Identifiers and formatter URL

The ctext system and API uses CTP URNs to refer to textual objects including particular editions of a work, and worksets with corresponding work URNs to refer to all editions of a particular work. I would suggest using the work URNs as the most relevant and stable identifiers, and using the following formatter URL to transform e.g. the work URN ctp:work:huangdi-neijing into the URL http://ctext.org/searchbooks.pl?if=en&searchu=ctp:work:huangdi-neijing listing all editions of that work: http://ctext.org/searchbooks.pl?if=en&searchu=$1 D.sturgeon (talk) 23:26, 14 November 2017 (UTC)

@D.sturgeon: You can actually edit the formatter URL yourself. The URL is a statement on each property. You can find it in the user interface by going to the property-page (ctext work ID (P4517)) and edit the formatter URL statement (one of the boxes at the bottom of the page). How about using http://ctext.org/searchbooks.pl?if=en&searchu=ctp:work:$1 or is double prefix useful? --Tobias1984 (talk) 10:38, 17 November 2017 (UTC)

@Tobias1984: Thanks Tobias. Yes, I did find the location and realized that in principle I should be able to edit it myself, but in practice because my account is new I cannot do this as attempting to do so gets me a "Disallow new editors from changing formatter URL" error - so if someone else could make this change for me that would be very helpful. The main motivation for including the "ctp:work:" prefix is that the complete identifiers including this part are used in many other contexts (e.g. can be searched directly within the ctext.org user interface, used to load textual objects into other tools, etc.), and so it seems to me preferable to use the complete meaningful and well-defined identifiers rather than removing the prefix and recording something new and potentially ambiguous. There are also ctext URNs that do not begin with "ctp:work:", but they refer to different objects, and it is generally the case that if there exists an identifier "ctp:work:xxxx", there will also exist a corresponding identifier "ctp:xxxx", though these conceptually refer to quite different things. So I think it would be less confusing to include the prefix, particularly as in contrast to the initial examples, the majority of URNs are not human readable (e.g. "ctp:work:wb601464").

@D.sturgeon: I changed the formatter URL now and changed the values that I added so far. --Tobias1984 (talk) 13:49, 18 November 2017 (UTC)

如何获取ID？

我发现Q30007056对应的标识符不符合 正则表达式，但在www.ctext.org 又找不到对应的标识符，请教一下，是如何找到对应原本的标识符？--Bangbang.S 01:27, 26 February 2022 (UTC)
