Open Letter on the future of miniSeed
2016-08-23 20:06:35 - 2016-08-30 18:30:17
Participants in the discussion on the future of miniSEED International data exchange in earthquake seismology has been effective over decades because, among other reasons, SEED format has been mostly static. There are places in SEED into which everything, albeit awkwardly in some cases, has to fit. This creates a format that everybody may grouse about equally, but lives within. As a result, there has been a remarkable level of data sharing across networks. We were one of the early partic… [more]

Hi all, Apologies for the flurry of emails about change proposals, but ideally we now will have somewhat organized feedback on each of them. I did not include the following two proposals: #4 was to fix a typo in the straw man, which will be fixed. #10 was to accommodate non-integer sample rates in the header. The 2016-3-30 straw man already accommodates this by denoting the sampling rate as an IEEE float. Please let me know if anything is unclear or if I have missed any proposals. We ar… [more]

miniSEED: progress on a new FDSN standard
2016-08-04 22:59:04
Dear Colleagues and Members of Working Group II: I have been observing some of the discussions and exchanges in WGII concerning the efforts of developing a standard for a new/updated miniSEED format. It is clear from these discussions, as well as from input from users, data managers, and equipment manufacturers, that the time is right for FDSN to address -- with a new standard -- the shortcomings of the current miniSEED format. The development, adoption, and promotion of standards throu… [more]
