CKAN (Comprehensive Knowledge Archive Network) is an open-source data portal platform that provides an out of the box solution for managing, transferring, and accessing data. CKAN operates under a SaaS model and was created to help data publishers make their data open and available. The CKAN platform contains a catalog system with a web interface, data visualization and analytics, workflow support, access control, data storage, and federated structure.
The web service is broken down into two distinct parts: Search and Model. The Search API exposes methods for searching resources, datasets, and revisions, as well as tag counts. The Model API provides a variety of GET, POST, and PUT operations for manipulating, creating, and retrieving model resources from the platform.
The next generation of smart city applications and user interfaces are beginning to emerge based on the European-initiated FIWARE open API platform. The platform provides an open source toolkit of APIs and backend infrastructure components that enable app developers to create new city solutions.
A new API tool that transforms open datasets so they can be accessed by a REST API is capturing the attention of local governments interested in implementing smart cities policies. The DataTank is a data publishing platform that can also be used as a plug-in with the CKAN open data platform. It is created and managed by the Belgium chapter of the Open Knowledge Foundation, which operates as a social enterprise startup. ProgrammableWeb spoke with The DataTank's Technical Lead Jan Vansteenlandt about the new open data/API tool and how it can be used to drive the smart cities agenda.
In a presentation to the recent Open Knowledge Foundation conference in Switzerland, MapBox CEO Eric Gundersen argued that open data business models will be an ‘intermediary’s game’: a model that will position open APIs as the key tool in creating business value.
Exversion is hoping the need to access wide-ranging open datasets has matured enough to create a viable business as an open data marketplace. Their new Exversion API provides developers with a RESTful interface to search and access the open datasets stored on the Exversion data platform. At present, the API returns queries in JSON or XML format, with full XML support to be provided in the near future.
Open data infrastructure is being built out across the globe to better allow governments at all levels to improve access to data sources. Across the globe, governments are adopting their own API management platforms, announcing roadmaps for data accessibility, improving internal API capacities and unlocking government-held data so that it can be used by local citizens and businesses seeking to build new commercial products and technologies.
Of the many APIs we published this week, twelve were highlighted on the blog by our team of writers. In this post, we’ll shine a spotlight on those twelve, which included Google's many newly released APIs. Included in Googles recent releases are the Content Experiments, Cloud SQL API, CalDAV, and the CardDAV APIs. To give a background on each, the CalDAV API allows developers to manage their calendar, the CardDAV to manage contacts, the Content Experiments allowing for Google Analytics to be used for A/B testing, and finally the Cloud SQL API to perform certain tasks for MySQL database. To learn more about these APIs, visit the Google page as well as the Google API blog post.
An independent, open source platform aimed at making it easier for governments and businesses to publish open data has released a new version of their API. The CKAN API allows access to catalog listings of open datasets, full-text searches, and sharing of statistics on open data usage.
