#1711: Resource validation page

icmurray — Thu, 26 Jan 2012 14:55:59 GMT

On the resources tab, there's a "Check Resources" button which, when clicked makes an ajax request with the list of URLs entered by the user.

The server checka each link for errors and header information about the linked resource. (Using ckanext/archiver/tasks.py:link_checker()).

The server returns a list of dicts (json), containing information about the linked resource, and the client uses that to:

populate the format field of each resource

The (guessed) 'file_extension' populates the 'format' field. If it's 'htm' or 'html', then we assume it's a listing page, and so don't populate the format field with 'htm' or 'html'.

provide feedback if a URL appears to be invalid

If the URL doesn't appear to be a URL at all, or returns a HTTP error, or times-out, then URL field is highlighted in red to indicate it's a bad URL. A tooltip shows the error message to the user.

[Optional] provide feedback if a URL appears to point to "Additional Information" - ie the Resource should be entered under "Additional Resources", rather than "Timeseries" or "Individual" datasets.
