We are glad to announce second release of the proDataMarket marketplace!
What is proDataMarket Marketplace?
The proDataMarket marketplace is a virtual space that connects providers of open and proprietary real-estate and related contextual data with consumers of this data. On one hand, the marketplace aims at making it easier for data providers to publish, distribute and eventually reach out to potential consumers of their data. On the other hand, it helps data consumers discover and easily access data published at the Marketplace.
Access to the marketplace can be done through the marketplace landing page available at http://prodatamarket.eu.
Conceptually, there are two areas in the marketplace: Consumer site (area dedicated to data consumers in the marketplace) and Producer site (area dedicated to data producers in the marketplace).
Services available to data consumers have been deployed at the Consumer
The data consumer services have seen further development since their initial release in the first period of the project. The Portal has been redesign following the feedback from the business case providers. New design includes landing page (see the screenshot above) with easy access to and search over the whole catalogue of data published in the marketplace.
Interactive geospatial data exploration
The Portal’s geospatial data analytics based on Amerigo Data Visualisation Service have been improved. Since its first release, map widgets have been transitioned from Leaflet to CartoDB, to support fast map rendering and provide a UI for maps configuration. New data exploration capabilities were added to the maps with data filtering widgets, that were developed on top of CartoDB. To accommodate different types of data of the business case providers, two types of filters have been implemented: discrete and continues.
Access to open and proprietary data
User profile management has been added to the Portal. Not-authorised users can browse through all open data available in the marketplace and samples of proprietary datasets, if their owners made them available for public. In order to get access to proprietary data, users have to sign up.
Purchase of proprietary data
Finally, authorised users can now buy proprietary data in the marketplace through the payment component, new feature of the Portal.
The purchase itself is implemented in the Purchase Management component that takes as input instructions about which data or data subsets are sold at which price. These instructions are passed to the component via a subscription configuration file. At the moment this file is prepared by the technical partners (SpazioDati, SINTEF and Ontotext) based on configuration options received from data producers (see data publisher instructions). In the future, data producers will be able to generate configuration file automatically using the Data Pricing Setup component.
Please, note, this feature is available for proprietary paid datasets only such as “Social Network Thermometer by Municipality”, as demonstrated in the screenshot below. Open data (e.g., “State-owned buildings by municipality”) is public and free, hence, no subscription options are shown.
Services available to data producers have been deployed at http://publish.prodatamarket.eu, the DataGraft portal. The latest release of the DataGraft portal has been announced in the recent blog post.
Current release of the marketplace includes a tutorial for data producers that describes the process of data publication from setting up a database to cleaning data and populating the database, to cataloging data and configuring it visualisation at the at the Consumer portal. The tutorial is available at https://store.prodatamarket.eu/publisher_help/.
Marketplace Platform overview
Technical platform of the marketplace is composed of the tools, services and infrastructure developed to support two types of users: producers and consumers. Diagram below gives an overview of the marketplace and services it provides for data producers and data consumers.
