The Purdue University Libraries have launched the Data Curation Profiles Directory
Here's an excerpt from the announcement:
Data Curation Profiles (DCP) are in-depth publications which provide detailed descriptions of research data sets and collections. The DCP, and the associated Toolkit which provides instructions and advice on composing them, are the results of research funded by the Institute of Museum and Library Services (IMLS).
Working with Purdue University Libraries Scholarly Publishing Services, the Data Curation Profiles Directory provides a suite of services to support publication, including: assigning a DOI and citation for each published DCP, improved visibility for Profiles through inclusion in indexing and discovery tools, and a commitment to the preservation of DCPs through CLOCKSS and Portico.
