biblatex 条件打印额外日期

这是biblatex 格式用于在线资源。我有以下 biblatex 配置文件。感谢 Guido 提供的信息。我还\MakeSentenceCase从 Audrey 的回答中获取了一些代码biblatex 中标题的句子大小写。

现在，考虑以下 MWE：

\documentclass[10pt]{article}

\usepackage[style=authoryear,backend=biber]{biblatex}
\usepackage{lipsum}
\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@online{kruse,
author = {John S. Kruse},
title = {Framework for Sustainable Soil Management: Literature Review and Synthesis},
year = {2007},
url = {http://www.swcs.org/documents/filelibrary/BeyondTliteraturereview.pdf},
publisher= {Soil and Water Conservation Society},
location={Ankeny (IA)},
urldate = {2008-08-03},
medium = {Internet},
}

@online{cois,
author={},
title = {Canadian Soil Information Service},
medium = {Internet},
location = {Ottawa (ON)},
publisher = {Agriculture and Agri-Food Canada},
urldate = {2010-06-30},
url = {http://sis.agr.gc.ca/cansis/},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}
\lipsum[1]
\nocite{*}
\printbibliography

\end{document}

在此处输入图片描述

对于第一个参考书目条目，我希望能够urlupdate在我的.bib文件中放置一个映射到额外日期字段的字段。我希望能够使用额外日期字段得出类似

加拿大土壤信息服务 [互联网]。2010 年。渥太华 (ON)：加拿大农业和农业食品部；[2010 年 5 月 19 日更新；2010 年 6 月 30 日引用]。可从以下网址获取：http://sis.agr.gc.ca/cansis/

当声明 urlupdate 时

但事实并非如此。

答案肯定在 biblatex 手册的某个地方，但很难找到。我已经在这个问题上呆了 2 个小时了。

答案1

使用 biblatex 2.0/biber 1.0，您可以更改数据模型。只需将其添加到 latex 可以找到的文件“biblatex-dm.cfg”中：

\DeclareDatamodelFields[type=field, datatype=date, skipout]{urlupdate}
\DeclareDatamodelFields[type=field, datatype=integer]{
  urlupday,
  urlupendday,
  urlupendmonth,
  urlupendyear,
  urlupmonth,
  urlupyear}

\DeclareDatamodelEntryfields{
  urlupday,
  urlupendday,
  urlupendmonth,
  urlupendyear,
  urlupmonth,
  urlupyear}

然后，您可以像使用其他日期字段一样，在 .bib 文件中使用字段“urlupdate”，拆分字段“urlupday”等将位于 .bbl 中，您可以像检查其他字段一样，在 biblatex 格式中检查这些字段。

答案2

一种可能性是使用urldate范围值，即YYYY-MM-dd/YYYY-MM-dd第一个日期是必填项，用于值cited，第二个日期用于updated值。然后，您可以使用字段urlendyear, urlendmonth,urlendday来引用更新值。
