Re: The Linked Data-a-thon starts NOW!

Hi there.
Fun times!

If I had noticed earlier I would have got this addressed at source, but I have a feeling that quite a few people might be already starting on the work - sorry I didn't notice earlier.
And the admin@data.semanticweb.org email address bounced, and I am not sure who actually runs it.
I am guessing that many entrants will use the mandatory data, plus other data from semanticweb.org, and this may need a bit of a health warning.

If you are getting data from the dumps (I have done nothing to check the other sources).
Some problems in the dumps that you probably want to sort out before you start using the data:

http://data.semanticweb.org/dumps/other/pref_labels.rdf
is not valid RDF.
The last three entries should close with </rdf:Description>, not </Organization>

www-2008-complete.rdf:        <rdfs:label></rdfs:label>
fis-2010-complete.rdf:        <rdfs:label> </rdfs:label>
aren't very nice (rather empty).
One comes from
    <Person rdf:about="http://data.semanticweb.org/person/">
        <swc:holdsRole rdf:resource="http://data.semanticweb.org/conference/fis/2010/chair"/>
        <rdfs:label> </rdfs:label>
        <name> </name>
which is suspect.
And I am not sure that
LDOW-2008-complete.rdf:   <rdfs:label><![CDATA[Linked Data Spaces & Data Portability]]></rdfs:label>
is what you really want.

Then I got into real problems doing coref on the data:
hg@cohen [2011-10-02T14:56:26] > grep "<name> </name>" models/*
models/eswc-2007-complete.rdf:        <name> </name>
models/eswc-2007-complete.rdf:        <name> </name>
models/eswc-2007-complete.rdf:        <name> </name>
models/eswc-2007-complete.rdf:        <name> </name>
models/eswc-2007-complete.rdf:        <name> </name>
models/eswc-2007-complete.rdf:        <name> </name>
models/eswc-2007-complete.rdf:        <name> </name>
models/eswc-2007-complete.rdf:        <name> </name>
models/eswc-2007-complete.rdf:        <name> </name>
models/eswc-2007-complete.rdf:        <name> </name>
models/eswc-2007-complete.rdf:        <name> </name>
models/eswc-2007-complete.rdf:        <name> </name>
models/eswc-2007-complete.rdf:        <name> </name>
models/eswc-2007-complete.rdf:        <name> </name>
models/fis-2010-complete.rdf:        <name> </name>

http://data.semanticweb.org/conference/ICPW/2009/paper/main/8
is in the icpw-2009-complete.rdf RDF, but 404s (both RDF & html)
In fact a lot of icpw-2009-complete.rdf URIs 404.

There are other things to do with diversity of ontology (dc:title used for both terms and vanilla, I think), but they are all part of the rich tapestry of consuming RDF.

I think I'll stop for now - hope that helps.
Cheers

The spirit of this competition is to demonstrate the world what can be done with Linked Data, that could not be done before the Linked Data era, even in a short amount of time. The competition starts today, October 1, 2011, and it closes 14 days later, on October 15, 2011 (midnight hawaii time). During this time each participating team works locally or remotely to develop a Linked Data based application that satisfies the following requirements:

Everybody who participates will have a 5 min slot (depending on the number of submissions) to present the application. If a participant is not attending ISWC, they can upload a video or screencast and this will be showcases to the audience. We also ask that participants publish a report on the web about the application.

It will consist of two parts: First, attendees at the Linked Data gathering will have a chance to listen to the presentations and vote for their favorite application, resulting in a ranking of the submissions. In addition to this ranking, a panel of judges will choose their winners. The final decision will be determined based on an equally weighted average of the panel voting and the attendees’ rankings.
