- Take some PDF/A validator tools, run them against the test suite, normalise the output, and publish on a web site for general consumption.
- Augment the test suite with files that are believed to be valid.
- The Isartor test files contain text that describes how they break the standard. This text could be turned into machine-readable properties, e.g. RDF, to make testing easier.
- Seek permission to redistribute the corpora items individually, to make analysis and annotation easier. Perhaps OPF members only?
