Package search results page package/search

• need clearer delineation between search entry form and results.
• 0 results needs to be clearer, and the alternative suggestion: 'would you like to create a new package' needs to not look like a search result.
• "N tags found" -- why do I care? this should be presented as "filter results by tag" -- very unlikely that I'm looking for a tag: I'm looking for a package, but tags might help me narrow down my search.
• tags should be displayed more like the way they're displayed when you add them to a package (i.e. blue 'tag' background)
• filter out particular tags
• tag cloud?
• copywriting: "Packages - Search" -> "Search packages"

• Propose three-column package listing: two lists of highest-scorers on some metric and last column is an invitation to register a new package, with a little copy explaining what's involved and why you'd want to.
• Add in search widget

Package edit page package/edit/mypackagename

• Ability to add the package to groups on this page.
• Fields could be grouped.
• Inconsistent capitalisation (Url -> URL).
• Tag editor YUI script appears to break occasionally.
• Perhaps move to two column forms to save vertical space?
• Notes field to monospace?
• Extras fields need some jQuery love -- shouldn't have a fixed number available.
• Typography is a bit of a mess.

Tags landing page tag

• Both search for tags *and* browse the list of tags right here
• Big cloud of tags (sorted by popularity/usage?) filterable with a search box.
• Tags search page tag/search and list tag/list are both redundant and should be merged straight into tag.

Not so keen on URLS such as /package/edit/mypackagename. These seem to be task-oriented rather than resource oriented (which would be /package/mypackagename/edit), and unstable: there is a common root for /package/edit/mypackage and /package/history/mypackage which is not reflected in the URL structure.

• There is huge inconsistency in the titles of pages across the site: to give one example "Edit Package:" vs "Package: mypkg [not linked]" vs "History - mypkg [linked to package page]"
  • Normalize and use terminology: "Data Package" - also change in navbar (but nowhere else for the time being). So hvae Data Package - mypkg, Data Package - mypkg - Edit etc
• pagination is currently lost in amongst the results list. needs to be *much* more obvious, and should appear top and bottom, or at the very least at the bottom!

• 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.

Integrate new test upgrade into testmigrate stuff.

New "migrate.ini" config file programmed with the db to be used for migrate tests and a param saying where the db dump is.

​http://ckan.net/group/publicdomain has:

"There is 16 package in this group. There are 16 packages in this group."

Search of package name and title (and other fields) using regular expressions.

Current example use-case: Wanting to specify packages with title beginning with 'B'.

Issues:

• Syntax for specifying regex over natural language search - could it be contained in the q param so be available to users of the WUI, or do we simply make it alternative fields?

Implementation:

• Postgres reg ex searching detailed here:

Overview

Functionality to formally associate packages. We see a need for specific parent-child, inheriting or dependency relations. Not only should this help navigation between packages in the web interface, but it also provides a mechanism to automatically pull dependencies when downloading a data package, in a similar manner as we see in software package management.

Examples

1. There are 27 packages in data.gov.uk to do with the Data4NR's Health Poverty Index. There is currently no common link between these, unless you search for 'HPI' (which also brings up House Price Index), or look under tag 'health' (which also has 600 other results). There should be a link on each HPI package page to navigate to the other 'sibling' HPI packages, and to a 'root' package that has info about the set. This could be partially achieved using the existing tag or group concepts, but a more explicit/official/obvious marking of their relationship could be beneficial.

2. In ckan.net is freedict, a collection of translation dictionaries. You could make each dictionary a child package and use this system. But it would probably be better to make each dictionary a different resource in the same package. (There are other ideas to denote a resource as the data making up a 'portion' of package, or a 'whole' of the package, to help people downloading datasets in the software package style.)

3. OSM has had some Naptan data imported (bus stops), with special permission - i.e. a more liberal license. It would be useful to show this link on both OSM and Naptan packages in CKAN: OSM 'derives from' Naptan with a comment about the license change. I'm not sure this is useful to an automatic download or use of these datasets, but may aid exploration on the CKAN website and understanding the provenance of the bus stop data on it.

