extractBibtexEntry back to summary

extractBibtexEntry	back to summary
public Optional<BibEntry> extractBibtexEntry() Helper function for retrieving a BibEntry from the DublinCore metadata in a PDF file. To understand how to get hold of a DublinCore have a look in the test cases for XMPUtil. The BibEntry is build by mapping individual fields in the dublin core (like creator, title, subject) to fields in a bibtex bibEntry. In case special "bibtex/" entries are contained, the normal dublin core fields take precedence. For instance, the dublin core date takes precedence over bibtex/month. The opposite method is `DublinCoreExtractor#fillDublinCoreSchema()` Returns:Optional<BibEntry> The bibEntry extracted from the document information.
