Brian Westra et al. have published "Selected Internet Resources on Digital Research Data Curation" in the latest issue of Issues in Science and Technology Librarianship.
Here's an excerpt:
In order to present a webliography of reasonable scope and length, the authors focused on resources applicable to the broader topic of digital research data curation as they relate to the natural sciences. Materials primarily or solely devoted to medical informatics, social sciences, and the humanities were not included. However, it should be noted that a number of the resources presented here are also applicable to research data curation in disciplines other than the sciences—for example, data repository software may be as useful to the social scientist as it is to a researcher in ecology. Additional scope specificity, when necessary, is provided in respective section listings below.