4. IPCC collection of data linked / mirrored. Not sure if there are useful relationships here?

5. Dracos gets postbox locations from crowd sourcing and OSM. We could say Dracos 'derives from' OSM.

See more examples discussed here: ​http://trac.ckan.org/ticket/253

Implementation

This is split into four tickets:

• Model: ticket:254
• Read in WUI: ticket:255
• Edit in WUI: ticket:256
• API: ticket:257

No need for write access to be provided API for the moment.

This ticket also encompasses ticket:169 (Package derivations) and ticket:176 (Package dependencies).

WUI:

• View: show both sides of the relationship (but think carefully -- e.g. a given package may have *many* dependents ...)

API:

• Appear in package listing Example: 'relationships': [{'is_dependency_of':'osm', comments:'Since version 0.2'}, {'is_parent_of':'bobs_maps'}]

Pressing the 'make an enquiry' link on the package read page gives 404. (Also links should also be changed from isitopen.ckan.net to isitopendata.org)

Example link is:

​http://isitopen.ckan.net/enquiry/create/?ckan_package=zeno

which gets forwarded to:

​http://www.isitopendata.org/enquiry/create/?ckan_package=zeno

which gives 404

As a user I want to track changes to a particular package.

Provide an Atom feed, linked from the package read page.

If the notes field could use a WYSIWYG editor with word cleanup this would really help users who may well be pasting in text from Word (and I guess may have been approved or written by someone else)

having auto-complete on tags would both make the system easier to use - and reduce the risk of synonymous tags being created inadvertently.

Does the department drop down options list interact with user permissions - so that users who only have rights to one department only see that option ?

Similarly for licenses - can this reduce to the set of allowed options for this user/

What level of validation is there on the fields?

If the key to an extra field has a space in it then various form code doesn't work. Either need to disallow spaces or cope with them.

When I edit a package on no.ckan.net with lots of extra fields, lots of them completely disappear.

Metastable branch.

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).

Use Nick's examples as a basis to revamp the formalchemy usage, principally in the package edit form.

• ​http://static.whiteink.com/css/examples/forms.html
• ​http://whiteink.com/temp/ckan-forms/

These don't work.

doc/api.rst needs to cover the new Revision REST interface.

When you edit a package, all of its resources are deleted and a fresh set created. This causes all history of them to be lost.

Currently the package form gives you 3 fields for extras. To get more you have to hit preview. This is obscure. It would be better to have some buttons to add/remove fields, just like with the resources.

Failing test: ckan.tests.models.test_resource.TestResourceLifecycle?.test_03_reorder_resources

Not clear how visible this is to the user.

Related to ticket:292

Currently a package's history page (/package/history/xyz) and related feed only shows changes to the core package i.e. ones which create a PackageResource?. This doesn't include changes to tags, extras and resources. These need to be added.

There is the complication that the 'diff' function doesn't currently work beyond PackageResource?. Unless this is quick and simple to fix, I suggest we let the diff remain slightly broken for now.

Rufus suggests alongside the existing methods:

pkg.all_revisions()
pkg.diff()

we have ones which also include the related objects (tags, extras, resources):

pkg.all_revisions_full()
pkg.diff_full()

You could have a function which returned these related objects. Ideas:

revobjlist = [ self, resources, extras ]
list of tuples: (revobj, changed_revobjs)
list of tuples: (revobj, {objtype: [changed_revobjs]})
tuple: (rev1, {Package: [ object_id, object_id], PackageTag: [object_id, object_id2] ...}

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.

If you search for unescaped characters such as '`' (backtick) in the URL in Chrome then you get a 500 error.

e.g. ​http://www.ckan.net/package/search?q=fjdkf2B%C2%B4gfhgfkgf{gpk fjdkf2B´gfhgfkgf{gpk

returns this exception:

Use cases

• Register for package changes
• Register for all revisions
• Notified of a package change
• Notified of a revision
• Deregistration
• Configuration of port in pylons config

Design

• Default port: 5672 (standard for AMQP)
• Exchange name: 'ckan'
• Exchange type: topic exchange (most flexible)
• Routing keys: (see below)

Routing detail

Routing key format: "OBJ_TYPE" (NB tags should be identified by their name, not ID)

Example routing keys

• 'package' - Package edited/created
• 'resource' - Resource edited/created
• 'revision' - Any change
• 'db.clean'
• 'db.rebuild'

Example queue bindings that clients may use:

• * - no filtering - client receives all notifications
• package - only changes to packages
• revision - all revisions
• db - all database operations

Versioning

Since message payloads will be tied into the REST Entities, it makes sense to join up with the REST versioning. This could be achieved by providing new exchanges called 'ckan-1.1' perhaps?

