. Challenge accepted. :)
>> @Standards list,
>> FOR ACTION:
>> We have one spare OGC Membership slot avalable currently.
>> Do we have any objections to Cameron using this slot?
>> If so, please advise this list by 1400hr 24th July 2019 UTC and I’ll start a selection process. If not, I’ll advise OGC of Cameron’s nomination for this slot.
>> Kind regards,

>>> Hi OSGeo standards folks,
>>> I'd like to request access to one of OSGeo's OGC standards slots. From now until the end of the year, I'm planning to help address a problem with web-mapping.
>>> The world is using the dynamic WGS84 datum as it were static - which is resulting in map misalignment problems. This is an international problem, which should be done with the collaboration of the OGC, and I'd like to engage within OGC forums as part of this.
