18:32:43 <Zakim> ok, trackbot
18:32:44 <trackbot> Meeting: Efficient XML Interchange Working Group Teleconference
18:32:44 <trackbot> Date: 13 December 2016
18:41:53 <taki> CB: I talked to CSS team contact, who told me it will be on the telecon agenda.
18:42:05 <taki> CB: I will need to ping him again.
18:47:09 <taki> TOPIC: Empty DTR Map same as no DTR Map?
18:47:45 <taki> DP: EXI stream that use DTRM. in a way there is no types. Empty DTRM element in the header.
18:49:00 <taki> DP: Exificient parsed it correctly. The assumption is that there is no DTRM. Codec fallbacks to the default.
18:49:22 <taki> DP: The encoder expected differently.
18:49:54 <taki> DP: In Canonical EXI as well we say, if DTRM is empty, we can remove it.
18:50:04 <taki> DP: I am not sure spec is clear enough.
19:06:27 <taki> TK: We need a testcase in TTFMS.
19:09:51 <taki> TOPIC: application/exi media-type
19:11:29 <taki> DP: It seems that application/exi media-type is missing from IANA.
19:13:19 <taki> CB: I will contact liaison contact.
19:16:11 <taki> TOPIC: EXI's built-in DEFLATE compression still the best way to go?
19:16:37 <taki> DP: I further tested. ZSTD from facebook and LZMA
19:17:03 <taki> DP: Both don't seem to beat Brotli.
19:17:15 <taki> DP: At least in default mode.
19:19:01 <caribou> https://www.w3.org/TR/WOFF2/ uses Brotli compression
19:21:24 <taki> DP: I looked into CSS.
19:21:51 <taki> DP: I tried some optimizations. I essentially changed the schema so that well-known CSS property names are enumerated.
19:22:26 <taki> DP: I tried to compare the result.
19:23:39 <taki> DP: This difference occurs if you can use strict and enumerated mode.
19:24:20 <taki> DP: We definitely need grammar strings.
19:24:37 <taki> DP: So that the structure is strict but content can be extended.
19:26:57 <taki> DP: I added ZSTD and LZMA in excel.
19:28:08 <taki> DP: I may be possible that those algorithms may work better with EXI.
19:33:25 <taki> DP: Once you use good algorithm like brotli, even EXI bytealigned almost works as good as precompression.
19:35:07 <taki> CB: WOFF2 requires brotli, and only brotli.

19:45:15 <caribou> IPR is clearly covered (https://datatracker.ietf.org/ipr/2396/)
19:49:05 <taki> TOPIC: Efficient XML Interchange (EXI) Extended String
19:50:16 <taki> DP: I was wondering, if it is useful to have a flag to assert there is grammar string is specified.
19:51:10 <taki> DP: For simplicity and performance.
19:52:44 <taki> DP: At "appinfo" level. To indicate the appinfo is for EXI.
19:53:40 <taki> TK: I will add it in section 3.
