# Rule 2. Share your data online, with a permanent identifier.  Nothing really lasts forever, so "permanent" actually just means long-lasting. For example, your personal web site is unlikely to be a good option for long-term data storage (yet, in the very short run, putting your data on your site is better than doing nothing at all!). In general, although many papers include URLs to give access to datasets, most become inaccessible within a few years \cite{Wren_2008}. The best option for releasing your data with long-term guarantee is to **deposit them in whatever data archive is the "go to" place for your field**. A proper, trustworthy, archive will: (1)  assign an identifier such as a "handle" (hdl) or "digital object identifier" (doi); assure (2) require  that you have provided provide  adequate documentation and metadata; and (3)  manage the care "care  and feeding feeding"  of your data. data by employing good curation practices.  If no such archive exists in your field, some there are also  generic (non-domain-specific)  online services will that can  host your data and issue persistent identifiers (see Rule 8). Pointers to a few generic repositories are listed in Appendix A, and longer lists compilations  of such services are at the links in Appendix B.
