Good morning/evening, In preparation for our call on Monday and per my homework [1], below are data points and thoughts on how to handle the Registration Authority (RA) mentioned in the PNG REC [2]. Couple of data points/assumptions: - the RA defined at [2] is defunct - creating and maintaining RAs (as defined by ISO) require significant bureaucratic overhead and lead time - the next edition of PNG should continue to be published in collaboration with ISO - new chunks will be added in the future - implementers should be encouraged to inform others of the private chunks they define - there will be two PNG RECs: a Core REC [2] and an Extensions REC [3] I suggest the following approach: - remove all mentions of the RA from the Core REC - create a WG Note that lists all private chunks included in neither the Core nor the Extensions RECs. New private chunks are added to the list by simple revision of the WG Note. Each chunk has a link to the defining specification/entity. - encourage the community to submit their private chunks to the WG for additional to the WG Note - informatively reference the WG Note from the Core and Extensions RECs, e.g. "additional private chunks are listed at <link>" - all not-yet allocated public chunks are "reserved by W3C", i.e. they must be defined in the Core or Extension REC - add new chunks to the Core and Extensions REC on a case-by-case basis and through revisions of the RECs. These chunks will typically be public chunks, but exceptionally can be private chunks. Looking forward to the discussion. Best, -- Pierre [1] https://github.com/w3c/PNG-spec/issues/49 [2] https://www.w3.org/TR/PNG/ [3] https://w3c.github.io/PNG-spec/extensions
