Re: [Tiff] Mail archive and tag index
Hi, where is a list of all kown TIFF tags?

Not sure what the community could come up with. One possibility would be to host it on GitLab in a new repository under the libtiff organisation, and generate it using GitLab Pages as we do for the libtiff documentation. We could convert it to use e.g. Sphinx RST and generate the web pages from that. I would be willing to do the work to convert it and set that up if there was agreement this would be a useful way to preserve it and keep it updated over time. And I would like to reiterate Even's thanks to Joris for all of the work he has done; I have found the TIFF tag reference absolutely invaluable over the years, it's a real treasure trove of useful information that has benefitted many people.

Re: [Tiff] Mail archive and tag index
Regarding archive search: I remember enabling this a few years ago for this list, ah I see it must have been back in 2021: https://www.mail-archive.com/tiff@lists.osgeo.org/maillist.html So it doesn't go back to your 1993 archives, but, at least it gives users a way to search a few years... -jeff -- Jeff McKenna GatewayGeo: Developers of MS4W, & offering MapServer Consulting/Dev co-founder of FOSS4G http://gatewaygeo.com/ On 2024-04-24 5:17 p.m., Joris Van Damme (AWare Systems) via Tiff wrote: Hello, I would like to discuss https://www.awaresystems.be/imaging/tiff.html and everything on there.

Re: [Tiff] Mail archive and tag index
Hi Joris, Thanks again for all the work you've been doing for the community! For the mailing list archive, the obvious and easy solution to migrate away from your archive would be to just rely on the mailman archiving that is used for other OSGeo-hosted mailing lists (like https://lists.osgeo.org/pipermail/gdal-dev/), and that had been disabled explicitly for the tiff mailing list. The downside is mailman is that it isn't really searchable (what Nabble used to work around, but is no longer there unfortunately). Anyway if we had access to the raw emails of the mailing list (do you have that?), I presume we could re-ingest that into mailman, and reconstruct a full libtiff archive. In the worse case, we might just re-enable mailman archiving onwards, and rely on the wayback machine to access older threads when needed (my personal experience is that it is very rare that I need to dig into ancient emails not in my mailbox, but newcomers might perhaps find it useful to browse into past discussions occasionally) The tag reference and file format are very useful (I've even seen them referenced from official documents). Not sure what the community could come up with. Still in the worse case, we might crowl the wayback machine if awaresystems.be/imaging/tiff would become available. I guess it wouldn't hurt though if you could dump your source code into some github repo though, despite the potential difficulty of making sense of it and the uncertainties on the licensing of some components. At least that could be a starting point.
