It seems that searching for extras_foo:value works with solr, but extras_foo.bar:value doesn't. No theory on why.

The default package form offers 4 empty extras fields. Like the resource section, it should have an "add more" button to add another row.

We are getting more and more spam on ckan.net and we need to improve our strategy of combating it. It is bad because google ranks who we link to (which we do want for legitimate links), and our front page contains the latest package edits, so spam is immediately very visible.

Spam:

• Package creation
• Package edit
• User creation
• Group creation

Systems to consider:

• Automatic
  • captcha
  • bayesian scoring
• Sysadmin
  • a tool to quickly analyse and remove packages, edits and users
• Helpful users
  • button to click indicating spam, leading to any/all of:
    • add TODO item (which emails package admin and sysadmins)
    • quarantine the package/user so it doesn't show up on the front page and a warning is shown when you view it

General thoughts:

• We should learn from the wikipedia tools, as they are the experts
• This is a serious problem that is only going to get worse and is a threat to the whole site.

Make a robust way to make sure the drupal database is consistent with the ckan data.

We agreed on a system that allows overriding the authz checks at a logic function level (e.g. package_create, user_show) and supports the old (current) authz system.

Inline with general naming policy going forward.

Currently have this script section put in for i18n. It shouldn't be.

<script type="text/javascript">

(function($){
    $.fn.ajaxCreateSlug = function(name, url) {
        var title = this;
        var updater = {
            init: function(title, name) {
                // Add a new element where the validity of the package name can be displayed
                this.name_field = name;
                this.title_field = title;
                this.name_field.parent().append('<div id="package_name_valid_msg"></div>');
                this.title_field.blur(this.title_change_handler())
                this.title_field.keyup(this.title_change_handler())
                this.name_field.keyup(this.name_change_handler());
                this.name_field.blur(this.name_blur_handler());
                this.url = url;

Put docs on ReadTheDocs? instead of eu13.

Here is Rufus' plan for ckan.org reorganisation from ​http://ckan.okfnpad.org/documentation (22/7/11) (ticket made by dread):

/solutions
  /overview <--- current 'about' page (the software)
  /customers <-- say "in addition to our clients..."
  /features <-- needs most work (pictures etc)
/pricing/  <-- simplest thing possible ... talk with Ira (cover pricing and support)
/developers <--- links to http://docs.ckan.org/, getting the software, the wiki, the mailing list /contact
/blog

Tasks:

• add tagline in header - "the data portal software"
• make and add glossy PDF
• change "data hub" to "data portal" passim (if only using one term)
• add info@…
• image banner on home page - redo screenshots without menus

If someone who is not logged in clicks on "Upload Data", they are presented with

    Not authorized to upload files.

This is in emboldened red text. That is, the system is telling a user that they're doing something illegitimate, even though they're actually following an invitation from the main menu.

I propose two options for resolving this:

1. only display the "Upload Data" tab if someone is authorised to upload data
2. if someone isn't logged int, provide a nice welcome message thanking them for wanting to upload data, but we only allow registered users to do so

ENV: thedatahub.org, CKAN 1.4.2b

Produce a video explaining some of the things which can be done on the datahub.org

Tracked this to issue in dictization/model_save whereby was ignoring case where Package Tag already there but in deleted state. Rather than describe at length see fix.

As a user I want to view a package at a given revision:

• When I visit /package/osm@yyyy-mm-dd or /package/osm@rrrrrrr I should be shown package at date yyyy-mm-dd or revision rrrrrrr.
• viewing this page, it should say it is the old revision, just like wikipedia
• package history page should provide links to these pages

Needs tests for error conditions for bad locale and redirect parameters.

Child tickets:

• #1194 "Welcome back" message for newly registered user
• #1202 Links to datapkg utility don't lead to info about it
• #925 Change the search box icon to remove the down arrow
• #923 Search box doesn't work in leaderboard page in stats extension
• #1034 Flash message cached
• #737 Markdown syntax summary page
• #811 Extra field editing form layout breaks when there are long field names

Dgu tests failed as harvesting table are not created at the correct point.

When there are errors when logging into OpenID, these don't get displayed. You just get the login screen again.

Change the color of the "History" tab icon to yellowish, like the rest of the icons in the other tabs ("View" and "Edit", "Authorization").

