Andy Seaborne commented on JENA-2039:
-------------------------------------
Syntactically, that scheme is fine. It is "path-absolute" production in the
RFC3986 grammar. I've added "path-absolute" to the Jena test suite :).
The use of fragment is legal but maybe a hierarchical path would be useful?
wm:/content/graphname
because used as a base, it becomes a base of wm:/content/ (assuming graph name
does not have "/" in it).
Just "wm:/content#graphname" then:
Base: "wm:/abcde#graph"
Relative reference "xyz"
=> wm:/xyz
Relative reference "#xyz"
=> wm:/abcde#xyz
whereas
base = "wm:/abcde/graph
"xyz" => "wm:/abcde/xyz"
(Strictly, in RFC 3986, the base does not have a fragment whereas Jena ignores
them)

> URI parsing fails

> Key: JENA-2039
> URL: https://issues.apache.org/jira/browse/JENA-2039
> Project: Apache Jena
> Issue Type: Bug
> Components: RIOT
> Reporter: Florian Kleedorfer
> Priority: Critical
>
> Depending on 3.18.0-SNAPSHOT, some of my tests started to fail recently. We
> are using URIs of the form 'wm:/abcde' - note the single slash. These URIs,
> it seems, can no longer be parsed.
> Here is a minimal example:
> {noformat}
> @prefix msg: <https://w3id.org/won/message#> .
> <wm:/jq15ga3aacsxbvl9nngw> a msg:Message .
> {noformat}
> This is the exception I get:
> {noformat}
> Exception in thread "main" org.apache.jena.riot.RiotException: [line: 3, col:
