使用以下 bash 脚本上传海龟数据：

#!/usr/bin/env bash
RDF4J_ENDPOINT=endpoint_uri
DIR="~/modelio/workspace/IPR/"
IFS=
FILE=tmp.rq

function runUpdateQuery() {
    cp $1 $FILE
    sed -i -e "s!__VOC_IRI__!$2!g" $FILE
    curl --netrc-file .netrc -X POST -H "Content-type: application/sparql-update" -T $FILE $RDF4J_ENDPOINT/statements
}

function transform() {
    VOC_IRI=$1
    PREFIX=$2

    URL="$RDF4J_ENDPOINT/rdf-graphs/service?graph=$VOC_IRI"
    curl --netrc-file .netrc -X POST -H "Content-type: text/turtle" -T "$DIR/$PREFIX-model.ttl" $URL
}

transform http://onto.fel.cvut.cz/ontologies/slovník/datový-psp-2016 psp-2016

词汇 IRI (.../slovník/datový-...) 中的变音符号失败，并出现以下错误：

删除变音符号后，它工作得很好。知道有什么问题吗？

GraphDB 使用 Unicode，特别是 UTF-8 编码来进行所有通过 HTTP 的通信。为了在 URL 中传递任何非 ASCII 内容，需要将其编码为 UTF-8。如果您这样使用，Curl 不会自动执行此操作。您可以手动对“í”和“ý”的 UTF-8 表示进行 URL 编码（%C3%AD 和 %C3%BD），也可以使用此 curl 功能：

curl -X POST -H "Content-type: text/turtle" -T file.ttl\
     -G --data-urlencode "graph=http://onto.fel.cvut.cz/ontologies/slovník/datový-psp-2016"\
     http://hostname:7200/repositories/repo/rdf-graphs/service

关键是 -G 选项，它告诉 curl 将 URL 编码的参数附加到 URL。
