Serve DC files via GET requests on DCOR
Project description
This CKAN plugin provides an API for accessing DC data. The python package dclab implements a client library (dclab.rtdc_dataset.fmt_dcor) to access this API. Shape-Out 2 offers a GUI via File - Load DCOR data.
This plugin implements:
The DCOR API for accessing DC datasets online (dcserv).
A background job that generates a condensed dataset after a resource has been created.
A background job that uploads the condensed dataset to the S3 object store. The temporary location of the condensed dataset that is created can be set by setting the ckanext.dc_serve.tmp_dir configuration option.
A route that makes the condensed dataset available via “/dataset/{id}/resource/{resource_id}/condensed.rtdc” (S3 object store data is made available via a redirect)
A route overriding the default route for downloading a resource via “/dataset/{id}/resource/{resource_id}/download/resource_name” (S3 object store data is made available via a redirect)
Extends the template to show a condensed resource download button
CLI:
add CKAN command run-jobs-dc-serve that runs all background jobs for all resources (if not already done)
