Raw

/raw or /download (latter may be better)

/dataset/{id}/resource/{resource-id}/raw

=> redirects to resource url (download)

API

/dataset/{id}/resource/{resource-id}/api[/....]

=> either redirects or directly serves /api/data/{resource-id}

Viewer (Explorer?)

Do data viewer but without anything else showing (full-screen?). this would not be just the data explorer but other cases too (including iframe etc ...)

/dataset/{id}/resource/{resource-id}/viewer

Resource (pre)-viewer without anything else (perhaps include resource title)

Assigning for kindly for review.

These would take about 20m to implement and would be *very* convenient from my experience of using the data API.

[x] Redeploy Sparql endpoint

Done at linkeddata.openlinksw.com/sparql

[x] Make sure it is available at datahub.io/sparql or semantic.datahub.io/sparql

[x] Generate daily dumps

[x] Make dumps available via web

[x] Notify Hugh once running

[x] Announce to LD guys

[x] Think about how we can apply this to publicdata.eu (can we do the same?) ... (being done elsewhere)

Need to investigate alternative payment gateways

1.7 will hide the link on the footer and put a deprecation notice on the related pages, but they should be completely removed on 1.8.

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.

Make sure the related item count is available on all dataset pages (inc. follow) when it is enabled.

CKAN returns HTML when an Accept header should make it return RDF/XML:

Take revelvant parts of autoneg ( ​https://github.com/wwaites/autoneg.git ) so that we can remove the dependency (just for two functions) and thereby remove flup as well.

Original bug report:

Hi CKAN devs,

Can I request that ckan.logic.get_action raises an exception if the action requested doesn't exist?

Two of us had a frustrating time tracking down an exception this morning. It's difficult when the exception is raised in python in a template because you don't get a line number. The problem was caused by a new logic function being added to another extension, and we hadn't updated the code there. So if get_action raised an proper exception rather than silently returning None then I think we'd have found the problem quicker.

I'd write the code for this, but as I understand that the new system would require a ticket, branch, pull request, code review, merge. It seems a lot to do for such a small thing.

Dave

The related tab on the dataset page doesn't change its appearance when selected like the other tabs do

Requirements

We need to clone the demo ODS site for DataGM as soon as we have a mostly working demo so that the DataGM team can try it out and comment/feedback on functionality.

Interface

None

User Stories

None

Tasks

[ ] Deploy demo DataGM site.

Estimates

When given a url parameter for a file it cannot fetch, the app raises a 500 instead of something useful.

Better error reporting in the JSON would be useful

From DR at DGU

Basically get_groups() appears to cache its results, but this falls down when subsequent calls are in a different session. We get this when saving a dataset. get_groups() first gets called in the controller when it is trying to work out what permissions the user has. It later gets called, and by this time c.userobj is detached, so get_groups() fails.

I'm working around this by refreshing c.userobj (from c.user) before calling get_groups(), but I wonder if the get_groups caching could detect the detached session and bypass the cache in this case?

diff at ​https://gist.github.com/3003117

Enable the organizations and organizations_dataset plugins, login to ckan, create a group, create a dataset and add it to the group. Edit the dataset, add some tags to it. The new tags are not saved when you submit.

Disable the organizations and organizations_dataset plugins and tag editing works again.

When a resource doesn't have a description, it is rendered as markdown from the description of the dataset.

If the resource does have a description it isn't rendered as markdown ..

See ​http://thedatahub.org/dataset/wikipedia-e3-timestamp-position-modification/resource/d883ab44-07f4-4992-800a-3e4bf5d53a96

I believe it should only return active ones. On DGU we see deleted publishers popping up.

Many users of CKAN want to have their own instance without much effort. Setting these up in separate places is a maintenance nightmare, we should much rather have some tenant separation in core CKAN. Some ideas:

• introduce model.Site and c.site
  • site has: custom CSS, extra_template_path, title, languages list, package_form, group_form (all configured via web UI)
• Subdomain detector to activate sites.
• use site in Authorizer instead of System, have a NullSite? for global things
• allow cross-site search
• packages are in a list of sites, m:n rather than 1:n
  • list of sites is string-based, can contain sites not in site table to express harvested external material which is not editable locally.

I'd like us to display a one-off banner that prompts users who log into thedatahub.org to go and update & their profile & fill in their email address (if we could do it just for those who don't have an email address, then even better) That is, once they log in, they see a banner which says: Please update your profile [here] and add your email address, so you can receive notifications, be able to reset your password and get updates

Then when we build notifications or if we decide to survey people, we can actually contact them. Email address should be required as standard

DR: Also, mention their Full Name too - v. useful for selecting correct user in group curation

Nils flagged up that Ubuntu launches another LTS in April which we should probably move to. This ticket is to get the ball rolling with what we do. We can always include in our package the exact package versions of deps that we want, but it is good to be in line with the release if possible.

Here's how to see the packages included with it: ​http://packages.ubuntu.com/search?keywords=python-pylons&searchon=names&suite=all&section=all

Pylons 0.9.7 -> 1.0-2 Requires a small amount of work SQLAlchemy 0.7.3-2 OK Babel 0.9.6-1 OK Genshi 0.6-2 Perfect

Another alternative is to move to another web framework, especially minding that Pylons is not being further developed.

Sean spotted that some strings need internationalising, such as flash messages. Generally all strings that appear on the web front-end should be internationalised.

Particular places that need i18n:

• ckan/controllers/admin
• ckan/lib/base

Note: there are some exceptions, such as in i18n.py, very obscure error messages and stuff that only appears on the API.