Reasoning

When you view a data package, for instance ​http://ckan.net/package/thesaurus-w, you will see "View", "Edit", "History" tabs on the top. "History" tab has a black-and-white icon which makes it look like an inactive/disabled tab (since the text is also grayed out when the tab is not selected). This is not a major issue, but it is a little bit confusing for the users. This icon exists in v1.3.2 and also in v1.4.1a (that runs on ckan.net).

The simple solution would be to change the color of the "History" tab icon and give it the same yellowish color like the rest of the icons in the other tabs (e.g. "View" and "Edit").

I'm not sure if this was reported earlier, but I have found a minor bug in the "Add new package" form. As far as I can see this bug exists in v1.3.2 and also in v1.4.1a (that runs on ckan.net). This is a problem with adding new resources in "Resources" section. To reproduce the bug do the following:

1. Go to "Add new package", for instance ​http://ckan.net/package/new
2. Scroll down to "Resources" section.
3. Click on "Remove this row" link (red circle).
4. Say "Yes" to "Are you sure you wish to remove this row?"
5. Now there should be no rows. Only the header "URL* Format Description"
6. Click on "Add row to table"
7. All you get now is another row with table header "URL* Format Description". You will not be able to add any resources now. Solution is to reload the page.

The simplest solution to this bug will be to hide the "Remove this row" link if there is only one row.

When package does not exist in ckan catalogue, ckanclient.package_entity_get should raise more specific exception, such as CkanNotFoundError? instead of generic CkanApiError?.

When upgrading database for cz.ckan.net (psql.okfn.org/cz.okfn.org) an error occurred (see below).

cz.ckan.net has been running on eu3 and this updrade was part of moving it to eu19, with a more recent version of ckan.

In the meantime I've reverted the db to the old version (pre-upgrade).

cz.ckan.net is not working properly until this is fixed.

I've installed the Moderated Edits extension (ckanext-moderatededits) and am editing a package imported from IATIregistry.org, with an extra field which contains a bit of HTML.

The editor indicates the field has changed, although the content hasn't (see screenshot). All I can find so far is a minor difference: in the field content, there is a code &#8212 and in the rendered table that is an —

Simplify the logic in the atom feed an make all feeds use logic layer to return lists.

We need an email function in CKAN to accept messages sent to users. The basic signature will be:

• mail_user(user_obj, subject, body, mime_type='text/plain', headers={})

This has a number of use cases:

• Retrieval of lost passwords
• E-Mail confirmation

Finally, the mail function should be exposed in the API for sysadmin clients. This way we can have scripts traverse CKAN for 404s, invalid data or missing fields and ping users about that automatically (requires traversal by revision, not package, to get the associated users).

Implementation

Note we have already written code like this (*and* tested it) in isitopen:

• ​https://bitbucket.org/okfn/isitopen/src/bb2cbd146fa5/isitopen/lib/mailer.py
• ​https://bitbucket.org/okfn/isitopen/src/bb2cbd146fa5/isitopen/tests/lib/test_mailer.py

A new library, ​guiders.js, has been open sourced that seems to be great at unobtrusively introducing new users to features of websites.

The library drives Optimizely's website. The GitHub repo is here: ​https://github.com/jeff-optimizely/Guiders-JS

Some examples:

We've seen exceptions caused by people getting the file storage link wrong, adding a slash to the end.

e.g. ​http://ckan.net/storage/f/file/e696d857-e997-41c8-be08-408697168ca8/

We should aim to handle all requests better than causing exception. 404 (or even 302 in this case) is better than 500.

The new formalchemy stores dict in a new format.

Create/register a user with a unicode character in the password. It creates the user, but the redirect to the user page doesn't work and results in 500 error.

​Spideroak is a bulk storage platform by a company that releases quite a lot of ​free software, has an extensive ​developer API with pricing of $10/100GB/month.

The data store is optimised for bulk data storage and retrieval. This is the kind of use case that CKAN packages require. We don't need low latency. We are after low cost, high reliability solution.

When you edit a user, you should be stopped from putting links in the 'about' field, because this is a common tactic by spammers.

Administrators have "View", "Edit" and "History" tabs. However, I can't see a way to delete a package from the web UI.

