How to set up the ID of a json element in rdflib
问题
{"@id": "_1234","@type": "cim:Substation","cim:IdentifiedObject.name": "A substation"}
英文:
Context
I am loading a rdf file in rdflib, and am trying to export it in json-ld.
The original rdf looks like:
<cim:Substation rdf:ID="_1234"><cim:IdentifiedObject.name>A substation</cim:IdentifiedObject.name></cim:Substation>
The exported json-lib looks like:
{"@id": "file:///path/to/original/xml#_418866779","@type": "cim:Substation","cim:IdentifiedObject.name": "A substation"},
I cannot seem to override the file:///path/to/original/xml component in json.
Code
This is what I am doing:
from rdflib import Graphg = Graph(# Giving an identifier or base does not seem to change anything)g.parse('path to rdf')js = g.serialize(format="json-ld",encoding="utf-8",destination='path to json',sort_keys=True, # repeatable output is Good.context={ some relevant entries (rdf, cim) },auto_compact=True,# giving base does not seem to change anything)
Question
How can I set/override the first component of the ID in the exported json-ld?

解决方案在parse方法中，使用参数publicID，该参数在源代码中有描述。
> 用作文档基础的逻辑URI。如果未指定，则使用文档位置（至少在存在文档位置的情况下）。
因此，我在问题中的示例变为
g.parse('rdf路径', publicID="#")
其余部分保持不变。
英文:
The solution was in the parse method, with the parameter publicID which is decribed in the source.
> the logical URI to use as the document base. If None
specified the document location is used (at least in the case where
there is a document location).
So my example in the question becomes
g.parse('path to rdf', publicID="#")
and the rest stays as is.
