I'm not sure that it should replace k:more; there are sequences which don't need extra terms, even though few appear, as well as sequences where extra terms are desired even though we already have many. <a href="/wiki/User:Charles_R_Greathouse_IV" title="User:Charles R Greathouse IV">Charles R Greathouse IV</a> 22:23, 21 November 2010 (UTC)</dd> <dd> Like Charles, I believe the "more" keyword is still needed. But I suggest at least 2 "help needed" queues: one with "more", "hard", and non "fini, full" prioritized to induce contributors on working on them. Another with "uned", "obsc" or similar idea (such as ref needed, conjecture to prove, etc.) to induce users to enhance and edit them. <a href="/wiki/User:Olivier_G%C3%A9rard" title="User:Olivier Gérard">Olivier Gérard</a> 06:05, 30 March 2011 (UTC) <dl><dd> It would be nice to distinguish between the various types of 'help needed's. You mention conjectures: I can imagine many types of conjectures, from ones which just need eyes to ones equivalent to major unsolved problems.

These might get a bit complicated for the cases where there are multiple sets of related sequences, each set appearing together in the index in a consistent order (e.g. a group of related sequences for base 2, the corresponding sequences for base 3, etc.), but I think it's the best way to keep the Index up to date whenever corrections are made to sequences mentioned in it. <a href="/wiki/User:Joseph_Myers" title="User:Joseph Myers">Joseph Myers</a> 12:43, 24 November 2010 (UTC) <dl><dd> It's hard to search for these compared to searching for keywords. They're also hard to add: you can just type "mult", but can you remember the wording and the link to linear recurrence relations? Also I have concerns about "related to" vs. "is a member of"; the former is what the index is best at, while the latter seems more suited to a keyword/category/other metadata. We have thousands of linear recurrence relations; it's not practical to browse them directly, not even when broken down by signature. <a href="/wiki/User:Charles_R_Greathouse_IV" title="User:Charles R Greathouse IV">Charles R Greathouse IV</a> 15:10, 26 January 2011 (UTC)</dd></dl></dd></dl></li> <li> Expanded keywords, unless included in the above</li> <li> More information for each keyword: base(10), base(factorial), fini(conjectured), cons(10); these should be standardized in some way.</li> <li> Better integration of b-files: changing a b-file should automatically change the associated sequence terms and changing sequence terms or offset should automatically update the b-file; it should be possible to use a b-file to provide the terms of a new sequence instead of pasting in those terms; b-files should be version-controlled like the sequence entries properly; "full" keyword should apply to the set of terms in the b-file. <a href="/wiki/User:Joseph_Myers" title="User:Joseph Myers">Joseph Myers</a> 21:52, 21 November 2010 (UTC) <dl><dd> Better integration sounds good, but I would be careful here. If a b-file is submitted which does not match the current terms of the sequence, the most likely reason is that the b-file is wrong, not that the sequence is wrong. (For example, because the user uploaded the wrong file or misunderstood the definition.) I don't oppose changes here as long as they retain the error-correcting features of the current version. <a href="/wiki/User:Charles_R_Greathouse_IV" title="User:Charles R Greathouse IV">Charles R Greathouse IV</a> 17:48, 5 July 2012 (UTC)</dd></dl></li> <li> Similarly, automatically processed relations between sequences; if a set of sequences are known to be the same except for offset and initial terms, extending one should extend all of them (and all their b-files); likewise for linear relations between sequences. <a href="/wiki/User:Joseph_Myers" title="User:Joseph Myers">Joseph Myers</a> 21:52, 21 November 2010 (UTC)</li> <li> Some way to describe the density of the sequence, when appropriate: cofinite, density 1, positive lower density, fractional power density, log density, etc.</li> <li> Microformats integration: hCalendar? hCard? Appropriate <code>rel</code> attributes?</li> <li> There should be a <b>more</b> keyword not only for "more terms" but also specifically for "more crossrefs", "more programs" in particular (maybe others).
