Hi Nicolas,
Temp graphs are not visible to certain parts of the system, such as the logic
that resolves imports.
I'm not sure if this will help you, but if you need to access a temp graph
together with some other graphs, the function ui:unionOfGraphs(?g1, ?g2, ...)
might be useful. This function returns a “magic” graph name that contains the
triples from all the argument graphs, and it works with temp graphs. For
example, this will work in SWP:
<ui:setContext ui:queryGraph="{= ui:unionOfGraphs(ui:tempGraph,
<urn:x-evn-master:my-asset-collection>)) }">
Wrapping the non-temp graph in ui:graphWithImports(...) will also work as
expected.
(Adding a UUID to the temp graph name is not necessary as temp graphs are
scoped to the currently running SWP engine instance, and each separate HTTP
request will get a separate SWP engine instance. Good practice is to choose a
temp graph name that is unique to your service/component, e.g.,
ui:tempGraphMyCustomExporter.)
