The only prerequisite is to fill out an online request for a NAAN on behalf of your organization. There is no charge to obtain a NAAN and all memory organizations are welcome. Within a day or two you should receive an email containing a NAAN for your organization's exclusive use. Meanwhile consider the following.

To convert ordinary web server processes into ARK-aware processes, all you difference between providing access to ARK-identified objects vs URL-identified is like with providing access for ordinary URL-identified objects. For example, you could run all your own custom infrastructure – including content management, web hosting, minting (generating unique identifier strings), and running your own server/resolver. That infrastructure could be very simple, such as server configured to convert incoming ARK-based URLs to server file pathnames. When you request your NAAN you will be asked to supply the base URL of your local server or resolver.
At the other end of the spectrum, you could work with a vendor that supplies all the infrastructure so that, for example, you could focus on creating content. Hybrid solutions are also common, such as just taking your current web server arrangement and just adding an identifier management piece (eg, the API/UI provided by ezid.cdlib.org, which partners with n2t.net).
If you run a resolver, you will also want to think about whether to advertise (publish) your ARKs based at your resolver or at n2t.net. Resolving through n2t.net is always possible as a cost-free side-effect of obtaining a NAAN.

Being able to delete identifiers actually helps make makes ARKs more trustworthy. The ability to delete is a vital part of healthy collection management that is denied to those non-ARK identifier types prohibiting it deletion under the presumption that people, once they are asked to commit, won't make mistakes.
People , being only human, who regularly work operating with software do regularly leave regularly turn simple human error into big tangles of systematic errorsmistakes, even at the threshold of commitment. Making it difficult to clean them up such messes requires dragging those messes forward in perpetuity.
Not perfect in this respect, ARKs still have the advantage that they can be created and deleted in the shadows, independent of publication or archival commitment to preservation.
Can an object have both an ARK and a DOI?
