在模型派生API（使用DbIds进行OBJ提取）中，我使用API检索了OBJ URN。如下所示，它返回obj，mtl及其zip的所有子级URN。每个孩子确实都有自己的向导，我们如何确定最近的拔牙？
我附加了整个响应JSON。我正在寻找的是第二个obj文件，该文件已使用“ 17,19,21,22,23 ...”之类的多个dbid提取。第一个子obj是很久以前创建的。如何区分新的obj。因为GUID对于每个节点都是不同的。如何确定哪个GUID.obj属于我想要的提取。
**编辑** 我正在寻找标识提取的波前对象文件（而不是从元数据中获取的objectid和名称）。假设如果我从一个模型中提取了2个目标文件，那么在完成目标文件几何图形提取作业之后，将生成6个文件并将其存储在存储桶中。
每个文件都具有不同的GUID.Type作为名称。并且那些guid是随机的，在调用提取API或获得进度时不会显示。
这些显示在下面的JSON文件中。现在假设我从一个模型中提取了10个不同的目标文件。这意味着将在存储区30中生成新文件URN。 而且变得越来越难以识别。
如果我从模型中提取obj几何，则解决方案应该是，我应该获取特定的obj，mtl，zips guid。如果我仅获得3个ID，则可以将其映射并从存储桶中下载。 现在发生的是，在调用get manifest GET :urn/manifest之后，我将获得所有obj的guid（假设为30）。而且我不了解哪个obj文件属于哪个提取。

{
"data": {
"type": "metadata",
"metadata": [
{
"name": "Scene",
"role": "3d",
"guid": "4f981e94-8241-4eaf-b08b-cd337c6b8b1f",
},
{
"name": "Sheet: A101",
"role": "2d",
"guid": "8e7c6bca-cfd1-290e-4b16-f3670169bb71"
}
]
}
}
然后使用GET :urn/metadata/:guid检索对象树以标识派生对象：
{
"data": {
"type": "objects",
"objects": [
{
"objectid": 1,
"name": "A5",
"objects": [
{
"objectid": 2,
"name": "Model",
"objects": [
{
"objectid": 3,
"name": "Bottom",
"objects": [
{
"objectid": 4,
"name": "Box"
}
]
},
