We need to be able to do the following:

• Rip the localised strings from the JavaScript? source code. These are strings that look like _('String'), translate('String') and isPlural('String') .
• An endpoint that provides the translations in the correct locale for the user.
• The endpoint should provide the locale as JSON (possibly using ​http://jsgettext.berlios.de/doc/html/po2json.html or similar tool)

The JavaScript? can then read this file on page load.

When a package's name is changed, references to the old name (in the WUI and REST) are redirected to the new name (assuming the old name is not being reused by another package).

Often people who are registering resources want to make the associated material available. We should:

• Provide a dedicated upload page giving instructions as to upload process
  1. Explain we don't store the data itself on CKAN. Suggest uploading to a store somewhere and then linking using download_url (that is its purpose)
  2. Upload to
     • Talis CC for RDF
     • archive.org
     • grid.okfn.org
• link to this page from next to download_url item on new package page

In long run (now ticket:186) we may automate this by providing a ckan upload facility which caches the data and then reuploads it to relevant service (disadvantage is "we" are the owner of the data on that service ...)

Summarise final set of requirements for this and finish development and test. Estimated 10 working days.

Changes to publishers for customer

Need proper user stories but ...

Publisher admins/editors may need a more useful group read page showing things like:

• The current search

• Recent activity

• People within the group

• Followers

• Others?

'Publisher' entities in the model. They are hierarchical.

'User-Publisher' connections with one or more roles (e.g. drafter, moderator).

Authorization settings can control who can set what values in a 'published by' type field.

Publishers and User-Publishers available to read in the API.

Future tickets will provide:

• API to write Publishers and User-Publishers
• UI to edit Publishers and User-Publishers

(This feature deprecates authorization groups)

Super #1669

Implement authz for sysadmins in publisher profile

Estimate: 4-5d

Only sysadmins can manage harvest sources right now, we need to allow publishers to handle their own sources.

We need to decide if there will be two different profiles on ckanext-harvest, the current one with only sysadmins allowed to manage the harvesting and a new one supporting publishers (ckan core can be configured to not use the publisher model)

Tasks include:

• Auth checks on the different controller actions (and the command line interface?)
• Modify the index page to just show sources the logged user has permissions on.

(Talk with Ross about the specific functions to use)

• Create/edit form to show a dropdown with the user available publishers.

As A

Administrator

I want to

Purge a deleted package

Notes

• this need only be possible via the admin interface

Since we upgraded to new vdm (v0.4) which has built in purge support existing purge support looks to be broken. Should be reasonably easy to fix this.

Cost: 1h

Also configure hmgckan, hmgapi, test-hmg and dev-hmg machines.

Put docs on ReadTheDocs? instead of eu13.

Current write method just creates a bare bones package and does not write any of the available metadata other than name.

Super: #1594

From Richard Cyganiak on the CKAN Discuss list:

Regarding the fifth star (is the dataset linked to others?). This cannot be automatically determined just by looking at the format. It either requires inspection of the actual data, or information about links in the metadata. As you're probably aware, we've established conventions for recording information on data links in CKAN [1], as part of the work of the lodcloud group on the Data Hub. Link information is captured for hundreds of datasets. I would claim that we have the majority of four-star datasets covered there, and hence you can determine if they should get the fifth star by checking for the presence of a links:xxx field.

The extension needs upgrading:

No module named webstore.database

The other option is to delay this functionality and merge with the publisher dashboards after the group refactor.

John, David Raznick, David Read, Ira, what do you think?

Super: #1594

• qa/{username}
• qa/{groupname}
• paginate QA results
• search / filter QA results
• list organisation report by default, but can disable via config option (done)
• UX tidy up of report pages - hide border if no sidebar, etc

Provide RDF version of a package at the RDF URI: ​http://ckan.net/package/rdf/32000-naples-florida-businesses-kml

See email on OKFN help:

For the information to be Linked Data, the following URI (from the api.talis.com SPARQL call) should be resolvable to RDF, or an RDFa enhanced HTML page.

From: Pierre-Yves Vandenbussche

In my use case I need to fetch every sparql endpoint associated to a dataset. With the previous version of your endpoint, I was doing this query: SELECT DISTINCT ?dataset ?endpoint ?title ?identifier WHERE {

?dataset <​http://www.w3.org/ns/dcat#distribution> ?distribution. ?distribution <​http://purl.org/dc/terms/format> [ <​http://moat-project.org/ns#taggedWithTag> [ <​http://moat-project.org/ns#name> "api/sparql" ] ]. ?distribution <​http://www.w3.org/ns/dcat#accessURL> ?endpoint. ?dataset <​http://purl.org/dc/terms/title> ?title. ?dataset <​http://purl.org/dc/terms/identifier> ?identifier.

} ORDER BY ?title

Using your new version,dcterms:title of a dataset is now a rdfs:label ... OK

Unfortunately, I don't have the information of "api/sparql" anymore. So I can not differentiate between a dump file and a SPARQL endpoint...

Add the required information to the RDF template.

