-  And...
+  DataCrate is a specification for packaging research data for distribution and
+  reuse.  DataCrate packages may be distributed as archives with or without
+  compression, and hosted on web sites, as they contain an index.html page that
+  sumamrises the contents of the package for  human readers. For machines, there
+  is a JSON-LD file containing metadata that will aid in the  re-use of the data
+  including licensing, publication dates, parties involved in creating the data.
+  Where possible the terms from schema.org are used for metadata, with other
+  ontologies used where needed.
+
+  DataCrate optionally uses the BagIt data packaging standard which is widely
+  used in libraries and archives and increasingly in research data management,
+  including in recent dicsusions about data packaging at the Research Data
+  Aliance (RDA).
