#235: Resource format normalization and detection

dread — Mon, 18 Jan 2010 15:13:24 GMT

Try to gather proper MIME information for all package resources in CKAN. This is a shared ticket with dcat-tools (https://bitbucket.org/pudo/dcat-tools), i.e. opendatasearch.org. This can then also be used by ckanrdf, the CKAN RDF conversion service.

Sub-tasks:

Create a Google Spreadsheet with two Worksheets: "MIME-Mappings", i.e. "CSV" -> "text/csv" and "Name mappings", i.e. "text/csv" -> "Comma-Separated Spreadsheet".
Collect and map surface forms from all CKANs
Access this via Swiss and apply, store as a PackageResource? extra field pending #826 (Resource extras).
Add heuristics for format auto-detections:
- Map well-known file extensions
- Recognize obvious magic (Zip, Tar)
- Peek into Zipfile/Tarfiles?
Define a convention for generic data types (many CKAN packages have only "Spreadsheet" defined, either detect specific type or set MIME to */tabular-data or similar)

#1069: Stub datasets (request for datasets)

rgrp — Fri, 01 Apr 2011 14:08:39 GMT

Idea is to have stubs for datasets that someone wants but don't yet exist (or haven't been discovered) in the way one has stub pages on a wiki.

We could do this within the existing model by a slight 'abuse' - create a dataset and mark it with a special tag e.g. todo.does-not-yet-exist or similar ...

(Just as we have datasets listed that exist but aren't available ...)

Alternative would be to have a request for datasets subsystem.

I prefer the stub dataset model because it's simpler, provides a simple workflow (as a dataset is found or comes into existence), and the package page provides a natural space in which to accumulate information about what is wanted and what exists.

Implementation

Agree a new dedicated tag. e.g. todo.does-not-exist
