 Based on the experience of operating registries for organisations similar requirements to TC-211, in particular the http://defs.opengis.net/vocprez/[Open Geospatial Consortium's Naming Authority] and the https://cgi.vocabs.ga.gov.au/[Commission for Geoscience Information], we can estimate the following tasks and _rough order of magnitude_ costs for TC-211 to run a registry if using similar tools. 
 
-The tool considered for use is [Prez](https://prez.dev), an open-source product developed for vocab can catalogue information and partly mantained by the OGC for use in its 'Rainbow'. Prez was used to demonstrate a codelists vocabulary register in Dec '22 and May'23. It is currently used widely and it is free.
