Jaroslav,

It is really necessary to assume a particular purpose for a Dataset? It seems to me that requiring a Dataset "to serve a particular, even hypothetical information need and any kind of digital processing and not simply the task of distribution (software)" creates a restriction that might render existing implementation non-conformant. For example, I know if work where Software Distributions are modelled as dcat:Distributions under a Software Solution modelled as a dcat:Dataset.

As to the CKAN definition of Dataset, I think that every CKAN Dataset is a dcat:Dataset but the inverse would not necessarily be true. 

Makx.

   Dear all,

     my initial assumption DCAT is about registries of (structured) bulk data was in deed challenged
   by the mentioned use cases, since they consider any type of digital artifact including service endpoints.
   As already discussed in context of ID6, Web Services are a sample of dynamic Distribution which exposes
   a particular representation of the rather abstract Dataset (~ Information resource), so I'd exclude
   them from the Dataset layer.
   
   I'd intuitively expect the content of a Dataset to serve a particular, even hypothetical information
   need and any kind of digital processing and not simply the task of distribution (software).

   Here the working definition of a "dataset" in CKAN seems relevant [1]:
  
    "For CKAN purposes, data is published in units called datasets. A dataset is a parcel of data -
    for example, it could be the crime statistics for a region, the spending figures for a government
    department, or temperature readings from various weather stations."

   In next telcon I'll try to summarize the issues, but we may ask Andrea to comment on his detailed UC ID20.

   Best regards
  Jaroslav
