The Wallace Line

The second broken dbpedia application used to show the albums for a selected Rock artist or Group as an HTML table and a Simile Timeline.  This application was REALLY broken!

• the scripts had been moved on the server by the administrator in an attempt to solve a recurrent eXist failure
• the meaning of the category "Rock and Roll Hall of Fame inductees" changed so that some artists dropped of the list
• the dbpedia vocabularies changed - for instance releaseDate was http://dbpedia.org/property/released but is now http://dbpedia.org/ontology/releaseDate
• identification of which works are albums changed - a skos category was used but has been functionally replaced by an rdf:type of http://dbpedia.org/ontology/Album

But the killer for the application is that http://dbpedia.org/property/cover used to be  the full URI to the cover image in Wikipedia, but is now just the file name, eg. Pepper's.jpg  Since the image files have URIs like http://upload.wikimedia.org/wikipedia/en/6/67/Pepper%27s.jpg, it is not possible to reconstruct the image URI. 

The application is much the poorer with the lost of visual appeal of the album cover but it is working again
