segnalo la prima bozza di questo vocabolario che estende DCAT con informazioni destinate a rappresentare la qualità dei dati:

http://www.w3.org/TR/2015/WD-vocab-dqv-20150625/

interessante questo pasaggio:

"This vocabulary does not seek to determine what "quality" means. We believe that quality lies in the eye of the beholder; that there is no objective, ideal definition of it. Some datasets will be judged as low-quality resources by some data consumers, while they will perfectly fit others' needs. Accordingly, we attach a lot of importance to allowing many actors to assess the quality of datasets and publish their annotations, certificates and opinions about a dataset. A dataset's publisher should publish metadata that helps data consumers determine whether they can use the dataset to their benefit. However, publishers should not be the only ones to have a say on the quality of data published in an open environment like the Web. Certification agencies, data aggregators and data consumers can make relevant quality assessments too."

Se guardate ci sono estensioni per tracciare le provenance, e altri indicatori che sembrano disponibili per poter assegnare metriche numeriche di vario tipo. Secondo me si potrebbe usare come base anche per costruirci su delle consultazioni, una volta tanto superando i fogli excel: mi piace l'idea che si possano rappresentare risorse in modo indipendente e molteplice, così che chi poi dovrà consumarle possa decidere per così dire "di chi fidarsi".
