xml or ris for importing from End Note

I see advice in your documentation to use xml as the file format, while other guides say to use RIS. Is the XML suggestion up to date? Is one safer than the other?
  • Zotero is able to import either.

    Endnote XML is a newer and richer format, so may preserve a bit more than RIS when exporting from Endnote. Endnote XML is likely a better "default" format, but either should bring in 90+% of what you'd like.

    Note that Endnote has made undocumented changes to both of these and not all people store information in Endnote in the same way. This sometimes prevents getting to 100% out-of-the-box. Inspect records that you've imported. If you notice any undesired behavior, it is better to catch them early. Searching these forums may show threads where people have had similar experiences & there may be a work around (e.g. using a different version of the exporter in Endnote, editing the file slightly, or making small changes to the Zotero translator).
  • The main advantage of RIS comes in making the types of changes noksagt mentions, as it's much easier to modify using search&replace.
  • The primary reason XML is recommended as a default is that it preserves any rich text markup in item titles (e.g., italics, bold, etc.). If you don't have any of that, you likely won't notice any difference between the two formats.

    The documentation recommends exporting from EndNote in xml format, but it does not (I'm using x9) indicate what should be specified in 'output style'. Not sure why that option isn't greyed out, but does it matter what we enter there? Any thoughts?
  • When you export a database in EndNote XML (or RIS) there is no relevant style. You are using a selected to export your database records _not_ some bibliographic style.
  • That's what I thought. And why I expected that option would be greyed out. But so ok, that confirms. I was just afraid that the reason why I am now already importing only 5600 items (and yes, sync is off) is already taking over an hour. But I guess patience is in order...
  • I'm afraid import into Zotero is quite slow, yes. There's been talk of speeding that up (and that will definitely happen), but I don't know how far advanced they are on that front.
  • I keep getting an error trying to do this (tried 2 times) - error 296911007. Can somebody please look into this?
  • [JavaScript Error: "out of memory"]
    You should try opening the file up in a text editor (e.g., Notepad) and breaking it into multiple files, and then importing those. (We'll be improving memory usage along with performance for imports in the not-too-distant future.)
  • Splitting isn't trivial with XML, though. Are you able to export smaller bits? Otherwise I can probably tell you what to change to split Endnote XML files.
  • (Oh, sorry, I thought this was RIS.)
  • I have put this issue on the back burner for now. But thanks for looking into this. And I guess I could always export smaller batches from Endnote separately. Are there any rules of thumb for how big these can be for what amount of memory?
  • Nothing super reliable (depends on length of the XML entries and computer memory) but 2k are typically fine on a modern computer.
  • We also have an open issue for reducing the memory usage of EndNote XML import.
  • Any word/suggestions on improving import performance (also for larger collections)?
