Dear Friends

 

We are in need of a PDF Metadata Extractor Information, preferably free and not online. Please share the information if anybody using it. Actually it is for using in combination with DSpace software, but we can not go online with our collection.

Any help will be highly appreciated.

Thank you

Try ExitTool

I have been using it for extracting metadata from PDFs for using in DSpace.  It is possible to extract metadata from all PDFs at one go, if you are familiar with command line options.

Thank you very much sir

But I think the tool is extracting data from document properties in my try. Are you getting the appropriate data with exiftool?

Hi,

Using the below command, you can extract all metadata (i.e. all metadata tags associated with the PDF document) from hundreds of PDF documents and save it as CSV file which could be used for doing batch import within DSpace.  

In case, if you require only specific tags, then you have to mention the required metadata tags for extracting.  I have given an example below for your understanding.

To extract all available metadata tags from the PDF documents and save it as a CSV file

---------------------------------------------------------------------------------------------------------------------

exiftool -csv  *.pdf > output.csv

To extract specific metadata tags from the PDF documents and save it as a CSV file

-----------------------------------------------------------------------------------------------------------------------------

exiftool  -TAG -Title   -TAG -Author  -TAG -Producer  -TAG -Subject -TAG -Description -TAG -Type -TAG -Keywords -TAG -ISBN -TAG -Isbn -TAG -Createdate -TAG -CourseID  -TAG -FileSize -TAG -PageCount -TAG -PDFVersion -d %Y-%m-%d  *.pdf -csv > output.csv

Hope this helps.

Sir

I have checked your software, its a great effort if you have coded it yourself. As I see most of the software(s) are not able to identify the pdf files metadata as we require. I think the problem is mostly revolve around  the structure of pdf files itself. In my case the pdf files are not having any standard structure (+ OCR ) in it for the algorithm to extract as it did for any appropriate one. Since we are in hurry and we require more metadata for the current work, we are thinking of indexing it and filtering it later through various categories. Anyway thanks for your reply.
