I have identified a number of copyright issues with the report.
First of, the websites terms and conditions do not explicitly release the works under a free license.[1] It seems to be more concerned with misrepresentation than commercial considerations. This implies authors could be persuaded to release their work under a free license. For the purpose of our use, the site should explicitly mention a free license.
Moreover it mentions BSkyB, BBC and ITN as copyright holders of some of the documents. Any migration to Wikisource must filter out such content.[1]
Lastly there are a number of now declassified documents that provide vital evidence to reinforce the reports findings, these too need to be freely licensed.
