PHK and others make good points, but I’m still trying to get past the "binary-file equivalent of XML”. I doubt this is worth much more investigation from this group, but in addition to git:
https://github.com/Matroska-Org/ebml-specification there are a few links from the wikipedia page: https://en.wikipedia.org/wiki/Extensible_Binary_Meta_Language including something resembling an RFC from at least as early as 2004. Nobody appears to have written an actual RFC during that decade. The git repository appears recent. One suspects this is just somebody noodling around. Meanwhile there are other RFCs on binary time representation: https://tools.ietf.org/html/rfc4049 https://tools.ietf.org/html/rfc6019 And on efficient (however you want to interpret that word) binary representation in general: https://tools.ietf.org/html/rfc7049 Including wrapping back around to the ITU: http://www.itu.int/en/ITU-T/asn1/Pages/introduction.aspx No surprise that time itself was an early internet discussion point, albeit with more questions than answers: https://tools.ietf.org/html/rfc28 Rob _______________________________________________ LEAPSECS mailing list LEAPSECS@leapsecond.com https://pairlist6.pair.net/mailman/listinfo/leapsecs
