![]() It seems all wrapped up in the notion that metadata is itself a kind of intellectual property, not public data. I’m not crazy about the DOI solution however. The software still won’t scan PDFs for you and automatically import the PDF and any associated metadata the way iTunes will when you rip a CD. ![]() Some bibliographic software, such as EndNote, can even resolve DOIs for you.Īt present, when you get to the destination web page you still need to manually make the extra step of download the bibliographic metadata yourself and importing it into your bibliographic software. While your web browser doesn’t (yet) understand a DOI address, you can resolve the above DOI by going to this link, or going to this page and entering the text “10.1146/annurev.anthro.33.070203.143706” in the box. ![]() Like a URL a user can be directly linked to that work via various software tools. Like an ISBN number, it identifies a particular work. In other words, it is like a cross between a web address (URL) and an ISBN number. It will look like this:ĭoi:10.1146/annurev.anthro.33.070203.143706Ī standard for persistently identifying a piece of intellectual property on a digital network and associating it with related current data, the metadata, in a structured extensible way. If you download a recent issue of the Annual Review of Anthropology from the Annual Review web site you will see a DOI link at the top of the document. And this is another part of the problem with PDF metadata: the fact that there are so many different academic search engines, none of which is exhaustive. Some academic websites will let you download citation data – but if the file is already sitting on your hard drive you can’t always figure out what database it came from. But precisely because of this, much less effort has gone into making it easy to automate the entering of such data into databases. Not all songs have their title as the chorus. That you can open a PDF and read the data is a big difference between PDF files and other kinds of media. So, while there are many programs that will let you keep track of your PDF files in the same way that iTunes or iPhoto keeps track music and photos (my favorite is Bookends), one still has to open up the PDF, read the information, and then manually type it in to the database. You are lucky if you can even click inside the PDF file to copy and paste the article title. While songs and photos are rich in computer-readable metadata, most PDF files contain very little. But there is one kind of information that remains in the dark ages: academic texts. When I take pictures with my digital camera it automatically saves extra information about the date I took the picture, what camera I used, and even the aperture and other settings. There is even software that can automatically download the cover art for each album. Software can identify the song and automatically add information about the song title, the artist, album, etc. If you have a few thousand songs sitting on your hard drive there are all kinds of programs which will help you organize and catalog your information automatically. We live in a wondrous era for electronic information.
