The following is copy and pasted (a fair use in this case, I believe) from the link above. It is in reference to USA law:

What is Required for a Compilation to be Eligible for Copyright?

The law identifies three distinct elements, all of which must be met for a work to qualify as a copyrightable compilation:

   1. the collection and assembly of pre-existing material, facts, or  data;
   2. the selection, coordination, or arrangement of those materials; and
   3. the creation, by virtue of the particular selection, coordination, or arrangement of an original work of authorship.

Collection and assembling facts and information isn't enough. Compilations, just as any other work, may only be copyrighted if the originality requirement, “an original work of authorship,” is met.

I think its arguable if the document in the form it was copied to the wiki has sufficient originality to be considered an copyrightable work in the united states. It might be a court would view it as simply a "phone book" style collection of information which was not copyrightable. Given that the content of this document is clearly entirely derived from the code and behavior of Bitcoin in the first place, I hope an agreement is found where this information can legally be incorporated into the Bitcoin documentation because it is obviously useful to the community. Thank you again for taking the time to prepare it and share it - under whatever terms you decide are appropriate.
