Michael McCandless commented on LUCENE-1799: -------------------------------------------- {quote} > Is there any reason not to make BOCU-1 Lucene's default encoding? in my opinion, just IBM :) {quote} But... ICU's license is compatible w/ ASL (I think), and includes a working impl of BOCU-1, so aren't we in the clear here? Ie we are free to take that impl, tweak it, add to our sources, and include ICU's license in our LICENSE/NOTICE? > Unicode compression > ------------------- > > Key: LUCENE-1799 > URL: https://issues.apache.org/jira/browse/LUCENE-1799 > Project: Lucene - Java > Issue Type: New Feature > Components: Store > Affects Versions: 2.4.1 > Reporter: DM Smith > Priority: Minor > Attachments: LUCENE-1799.patch, LUCENE-1799.patch, LUCENE-1799.patch, > LUCENE-1799.patch, LUCENE-1799.patch, LUCENE-1799.patch > > > In lucene-1793, there is the off-topic suggestion to provide compression of > Unicode data. The motivation was a custom encoding in a Russian analyzer. The > original supposition was that it provided a more compact index. > This led to the comment that a different or compressed encoding would be a > generally useful feature. > BOCU-1 was suggested as a possibility. This is a patented algorithm by IBM > with an implementation in ICU. If Lucene provide it's own implementation a > freely avIlable, royalty-free license would need to be obtained. > SCSU is another Unicode compression algorithm that could be used. > An advantage of these methods is that they work on the whole of Unicode. If > that is not needed an encoding such as iso8859-1 (or whatever covers the > input) could be used. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
