It would be helpful if there were some standard formats for the data sets that are posted on data.gov. It would make it easier to create mashups and to integrate data across data sets. In addition, standards for key fields are needed.
As the Dublin Core proved - a little bit of standardization can go a long way. In the open gov data arena, a short list of the areas it would make sense to have global standards on would help all governments and citizens get clear on what needs to be developed for voluntary adoption and where we develop the standards. This idea is to openly develop that short list so we can accelerate this transformation.
