-------- Forwarded Message -------- Subject: Re: Quick comments on DQV after F2F meeting. Date: Fri, 24 Apr 2015 07:53:11 +0200 From: Christophe Guéret <christophe.gueret@dans.knaw.nl> To: Riccardo Albertoni <albertoni@ge.imati.cnr.it> CC: Antoine Isaac <aisaac@few.vu.nl>, Christophe Gueret <christophe.gueret@dans.knaw.nl>, Deirdre Lee (Derilinx) <deirdre@derilinx.com>, Phil Archer <phila@w3.org>, Debattista, Jeremy <Jeremy.Debattista@iais-extern.fraunhofer.de> Hi Riccardo, Thanks for this great start! Here are a few suggestions for changes and discussions : * "dqv:refersToDcatDataset" could better be "dqv:refersToDataset" to let people feel free to also use the relation with their own "MyCAT" which would subclass DCAT. It's also shorter ;-) * I think the class inheritance arrows for dqv:CollectionOfMetricsResults and dqv:Standard should be inversed. Besides, I don't see why the collection of metrics has to be a qb:Dataset I did not look closely at how the diagram for DUV was made but we could look into using the same tool for both eventually...
