             Summary: Paging examples
                 Key: OSLCCORE-150
                 URL: https://issues.oasis-open.org/browse/OSLCCORE-150
             Project: OASIS OSLC Lifecycle Integration Core (OSLC Core) TC
          Issue Type: Bug
          Components: Query
            Reporter: David Honey
            Assignee: James Amsden


The OSLC Query 2.0 specification does not give any examples of paging. If LDPC paging is used then the examples shown in https://www.w3.org/2012/ldp/hg/ldp-paging.html are insufficient. The issue is that most implementations will want to use a stateless paged query. This means that a query request to get page N of the results MUST repeat the query expression in oslc.where, oslc.select, oslc.orderBy. It would be better if the query spec included examples showing this.

Also, since one cannot determine ordering within a query response (see https://issues.oasis-open.org/browse/OSLCCORE-143), it's not clear how a server constructs a query for the next page. If the query result included some form of sequence number, then thge next page URI could include a query parameter for the next sequence number.

If we conclude that we should return some form of ordering triple for each member (perhaps oslc:sequence), then that could be used to support explicit ordering and page sequenciing.
