+## Licenses
+
+We are storing license texts. This is for several reasons:
+
+* Analysis and review
+* Preservation (and caching)
+
+**Note: not all licenses we list will be Open Definition conformant as we
+include licenses that are under discussion or some non-conformant licenses for
+preservation purposes.**
+
+Approach:
+
+* Store licenses as markdown files
+* Store licenses in `/licenses/`
+
+      # conformant licenses
+      /licenses/conformant/{license-id}/{license-full-name}.md  
+      # licenses under review
+      /licenses/inreview/{license-id}/{license-full-name}.md
+      /licenses/nonconformant/{license-id}/{license-full-name}.md
+
+Notes:
+
+* license-id should be a short url-usable name e.g. odc-pddl or cc-zero
+* Do not put a version in the license name unless is a differentiating factor (e.g. gpl-v3.md)
+  * We use github revisions to track changes (and you can use github tags if needed)
+
+Example, suppose we were storing the Open Data Commons Public Domain Dedication and License.
+
+    /licenses/odc-pddl/public-domain-dedication-license.md
