Automated extraction of information from standard PDF forms

I have over 2,000 PDFs that I need to extract information from. This requires parsing the PDF and populating known fields. There may be one or two “standard” forms (ie it might not always be the same form, but there are very few variants). Ideally, the program could extract data from documents which are scanned (ie a scanned fax) however if it only works with embedded text PDFs that is acceptable. Ideally the program will be written in Python, however if there is a compelling reason to write in another language I am open to alternatives. Fields required (as per example document): Company Name, ACN 1) Substantial Holder name, Substantial holder ACN, Change in interest date, previous notice date, previous notice dated 2) Previous Notice Persons votes, previous notice voting power, present notice persons votes, present notice voting power 3) Date of change, person whose relevant interest changed, nature of change, consideration given in relation to change, class and number of securities affected, persons votes affected 4) Holder of relevant interest, registered holder of securities, person entitled to be registered as holder, nature of relevant interest, class and number of securities, persons votes 5) Changes in association: Name and ACN, Nature of Association 6) Addresses: Name, Address Many will contain an appendix – I do not need to collect any information from these as they are not standardized.
