WWW 2012 Metadata Challenge

The metadata committee is organising this year a challenge for 
developers in order to show case the utility of the conference metadata. 
Since 2007, the WWW conference is providing its metadata about papers, 
authors, programme, location, committees in RDF. The datasets are made 
available at the Semantic Web Dog Food web portal, which offers various 
access means to Linked Data applications. While the mere publication of 
such data is useful to contribute to the Web of Data, this year we will 
provide more diverse ways of browsing the data by encouraging data 
hackers to develop applications that leverage the conference metadata. 
To spice this up a little bit, we challenge developers to make the most 
interesting, most original tool and we will reward the best one with a 
prize. The submitted software must be made available as Web applications 
that the attendees can try on their laptop or their mobile phones.

1. Challenge criteria

The selection of the metadata tools is made according to minimal 
criteria. All applications that match these criteria will be made 
available for the attendees to try, no matter how many and how good they 
are. However, only few of them will be selected as "“featured 
application”s" before the conference, and one will be selected as best 
metadata application and the developers will be rewarded with a prize.

In addition to the minimal requirements, we provide additional desirable 
features that submissions should exhibit.

  Minimal requirements

    * The application should be an end-user application, that is, an 
application that general Web users can interact with or, even better, 
that WWW Conference attendees can play with during the conference.
    * The application must use the data provided by the WWW Conference 
and exploit as much of it as possible.
    * The application must be either a Web application, accessible and 
usable via a Web browser, or a smart phone application. There should not 
be any configuration files to modify and no extra library to install.

  Additional Desirable Features

In addition to the above minimal requirements, we note other desirable 
features that will be used as criteria to evaluate submissions.

    * The application provides an attractive and functional interface 
(for human users).
    * The application may use additional information sources that:
        - can be under diverse ownership or control;
        - should have some connection with the conference metadata (for 
instance, a dataset about points of interest in Lyon);
        - may be in different formats other than RDF.
    * The application should provide features that are useful to 
conference attendees.
    * Functionality is different from or goes beyond pure information 
    * The application is useful beyond WWW 2012 and may be used with 
other types of data (not necessarily conference data).
    * Multimedia documents are used in some way.
    * There is a use of dynamic data (e.g., workflows, GPS location), in 
combination with static information.
    * There is support for multiple languages and accessibility on a 
range of devices.
    * The application is usable by and adapted for mobile devices.

2. Important dates

Submission deadline:
     February 25th, 2011
Selection of featured applications:
     15th April, 2011
WWW Conference (attendees can test the applications):
     April 16th-20th, 2011

3. How to Participate

In order to participate, applicants must send by email the following 
information before 25th February, 2012 to

The following information must be provided:

    * Name of the application.
    * Abstract: no more than 200 words.
    * URL of a description: a hyperlink pointing to a description of the 
application that should show details of the system, including which 
features or functions the system provides. This should be no more than 2 
pages when printed, but it can link to other web pages giving technical 
    * Web access: the application should be accessible via the Web. If 
the application is not publicly accessible, passwords should be 
provided. A (short) set of instructions on how to start and use the 
application should also be provided on the web page.

Moreover, applicants may declare their intent to participate by sending 
an email to the organisers. This way, they will be notified when the 
dataset is available and they will get a link to a dump of the dataset.

4. Datasets

The datasets will be made available after the notification of 
acceptance. Before they are released, developers can start testing their 
application on previous conference datasets, such as WWW 2011 or ISWC 
2011, available at The Semantic Web Dog Food server. The datasets for 
WWW 2012 will be available there as well using the same format and 
vocabularies. Participants who sent an email prior to their submission 
will be notified when the dataset is available.

5. Winners and prizes

The best application will be chosen by the committee during the 
conference based on the experience of using the applications in the 
course of the event. The winners will be rewarded a monetary prize (to 
be decided). A short listing of "featured applications" will be defined 
before the conference.
