SPARQL删除查询错误：EOF在解析

Question

我试图删除使用此查询一些三元：

deleteQuery = """DELETE { ?a ?b ?c } WHERE { mynamespace:List mynamespace:Item ?c. ?a ?b ?c }"""

My命名空间已被定义，所以这不是一个问题。 虽然我不确定是否使用了正确的查询语法。 当我发出查询我得到这个错误：

400 EOF while parsing. Expected terminals: (prefix describe sum correlation select average modify insert median load ask construct clear count stats delete). Traceback (most recent call last): File "<stdin>", line 1, in <module> File "triple_store_methods_v2.py", line 40, in query myResults = myTupleQuery.evaluate() File "/usr/local/agraph-fse-3.3/python/franz/openrdf/query/query.py", line 358, in evaluate response = self.evaluate_generic_query() File "/usr/local/agraph-fse-3.3/python/franz/openrdf/query/query.py", line 239, in evaluate_generic_query checkVariables=self.checkVariables, accept=accept) File "/usr/local/agraph-fse-3.3/python/franz/miniclient/repository.py", line 80, in evalSparqlQuery accept=accept) File "/usr/local/agraph-fse-3.3/python/franz/miniclient/request.py", line 114, in jsonRequest else: raise RequestError(status, body) franz.miniclient.request.RequestError: Server returned 400: EOF while parsing. Expected terminals: (prefix describe sum correlation select average modify insert median load ask construct clear count stats delete).

我不明白我在做什么错。顺便说一句，我使用AllegroGraph 3.3。

我猜，Allgegrograph（至少3.3版本）还不支持SPARQL更新。
