If you are a metadata librarian and would like to learn about metadata for social science data, check out the newest issue (April 2011) of DDI Directions, the newsletter of the Data Documentation Initiative. Then, browse the DDI website.
DDI is a specification for documenting social science data (e.g., census data, public opinion polls, economic time series, social surveys, government data, etc.). It enables you to document the entire lifecycle of data: conceptualization, collection, processing, distribution, discovery, analysis, repurposing, and archiving.
