What are the Open Access TDM-prepared datafiles and what are their origin?
The DTU Library collection of OA TDM-prepared datafiles stems from sources that collects Open Access versions of scientific articles to which anyone has the right to do anything with the files without asking anyone for permission. It is typically files in PDF format. DTU Library prepares for TDM by extracting the cleartext from these PDF files into a text file. For each article fed into the collection, the collection will make available both the PDF and the text version. Currently, the collection is based on a single source: PubMedCentral.
How do I download the datafiles from the collection of Open Access TDM-prepared datafiles?
In the metadata export files (CSV), if a publication has a datafile associated from the collection of Open Access TDM-prepared datafiles, a link (URL) to that file will feature in a designated column in the line for that publication. Following the link will download the text version of the publication. Adding the extension ".pdf" to the link and then following it will download the pdf version. The link contain an access token generated as part of the download of the metadata export file. The token is generated based on various information, including knowledge about you, the search you made, etc. The token is time-limited and will expire 24 hours after it was generated.
