Hi,
We are planning to use RDF Patch and RDF Delta
(https://github.com/afs/rdf-delta) to edit our TDB dataset served through a
fuseki endpoint. We took a look at various docs pertaining to Delta and Patch
and browse the github repo, but we are still wondering about what could be the
best
great, simple is good here Lorenz. I tried $1 but was surprised to get
full strings bound to ?email on non-matches here as well. I had to
combine it with a filter of the same pattern to get the desired
results. so I read the replacement semantics here now that
backreference $0 is the input string
Or maybe even more simple
|BIND(REPLACE(STR(?url),".*/([a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+)/.*","$1")
AS ?email)|
>> BIND (REPLACE(STR(?s),"[a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+","$0") AS ?email)
> replaces the matching email address by the email address itself, so it's
> the same as before.

> BIND (REPLACE(STR(?s),"[a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+","$0") AS ?email)
replaces the matching email address by the email address itself, so it's
the same as before.
You need to replace everything else by the email address, replace is not
an "extract" function, you can try
BIND
