I must admit, I'm not up to SPARQL as I probably should be but it strikes me that earl:Assertion is not a variable. Also, isn't earl:result actually a -bnode?

In RDQL I've been working with queries like this to return all assertions for a <QUERY-URL> (which automatically assumes the type earl:WebContent for the subject):

---
?assertion, earl:subject, ?subject
?assertion, earl:result, ?bnode
?assertion, earl:mode, ?mode
?assertion, earl:testcase, ?testcase
?assertion, earl:assertedBy, ?assertor
?bnode, earl:validity, ?validity
?bnode, earl:message, ?message
?bnode, earl:confidence, ?confidence
?subject, earl:reprOf, <QUERY-URL>
?subject, dc:date, ?date
---

Two more queries are required to fetch the information about tool- and human- type assertors. For example:

---
?assertor, earl:name, ?name
?assertor, earl:email, ?email
---

How would that look in SPARQL? (yeah, I know I should go RTFM)

Best,