NB: there is a cost in making a string internationalisable (all our volunteers have to translate it), so we should not be too zealous. We should also look at the i18n/ckan.pot to see if any of the existing strings can be reused.

We want to add "activity streams" (chronological lists of activities) to CKAN.

Activity streams standard: ​http://activitystrea.ms/

Super branch where the feature was initially developed (this has now been merged into master): ​https://github.com/okfn/ckan/tree/feature-1515-activity-streams

Etherpad: ​http://ckan.okfnpad.org/notifications (most relevant parts inlined here)

Friedrich's mockup: ​http://datahub.pudo.org/pudo

Tasks

Strikethrough means the task is done.

• New domain objects Activity and ActivityStream? [2d] #1298

• Migrate existing data into activity streams model [3.5d] #1510

• Generate activities when objects are saved [4d] #1298

• Get the activity stream for a given user as a JSONifiable list of dictionaries [1d] #1511

• API call for getting a user's public activity stream as JSON [0.5d] #1495

• API call for getting a user's public activity stream as rendered text, HTML, etc. [5d] #1494

• Render a user's activity stream on her user page [3d] #1496 (needs review/page design work)

• Generate activities for other types of objects besides users (e.g. packages, groups, tags, extras, and save them in the database.

• Logic functions for getting activity streams for packages, groups, and users.

• API calls for getting activity streams of packages, groups, and users as JSON.

• Rendering activity streams for packages and groups etc. into their pages. (done but disabled pending page design work)

• API calls for inserting events into activity streams. (Still need to handle activity details in the API, ticketed).

• Conform to activitystrea.ms standard

• Enable users to subscribe to and unsubscribe from activity streams, see an aggregated activity stream on their dashboard page.

• Generate aggregated activity streams for arbitrary sets of multiple activity sources/streams

• Email notifications

• Extension point for extensions to register themselves as renderers for different types of activity

• Deploy to UAT [0.5d]

• Docs and announce [1d]

This requires adding a logic function for emitting an activity stream event, and then editing the logic functions for creating or updating users and making them call the new emit event function. This same emit event function can later be used to emit activity stream events for other types of object as well.

Add logic functions for getting the activity stream for a group in JSON and rendered HTML formats, add HTML activity stream into group page.

This is a fairly big feature to add. Analysis: ​http://ckan.okfnpad.org/27

This ticket is related to #1635 (email notifications for activity streams) which is about managing a list of activity streams for which the user receives email notifications. There are decisions to be made about how the two will work together.

Dump and load JSON explicitly instead.

The create_activity() logic function already exists, but validation and authorization need to be added before it's hooked up to an API call.

How big is it? How are we going to store it? etc.

Currently rendering of activity stream events to HTML works by looking up a rendering function in a dictionary that maps activity types ('new package', 'changed group', etc.) to rendering functions that take an activity stream event and return the rendered HTML.

There needs to be an extension point where extensions can register their own rendering functions for particular activity types.

The activity streams feature is already thoroughly tested via the logic layer and API calls, but there needs to be a quick test of the rendering code, e.g. fetch a user's page (thus testing that ckan doesn't crash while rendering it) and then assert that the expected activity streams HTML is in the fetched HTML.

Add Vocabulary domain class, add logic functions for creating, updating, listing, getting, deleting vocabularies, add tests.

See the etherpad for notes: ​http://ckan.okfnpad.org/22

ckan/logic/action/get.py:tag_list() Currently (I think) just returns all tags in the CKAN instance that the user has access to. Needs an optional argument to get only tags from a particular vocabulary? When called with no argument, should only return free tags? Also add an optional dataset argument, so you can get tags for a given dataset and/or vocabulary?

ckan/logic/action/get.py:tag_autocomplete() Add optional argument to get only tags for a given vocab? When called with no argument, should get only free tags?

ckan/logic/action/get.py:tag_search() Again, optional arguments for restricting by vocabulary and/or dataset.

At the very least we should make our JSON output conform to their spec:

​http://activitystrea.ms/

Add a vocabulary column to the tags database table, change tags to have unique (tag_name, vocabulary_id) instrad of unique tag name, update methods in the Tag and Package classes to deal with the fact that tags may belong to vocabularies and that tag names are no longer unique.

Add API calls for adding one or more tags to and removing one or more tags from a vocabulary, without affecting the other tags in that vocabulary and without having to pass the full list of the vocabulary's tags.

The HTML templates for some activity stream activities link to objects (packages, resources, etc.) by their names, e.g. /dataset/foo, but if the object has since been renamed then the link will be broken.

Possible solutions are to use the object ID to find its current name at rendering time and link to that, or link to the object by ID rather than by name.

Linking by ID is both simpler to implement and better. Links by ID are ugly, but they are permanent and don't break when an object is renamed. We should be using links by ID everywhere on CKAN, so that when third-party sites copy-paste our URLs and link to us, their links don't break later.

Fixing this means fixing the dataset_link(), resource_link(), group_link() etc. functions in ckan/lib/helpers.py which will change the links everywhere in CKAN where those functions are used to link to objects (which should be everywhere where we link to an object).

If we want to have nice looking by-name URLs and what them to be permanent, then we need to change CKAN so that objects cannot be renamed.

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)

Done on branch feature-1698-tag-taxonomies

Currently tag_show() only works with free tags, it's not possible to get a tag_show for a vocabulary tag.

All strings from the ckanext-ecportal extension (and from CKAN core) need to be exported to a pot file to send to tenforce.

User names and descriptions are not translated.

...but only if it can be done reasonably quickly.
