Abstract

Various interoperability test-beds at OGC, in particular OWS-7 and OWS-8, have applied OGC’s WFS 2.0 and FES 2.0 standards on AIXM 5 data. Though it could be demonstrated that a basic interoperability is possible, it turned out that some key requirements could not be fulfilled. This paper summarizes the observations made and shows that these requirements are not specific to AIXM 5, but more generally apply to any data model featuring temporality. To overcome these shortcomings, a proposal is made for an extended type of WFS query: a dynamic feature query.
