We can use that data to construct a bibtex entry. We do that by defining a template, and filling it in. I wrote this template expansion code which makes it easy to substitute values like %{} in emacs lisp.
Now we define a function that fills in that template from the metadata.
+As different bibtex types share common keys, it is advantageous to separate data extraction from json, and the formatting of the bibtex entry.

* Updating bibtex entries
I wrote this code because it is pretty common for me to copy bibtex entries from ASAP articles that are incomplete, e.g. no page numbers because it is not in print yet. I wanted a convenient way to update an entry from its DOI. Basically, we get the metadata, and update the fields in the entry.
doi:10.1021/jp047349j
+
+* Getting a doi for a bibtex entry missing one
+Some bibtex entries do not have a DOI, maybe because they were entered by hand, or copied from a source that did not have it available. Here we develop some functions to help you find the DOI using Crossref.
+
+Here is our example bibtex entry.

+
+The idea is to query Crossref in a way that is likely to give us a hit relevant to the entry.
+
+According to http://search.crossref.org/help/api we can send a query with a free form citation that may give us something back. We do this to get a list of candidates, and run a helm command to get the doi.
