Steve,

I understand your concerns and, for me, I think that when we say that there
are some best practices, we are not saying to people to not publish if they
cannot do the best practices. If they don't have a choice, well, it is
better to publish in PDF. But it is not a best practice. It is a practice
better than no practice.

As I was discussing in the thread of 5 stars LOD (as a scale of quality
that is understood many times as the absolute scale of quality of Data
Published on The Web), the LOD scale is not the absolute scale of quality
but it is one of them. But besides this scale, there are other quality axes
that could be enhanced, even using PDFs, for example, good metadata (about
licenses, SLAs, versions, update periods, etc.) good data, etc.

So, IMHO, what we can say to someone that publish in PDF, and have no other
choice, is that the quality of the publication could be enhanced in
different ways, aggregating good metadata for example, etc. And when the
PDF could be replaced by another format, so, do it.

Abraços,
Laufer
