4. Absence of Technological Restriction

The work must be provided in such a form that there are no technological
obstacles to the performance of the above activities. This can be achieved
by the provision of the work in an open data format, i.e. one whose
specification is publicly and freely available and which places no
restrictions monetary or otherwise upon its use.
I am not familiar with the details of what OCLC is releasing but it I would
have thought the provider had a duty to make it possible to access all the
content in some way (dumps and iterators are the two things that come to
mind). Do OCLC give an indication of how to get all the data? Because
simply saying "our data is Open but you can't get it" isn't really Open.

I have some sympathy for data providers as I have had to create a set of
crawlers to download Open Data that I have collected. It's a non-trivial
