Here's a really interesting study getting at the issue of metrics for metadata quality evaluation, and in the course of applying their metric to a large microbial genome database obtain some actual data of which metadata researchers provide, in this case for microbial genome and metagenome sequencing studies (which is covered by the MIGS minimum reporting standard).

I'd imagine Elliott would be quite interested in Table 1.
