Empty DTRM element in the header. 18:49:00 DP: Exificient parsed it correctly. The assumption is that there is no DTRM. Codec fallbacks to the default. 18:49:22 DP: The encoder expected differently. 18:49:54 DP: In Canonical EXI as well we say, if DTRM is empty, we can remove it. 18:50:04 DP: I am not sure spec is clear enough. 19:06:27 TK: We need a testcase in TTFMS. 19:09:51 TOPIC: application/exi media-type 19:11:29 DP: It seems that application/exi media-type is missing from IANA. 19:13:19 CB: I will contact liaison contact. 19:16:11 TOPIC: EXI's built-in DEFLATE compression still the best way to go? 19:16:37 DP: I further tested. ZSTD from facebook and LZMA 19:17:03 DP: Both don't seem to beat Brotli. 19:17:15 DP: At least in default mode. 19:19:01 https://www.w3.org/TR/WOFF2/ uses Brotli compression 19:21:24 DP: I looked into CSS. 19:21:51 DP: I tried some optimizations. I essentially changed the schema so that well-known CSS property names are enumerated. 19:22:26 DP: I tried to compare the result. 19:23:39 DP: This difference occurs if you can use strict and enumerated mode. 19:24:20 DP: We definitely need grammar strings. 19:24:37 DP: So that the structure is strict but content can be extended. 19:26:57 DP: I added ZSTD and LZMA in excel. 19:28:08 DP: I may be possible that those algorithms may work better with EXI. 19:33:25 DP: Once you use good algorithm like brotli, even EXI bytealigned almost works as good as precompression. 19:35:07 CB: WOFF2 requires brotli, and only brotli. 19:38:28 https://www.w3.org/2004/01/pp-impl/44556/show-license#x35662 19:40:27 https://datatracker.ietf.org/doc/rfc7932/ 19:40:52 'informational' 19:43:35 https://datatracker.ietf.org/doc/review-alakuijala-brotli-09-genart-telechat-kyzivat-2016-04-28/ (oops....) 19:45:15 IPR is clearly covered (https://datatracker.ietf.org/ipr/2396/) 19:49:05 TOPIC: Efficient XML Interchange (EXI) Extended String 19:50:16 DP: I was wondering, if it is useful to have a flag to assert there is grammar string is specified. 19:51:10 DP: For simplicity and performance. 19:52:44 DP: At "appinfo" level. To indicate the appinfo is for EXI. 19:53:40 TK: I will add it in section 3. 20:02:55 rrsagent, create minutes 20:02:55 I have made the request to generate https://www.w3.org/2016/12/13-exi-minutes.html taki 20:03:10 Our next telecon will be on January 10. 20:03:14 rrsagent, create minutes 20:03:14 I have made the request to generate https://www.w3.org/2016/12/13-exi-minutes.html taki 20:23:10 n8s has joined #exi 20:41:21 Zakim has left #exi 21:02:19 n8s has joined #exi 21:34:12 n8s has joined #exi
