+Data Package Manager - New Plan Autumn 2011
+===========================================
+
+
+The two roles:
+
+* dpm as a data *package* manager - like pip, gem, apt-get
+* dpm as a data *source* manager - like mercurial / git / ...
+
+dpm as pure *package* manager
+-----------------------------
+
+Commands::
+
+  dpm search
+  dpm info
+  dpm install
+  dpm publish 
+
+dpm as source package manager
+-----------------------------
+
+Commands::
+
+  dpm clone
+  dpm init
+  dpm push
+  dpm add
+
+Creating source data package from scratch::
+
+  $ dpm init {name}
+  > ask you a few questions
+  Your source data package has been created at ...
+  
+  # create csv
+  $ cp /some/path/to/my.csv data/my.csv
+  $ dpm add data/my.csv
+  $ dpm status
+  Staged files are ...
+  
+  # Now upload
+  $ dpm push 
+  Pushing to ...
+
+Working on existing::
+
+  $ dpm clone {url} {path}
+  ...
+  $ edit some files
+  
+  $ dpm add {changed files}
+  $ dpm push ...
+
+Source package layout
+~~~~~~~~~~~~~~~~~~~~~
+
+Same as normal package but in addition have .dpm directory::
+
+  datapackage.json
+  .dpm/
+    config
+    manifest
+  
+.dpm/config file
+~~~~~~~~~~~~~~~~
+
+Looks like::
+
+  [remote]
+  # ckan url
+  url = http://test.ckan.org/
+
+.dpm/manifest
+~~~~~~~~~~~~~
+
+List of files that we manage and their connection to remote webstore. On push this needs to sync with datapackage.json::
+
+  {resource} 
+      local_path
+      webstore_url
+      state: new, unchanged, changed, deleted
+      syncinfo: {
+          unique_columns:
+      }
+
+
+Questions
+~~~~~~~~~
+
+* Duplication of datapackage.json and .dpm/config and .dpm/manifest?
