ISSUE-47: What happens when rr:column, rr:template etc produce invalid IRIs?

invalid-iris

What happens when rr:column, rr:template etc produce invalid IRIs?

State:
CLOSED
Product:
R2RML
Raised by:
Richard Cyganiak
Opened on:
2011-06-21
Description:
What happens when rr:column, rr:template etc produce invalid IRIs?

Is this an error? Is it a warning? Is the triple ignored? Is it automatically %-encoded?

Also, what exactly is a valid or invalid IRI? In particular, is it relative or absolute? If relative, then with respect to what base IRI?

Related notes:

The Editor's Draft now specifies:
- rr:template with term type “IRI” %-encodes any character that is not in iunreserved
- generate IRIs only if the value is a valid IRI, or results in a valid IRI after prepending the base IRI
- otherwise, don't generate a triple

This gives quite a bit of flexibility (use rr:template when you want to encode), while ensuring reversibility for SPARQL.

Changing state to OPEN again as there has been considerable discussion about this and consensus doesn't appear to be achieved

Oops, I should have set the status back to RAISED as there was no WG decision to open this issue yet
