Reported Bugs

  • References with ndash don't get parsed: e.g., [1–6] will not get parsed, but [1-6] will.
  • Parser does not find a title in a .odt when it is in the document properties (Peter Sefton)
  • A large amount of text gets missed in some documents (Peter Sefton)
  • Does not gracefully deal with "et al"
  • Adding author or affiliation goes to error screen
  • Extraneous "Aff1" with nothing attached to it - on first author.
  • Affiliations are numbered by their metadatas ID, not by their sequence.
  • Conflict of interest does not get sent to <back> matter
  • Occasionally random "<name name-style="western">" appear when an article has many, many authors
  • Does not properly output "et al" for citations with more than X authors (6?) (in HTML)
  • Does not at all output <publisher-loc> or <publisher-name>