This is caused by editing a package with resources over the REST interface.

Thanks to Friedrich for spotting this.

On ckan.net there are a few packages which cause a 403 exception when you try to rate them: ​http://www.ckan.net/package/rate/coins-data?rating=3

The exception is occuring here: ckan.rating:39 in set_rating rating_obj = rating_query.one() InvalidRequestError?: Multiple rows returned for one()

It looks like this package got rated twice in quick succession, creating two similar PackageRating? objects. This race condition needs to be solved and these particular rating objects repaired.

Occasionally see this problem when producing an error page. Here's an example

Background

In the Web UI, when you rate a package it simply links to something like:

​http://ckan.net/package/rate/mke-liquor-licenses?rating=3

This creates a GET request.

This is bad because:

• Search engine crawlers follow links to find pages, and in this case end up creating a rating (although we've got a robots.txt to try and avoid this)
• There are occasions when we want to make a CKAN instance read-only, so we put a <LimitExcept? GET> Apache instruction in. But the database may still get written for these ratings.
• Best practise for web requests is for GET to be a read-only request.

Schedule worker calls to be ran several times, with certain intervals.

Whilse using CKAN web interface, you are not tempted to edit stuff:

• You know at all times this CKAN is read-only
• All editing facilities are still seen but greyed-out with an indication why it is.

CKAN should have a read-only maintenance mode with a nice little banner on all pages, appropriate REST messages etc. Bonus points if this is triggered via an environment variable and thus can be triggered by the surrounding apache.

Admin configures entering read-only mode in one of two places:

• CKAN config file (e.g. ckan.ini)
• environment variable from Apache config

Once enabled, no writes can occur to the database (including user ratings and other usage stats).

For EC Portal need a page (or HTML snippet embedded in the front page?) listing recently added or updated datasets.

• Could be generated from the activity streams

• Should it list datasets only, or other activities as well?

• May be related to #1785 (Replace 'Revisions' page with site-wide activity stream)

Opera cannot show a recline preview. I shows 0 records.

• Number of package page visits on ckan (can we get this straight from google analytics)
• Number of times url or download url is used - now ticket:937 (Record download stats for resoures)

How do we do this?

• Google analytics will miss a lot of this usage (and how do we get that data out anyway)
• Could use javascript but again misses usage.
• One option is to redirect link but that is kind of nasty (but may be only option ...)

Use story: As a user of the datasore I want to be able to put the resource id without the dataset name in a url and see the resource page.

Proposed redirect:

/resource/{res-id} -> dataset/foo-bar/resource/{res-id}

This ticket depends on #2423, #2424, #2425, #2426 and #2427.

• Try to remove as many of CKAN's dependencies as possible

• Try to update as many of the remaining ones as possible

• Try to get rid of some dependencies that are fetched from random hg or git servers instead of pypi

• Then try to get the order of deps in the requirements files right so that you end up with the right versions of everything

• Each module in the dependencies file should specify the exact version, to protect us from changes due to them upgrading versions under us and breaking things or changing their own deps

• Consider shipping dependencies with ckan instead of pip installing them?

• This is related to moving CKAN to Ubuntu 12.04

• Add a test case that runs pip freeze and tests that all the right versions of deps are installed?

Estimate: ?

The 4store Sparql endpoint has been down for a long time. It needs to be reenabled and we need to check that the necessary informtion is pushed when creating /editing a dataset.

• Requires Package Read to not use the side-bar
• Need to sync params to a package object that is taken out of the session so that it doesn't go into the database.

Extra fields should be represented in some manner.

Take the resource archiver (currently part of ckanext-qa) and make it into a standalone extension that works as a celery task.

Suggestions from rgrp:

• Get rid of Roles, and replace them with direct assignment of actions, even though there are many actions, and extensions can add arbitrary ones.
• Debatable whether we should cut the number of actions to correspond to the three roles defined by the base system.
• Have a method of finding roles (or, in future, actions) relevant to a given protection object (e.g. FILE-UPLOAD(ER) not relevant to Packages)

(This ticket is split off from #1065)

There is code to create packages in-process (ckan/lib/importer) and via HTTP (ckanclient/loaders/base). There is also code to read different kinds of package source (Google Spreadsheets spreadsheet, other spreadsheet).

Propose to refactor all this to have template method in base command class (subclasses may implement command line interface, graphical user interface, or Web interface), where the template method calls on aggregated strategy objects for: reading raw spreadsheet data from spreadsheet application; for inferring CKAN package entities from the raw spreadsheet data; and for writing package entities to CKAN service.

Spreadsheet readers to be factored to allow for variations of spreadsheet application.

Raw data inferrers to allow for variations in spreadsheet cell structure.

CKAN writer strategies to allow for either CKAN client or direct linking.

Actual cases then supported by specifying existing strategies (or defining new ones) in a script that invokes the command class.

• (Load cli commands from setuptools entry point name datapkg.cli)
• Document how other can write new commands
• Refactor base Command class to support this pluggability (if necessary)
