Change requests are accepted from any interested party. Change requests should clearly state what is being proposed. If the change is to existing Dataset content then the code for the entity in question must be stated, preferably along with its name. If the request is to add new data then as a minimum the information tabulated in Guidance Note 7-1 annex A must be given (a template for data submission may be downloaded from here. An example has been provided and may be downloaded from here ). This minimum information shall be included in the message to "EPSG feedback", or given indirectly by providing in the change request message the URL for a publicly-available web site which contains the information.
Requests received will be acknowledged by the IOGP Geodesy Subcommittee, normally within one working week of receipt. If they are within scope they will be allocated a change request number and then reviewed by the Subcommittee. The Subcommittee may require the proposer to provide supplementary information before reaching a decision. Changes that are accepted are first made in an unpublished copy of the Dataset and are put through a quality control check. Correspondents may be asked to comment on draft entries. The Subcommittee aim to process all requests within one release cycle of the Dataset. Correspondents will be advised of the decision reached as soon as it has been made.
