The output of the sample code is shown to the right. As you can see, the scraper produces a nice fine-grained record of basic metadata. Given an openSearch query channel such as that demonstrated in the previous post, this data can be used to retrieve a copy of the case. With a relatively small amount of work to add a supporting user interface to Multilingual Zotero, one click can call up a list of cases cited in a judgment, and a second can call up the case text itself.
Some further work will be needed to tie this together, but just as site translators provide a uniform interface to disparate content on the Web, client-side citation parsing can provide a uniform link layer on case law drawn from scattered sources. This could get interesting.
