Hi,

Thanks for the great project! I've noticed that in the extracted JSONL files, there is no name for 'property_id'. Could you please provide some guidance or suggestions on how to accurately extract the name of 'property_id'? Any help would be greatly appreciated!

Hi,

Thank you for the useful github code.

When I run the code in preprocess_dump.py to process the lastest wikidata dump (as of April 16) with 28 processes, I got the following error with processes 28. However, the code seems still running and produce processed tables.

Do you know if the error is something I should care about or I can just ignore it?

Thank you a lot!

Process Process-28: Traceback (most recent call last): File "**/lib/python3.8/multiprocessing/process.py", line 315, in _bootstrap self.run() File "**/lib/python3.8/multiprocessing/process.py", line 108, in run self._target(*self._args, **self._kwargs) File "**/simple-wikidata-db/simple_wikidata_db/preprocess_utils/worker_process.py", line 151, in process_data out_queue.put(process_json(ujson.loads(json_obj), language_id)) File "**/simple-wikidata-db/simple_wikidata_db/preprocess_utils/worker_process.py", line 91, in process_json datatype = claim['mainsnak']['datatype'] KeyError: 'datatype'

Hi! Great project. I've been trying to extract the links to Wikipedias, and am guessing that this info should be in the wikipedia_links files, but is missing.
According to this example, WikiBase JSON, there should be info such as:

{
  "sitelinks": {
    "afwiki": {
      "site": "afwiki",
      "title": "New York Stad",
      "badges": []
    },
    "frwiki": {
      "site": "frwiki",
      "title": "New York City",
      "badges": []
    },
    "nlwiki": {
      "site": "nlwiki",
      "title": "New York City",
      "badges": [
        "Q17437796"
      ]
    }
}

This info is displayed in the Wikipedia section of a WikiData page.
However, the wikipedia_links files only contain this data:

qid: the QID of the entity
wiki_title: link to corresponding wikipedia entity

Ex:

{"qid":"Q23","wiki_title":"George Washington"}

So, there is no reference to the language of the wikipedia.
Is there any chance of Wikipedia sitelinks getting added to a future version?

Hi @neelguha! this is neat. It is close to the concerns of some in the Wikidata community around "subsetting", so I've linked it from the Tools section in https://www.wikidata.org/wiki/Wikidata:WikiProject_Schemas/Subsetting#Tools_and_Data

One of the reasons folk are interested in Wikidata subsets is that it can be too large a dataset to work with comfortably - so pulling out just the bits most relevant to some application is appealing. There's also a concern to encourage offsite usage of the data so that the load on query.wikidata.org remains manageable while the project and datasets grow. In both cases, tools like yours seem relevant, although the problem of characterising what goes in the subset can be tricky.
