PDF TEXT status indicator

I have an Omeka Dev Install with 17 PDF files, about half of them are manuscripts and the other half are OCR'd PDFs. I installed the PDF TEXT plugin to extract the text from them. Upon successful installation I checked the "Process Existing PDF files" and then initiated the process by clicking on save.

I am wondering if there is any way to tell where in the process it is. I went to check on some of the PDFs that are OCRd, but there is no extracted text in the related metadata field.

How long does the extraction process typically take? Some of the files are rather larger (~ 200MB).

There was an issue with non UTF-8 characters in the PDF caused pdftotext to abort the parsing. I have posted a solution here: https://github.com/omeka/plugin-PdfText/issues/5
