The Australian National Data Service has launched two research data services: Identify My Data and Register My Data.
Here's an excerpt from the announcement:
The Register My Data services allow you to register descriptions of your research data. These descriptions are then published in a number of discovery environments. The first of these is the Research Data Australia gateway (to be launched by ANDS in July) which aspires to include any Australian publicly funded data relevant to research and enable innovative cross-disciplinary re-use. Data descriptions registered with ANDS are also fed into other data discovery portals in Australia and internationally, including the big search engines such as Google. The Identify My Data services allocate persistent identifiers to data. These identifiers enable continuity of access even when the location of the data on the internet changes.
