More precisely, aren't the notion of subdataset and the notion of slice somewhat aligned? pa [1] http://www.w3.org/2011/rdf-wg/wiki/TF-Graphs-UC#.28A_PRIORITY.29_Slicing_datasets_according_to_multiple_dimensions On 10/14/2011 04:06 AM, Jeremy Carroll wrote: > > TopQuadrant code routinely queries datasets that are provided by other > vendors; hence we have an interest in the dataset abstractions that are > provided in the standard. > > A particular area of interest for TopQuadrant is that we often want to > have a simple dataset algebra, where given a dataset with some set of > graph names N = { n1, n2, .... nk }, we may want to run a query against > a subdatset M of N, consisting of only some of the ni, e.g. M = { n3, n4 }. > Given such a capability then, at least over the powerset of N, we can > provide the usual set theoretic operators of union and intersection to > implement a change of application focus by considering a different > subdataset. > > I am wondering what is the best way to add this issue to the mix here.