Version: CKAN.net as of today

The "Preview" button is a nice idea, but it doesn't seem to actually "preview" anything if the file MIME type would ordinarily cause the browser to download the file. If so, the browser does indeed just download the file.

This is notable in the context of most hosted file services (including Google Storage) which will deliberately serve a MIME type of application/x-some-junk-here in order to force a download.

When viewing a user and a package, the about/notes fields contain Markdown, which may have links. These should have rel="nofollow" to discourage link spam.

A small number of tags are near-duplicates of each other.

Perhaps we could support word stemming from NLTK and/or manual tag aliases:

Hi, I get a 500, Internal server error when I enable ckanext-stats. Flavio

/api/rest/package/foo.rdf should return a DCat representation of the package. To create it, we will use the functions in ckanext-rdf.

Some sort of citation helper. Something small on the dataset and resource page that would show how to cite.

wwaites: Some related thoughts on this from opb: ​http://homepages.inf.ed.ac.uk/opb/papers/ssdbm2006.pdf

timclicks: I'm looking at Dataverse for the first time[0]. It seems very popular in the social sciences. I noticed that there is a recommended citation for each dataset. For example, [1] is has this one: "Targeted Input Programme (TIP) 2000-01", ​http://hdl.handle.net/1902.1/SSC-MWI-TIP2000-01-M1 V1 [Version]"

Implementation

Add a small box at bottom of dataset / resource page (or in sidebar on dataset page) with title "Cite this" with contents like:

%title. %author. Retrieved %date. %site_title.

For resource: %title = %dataset_title. %resource_name.

Could also add export to ref managers (e.g. to bibtex) but that is for later.

We should create a public AMI with CKAN pre-installed and configured such that users can easily create their own EC2 machine with a running CKAN to play with.

There are three phases:

1. [nils] Deploy an empty EC2 instance to become the CKAN image master instance
2. Install a CKAN and give it a standard configuration.
3. [nils] Create a AMI from the CKAN image master instance and publish it.

I am happy to do first and last. Who is installing and configuring CKAN?

Unfortunately AMIs are specific to region, architecture and storage type. We cannot maintain too many images, so a number of choices have to be made:

• Which distribution/version? Ubuntu 10.04 LTS
• Which architecture/instance-type? I suggest 64-bit/t1.micro
• Which region? I suggest us-east-1 and maybe eu-west-1
• Which storage type? EBS (way easier to make an AMI from than instance-store)
• Install CKAN from deb packages via mercurial/virtualenv? I assume the latter because the AMI is targeted to developers?

Currently, each ckan site needs its own ckan wsgi process. That eats a lot of resources where many ckan sites are served from one machine (e.g. eu3).

That would dramatically change if a ckan process could behave like multiple ckans (e.g. like Apache's "<VirtualHost?>", or tracd). Depending on the "Host:" header in the HTTP1.1 request, it would choose which local ckan ini file to obey.

I see two ways to constitute the map hostname-to-ini-file map:

• ckan reads a set of ini files, and each ini file declares which servers names it is responsible for
• In a global ini file, there are directives mapping servernames to ini files.

In either case there should be a global ckan ini having the default settings for all local ckan sites. Each site ini could be very short then, just having e.g. title, name, database credentials, active plugins etc.

Storage is now working but there are

• Integrate with Resources (e.g. create a resource for each file upload and give option to associate with a package)
  • Should we introduce rule that files *not* associated with a Resource are periodically deleted?
• Allow setting of a file name/path before upload
• Allow for file overwriting/deleting etc (how should this work -- do we want to allow this sort of thing)
• Integrate local file upload stuff in api/auth/*

Different Backend Issues

Local file store is rather different from 'remote' storage in various ways:

• For remote you don't want to use many buckets as there are bucket limits while for local you want to. Should we there have a single path that users provide which we then partition differently for different backends.

We need to offer a strongly simplified version, read-only of CKAN under publicdata.eu, with a focus on its role as search engine instead of a data catalogue.

This ticket relates to work on the PDEU theme only!

RDFa can be used as a simple way to expose linked data or at least sameAs the API version of the data but we need to make sure we do not expose anything different from the "official" representation.

Change the visual style of CKAN to be more like these sites:

• GitHub?
• Quora
• Google Projects

This does not include major UX work.
