Producing PDF/A
We have an EWADE Archiving Strategy!
Starting with EWADE 2013, documents are
stored in
PDF/A and are archived in
Zenodo.
Zenodo is a repository made available by the European Union.
With PDF/A and Zenodo documents should be available, discoverable, and reproducible for the next decades (or even centuries):
Creation of PDF/A
Authors ...
- ... should produce simple text with pictures (e.g. no videos included),
- ... should produce well structured documents,
- ... should avoid transparency,
- ... may not protect their PDF with a password,
- ... are allowed to use links pointing within the PDF,
- ... should avoid outside web links (unless pointing to persistent links like DOIs).
The best would be to produce (tagged) PDF/A-1a
(Part 1: ISO 19005-1:2005 Level a or b).
If this is not possible, authors should produce PDF/A-1b.
Only in cases where transparent colors can not be changed anymore in the original document,
PDF/A creation needs to be done with PDF/A-2b
(Part 2: ISO 19005-2:2011 Level b;
ISO 32000-1:2008).
Authors who can not provide PDF/A conforming PDF documents, should provide also the original file (e.g. *.doc, *.ppt).
Conversion to PDF/A directly from the Office Software is preferred. It seems to produce PDF/A with only few errors.
E.g. in PowerPoint select "Save As" and click on "Options" in the dialog box. Select "PDF/A" under "PDF options".

Conversion to PDF/A from PDF tends to be problematic and is only the last resort:
Verification of PDF/A for files directly created or converted:
