push command to push material to remote CKAN

[rufuspollock]

push commands sync source package on local disk with remote CKAN (with webstore). Different from upload in that it is more source code like (hg push / git push), designed pushing individual source files to e.g. webstore rather than uploading a tar.gz of built package.

Remarks:

• Need to push resources before metadata because metadata will reference resources
  • What about just using webstorer? Answer: no, because these resources will live in my namespace in webstore and be continuously updated ...

Process:

• Look at directory for a datapackage.json
  • If not found exit
• Look in .dpm/config in current directory
• Find section [remote] and look for url attribute
  • Assume this is CKAN instance
  • Extract CKAN url
• [?? do we need to try pushing metadata at this point to check e.g. name is available?]
• Read resources in datapackage.json
  • For each resource with a local_url
  • If no file exists: continue
  • Decide whether file is pushable to webstore
    • If not print warning and continue
  • Check if webstore_url exists.
  • If not generate it
  • Push to webstore
  • Save webstore_url to resource and write datapackage.json
  • Save url to data (e.g. webstore csv?)
• Push metadata to CKAN instance
  • ...
