CKAN: Ticket Query

#1158: Put PDEU into read-only mode and remove unneeded functions

pudo — Wed, 25 May 2011 15:36:26 GMT

PDEU should be in a mode where:

Users cannot edit or create packages
Users cannot sign up on their own
AuthorizationGroups? and RevisionHistory? is completely gone from the UI
Groups have been repurposed as Subjects

#1157: A simple theme for publicdata.eu, CKAN

pudo — Wed, 25 May 2011 15:32:53 GMT

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

GitHub?
Quora
Google Projects

This does not include major UX work.

#1155: Harvester for data.london.gov.uk

pudo — Wed, 25 May 2011 15:28:38 GMT

Write a harvester for data.london.gov.uk to import catalogue metadata into PDEU. API (or at least documentation) is available at: http://sourceforge.net/projects/londondatastore/files/

#1156: Scraping harvesters for Paris and Vienna Catalogues

pudo — Wed, 25 May 2011 15:30:28 GMT

Import metadata from both sources into PDEU via the Harvesting framework but by scraping their respective catalogue pages.

#1162: Define a common extra for storing the geographic extent

amercader — Thu, 26 May 2011 11:18:24 GMT

We need a common extra across the different harvested sources that defines the extent of the data. We will have mainly national level catalogues, but also at a lower level (region, city).

Relevant discussion: http://lists.okfn.org/pipermail/ckan-discuss/2011-May/001245.html

#1173: Offer a DCat representation for packages in the API

amercader — Wed, 01 Jun 2011 14:47:19 GMT

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

#1159: Add RDFa to CKAN package pages

pudo — Wed, 25 May 2011 15:38:27 GMT

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.

#1164: Cloropleth Map of European Data Availability for PDEU

amercader — Thu, 26 May 2011 11:20:24 GMT

A nice map in the homepage showing the availability of data across Europe

#1160: Havest CSW servers on PDEU

amercader — Thu, 26 May 2011 10:54:31 GMT

It could be interesting for the publicdata.eu project to add some CSW datasources. Thanks to the INSPIRE directive, there are quite a few national catalogs of geodata that could be worth harvesting. Work on this should include:

Compose Endpoint List (1d)
Harvest on staging system and evaluate which sources have useful material (2d)

First point is being performed in this GDoc: https://spreadsheets.google.com/spreadsheet/ccc?key=0Atp3cZFjuIOAdDBVQWRINnlfN1d0b2lleHVEdjBSb2c&authkey=CNu4hsEB&hl=en_US#gid=0

#1174: API Representation Registry

pudo — Thu, 02 Jun 2011 21:43:12 GMT

As CKAN grows, more and more optional representations of packages will become used. Besides RDF (which is the motivation for this ticket), support for DSPL, home-grown XML, or CSV listings is imaginable.

To properly support this CKAN should have an extensible representation registry that can be extended when new output types become available (and without changing the API in the process). This needs to integrate in two places:

We need to add support for file format extensions to the package handler and REST API.
We need to add HTTP content type negotiation (Accept headers).

To support this we should have a registry with two registers:

to map format extensions to mime types (e.g. "json" -> "application/json")
to map mime types and entity types to converter functions (e.g. 8"application/json", ckan.model.Package) -> func(obj, mime_type) )

This should be set up on load_environment so that IConfigurer plugins can feed into it.

The registry should then first be added to _finish in the REST API (which needs to be refactored to be passed the {format} part of the URL if one is given. Based on the format part and HTTP headers, an appropriate representation can be generated by the registry and then be returned to the user.

Forwarding of requests to the regular WUI controllers with Accept headers set or a format specified can be implemented in a separate effort.

#1161: Build a simplified theme for PDEU

amercader — Thu, 26 May 2011 11:03:55 GMT

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!

#985: Harvest other data catalogues

pudo — Mon, 14 Feb 2011 10:36:39 GMT

data.london.gov.uk (1d, ping DERI)
catalogues from Paris and Vienna (1d)

Others?

digitaliser.dk (1d)
data-publica.com (2d)
data.suomi.fi (2d)
dati.piedmonte.it (1d)
portalu.de (2d)