• simple example of an external client?

Currently search indexing is triggered directly using a Postgresql db callback. Now take advantage of the Notification system to register interest in all package changes and db changes to trigger this instead.

The indexing shall run in a separate shell/process, managed by supervisord.

Later versions of python use json which is better than simplejson, but it must be kept as an option for compatibility. So centralise the import of json to ckan.lib.helpers.

The python time module is supposed to recognise timezones such as 'UTC', 'GMT' and 'BST' using the %Z parameter. This works fine on British installs, but the buildbot (for example) gives this error:

DateConvertError?: Could not read date as ISO format "%a, %d %b %Y %H:%M:%S %Z". Date provided: "Mon, 04 Jan 2010 09:30:00 BST"

It turns out that it only recognises local names of timezones.

The ONS import doesn't care much about timezone, so we should just ignore it, avoiding these problems.

This is a problem with the package page e.g. ​http://ckan.net/package/open-election-data-project . The feed icon links to [1] and the text next to it "Subscribe" links to [2]. Surely these should be the same? The second link seems to right one to me.

• [1] ​http://ckan.net/package/open-election-data-project?format=atom
• [2] ​http://ckan.net/package/history/open-election-data-project?format=atom&days=7

An install of CKAN should be configurable without changing any of the installed files. This makes it clear to upgrade CKAN. Complete the changes in this wiki page to allow static files to be served from outside CKAN paths over CKAN versions and additional CSS file to be pulled in.

As a

CKAN client using JQuery

I want to

call the CKAN API and instead of receiving back JSON I get JSONP. i.e. "%s(%s)" % (callback, json_content)

Suggested implementation

All API calls allow the JSONP 'callback' parameter to be specified in the request and this wraps the JSON response. See suggested patch to rest.py by Donovan Hide:

​http://knowledgeforge.net/ckan/trac/attachment/ticket/336/resource.patch

Test

import re import unittest

def test_jsonp_callback():

response = self.app.get('/api/search/resource/?url=​http://www.scraperwiki.com&callback=jsoncallback') match = re.match('jsoncallback\(.*\);',response) self.assertTrue(match)

response = self.app.get('/api/search/resource/?url=​http://www.scraperwiki.com') match = re.match('jsoncallback\(.*\);',response) self.assertFalse(match)

I think the point needs to be made that JSONP only works for GET requests and not POST/PUT/DELETE, so there needs to be a check for that in the _finish_ok method.

(thanks to Donovan Hide for test)

PUT to /rest/api/package of {"name": "name", "resources": ["someurl.com/data"] } (i.e. resource is a string, not a dictionary) gives 500 error, when it should give a 400 error and helpful error message.

As a

SOLR instance

I want to

keep my search index of CKAN packages up-to-date

Implementation

• Using asynchronous event notifications
• Running in a separate process to CKAN

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.

On ckan.net there are plenty of packages (and indeed their tags) with the word 'statistic' in them, but no packages turn up when you search for it:

​http://ckan.net/package/search?q=statistic&search=Search+Packages+%C2%BB

(Using Postgres full text search)

You get redirected for a number of different reasons - often confuses me let alone the average user!

Cost: 1h

As a

user browsing a CKAN package which has a resource in a bad format

I want to

be alerted to the possibility of scraping it on scraperwiki

Implementation

This should be done in a CKAN extension. It should appear in a side-bar on the package read page.

If the package does not have a resource with scraperwiki.com in the url, then it displays this message:

Title: Scrape it
Image: (Scraperwiki dumper truck)
Body text: Could this data be in a better format? Why not use Scraperwiki to extract data from tables, Excel or PDF for everyone's benefit? You can ​request this data is scraped or even ​write the scraper yourself.

• examples of posting a new package
• example license_id - explain
