A couple of questions about this property
[edit]Hi, I am new to Wikidata. I work as a contractor for the NLM, so this property caught my eye. I have a couple of questions.
- Why was it changed to string? AFAIK, these identifiers are integers. I'm not 100% sure of that, but I could check. Wouldn't it be better to have the datatype match, if, in fact, these are integers?
- Is there guidance anywhere on how this should be discovered / used, other than the JAMA example? If not, where would just documentation usually go? Here on the talk page? If it would be worthwhile, I could write some.
- I see that the domain is "creative work", and I'm wondering if that's right. JAMA is a journal, which is a container of creative works, but is it a creative work itself? Sorry if that's a dumb question.
- Related to that, where, on the The Journal of the American Medical Association (Q1470970) page, can I find that this item is a "creative work"? Is there an "is-a" property, that points to a class? If so, I can't find it.
Thanks! Klortho (talk) 05:35, 22 December 2013 (UTC)
- Klortho: I'm not sure if I'm 100% correct on some things, but this is what I think:
- On bullet one, the property is using the string datatype so that it can later (thanks to the software) point to the URL of the NCBI, as shown on The Journal of the American Medical Association (Q1470970). This wouldn't be possible using the integer datatype, apart from the fact that we don't have yet an integer datatype available. Also, a FYI, the datatype of a property cannot be changed.
- On bullet two: Well, actually you can add this property to any item which has such an ID. I have no idea which items need this property (I guess you could find it using the National Library of Medicine registry, just like you find a song's writer on the liner notes). About a proper documentation, I think that the box atop this page is such thing.
- On bullet three: The domain was an internal classification used on Wikidata, now deprecated, named "main type" (P107 (P107)). The domain of the property was specified as to belong to one of the "types" (creative work, term, etc) in relation to that property. Since the property's fate was decided on an RfC, it doesn't matter anymore.
- Since the main type property (P107 (P107)) is to be deleted, another property (instance of (P31)) is the one who takes over. This other property is way more flexible (for example, at The Journal of the American Medical Association (Q1470970), it would be instance of = journal).
- Hope this helps. — ΛΧΣ21 07:01, 22 December 2013 (UTC)
- Hi, thanks for the responses! Unfortunately, they just leave me with more questions:
- Are you saying that the value of this property for JAMA is "[http://www.ncbi.nlm.nih.gov/nlmcatalog/7501160 7501160]"? If so, why don't I see it that way when I click "edit" on the JAMA page? There, I just see the integer value. Where is the URL template rule (how to turn the integer into a URL) stored? Is *that* editable?
- If "Domain: creative work" is meaningless, why is it still in the documentation template? Can I take it out? I think, old and deprecated information should be cleaned up whenever possible.
- So, is there any formal way to code the domain of a property according to instance of (P31)? For example, any way to specify that the domain of this property must be a *journal*?
- I am thinking I will also leave some of these questions on Wikidata:Project_chat.
- Thanks again!

Change in formatter URL
[edit]I just changed the formatter URL as it was selective only for certain types of NLM entries. For example, Q19561861 wouldn't have worked, despite that the NLM ID was correct. The new one also searches the NLM catalog directory, rather than via the NCBI. I checked on multiple different files to be sure that it works before changing it. Of note, the query doesn't run correctly if all those arguments aren't there. It may look busy, but it is a library search. Hazmat2 (talk) 18:28, 12 March 2015 (UTC)
- Noticed that the formatter URL was changed to one that didn't work for many of the IDs, so I checked the site and the catalog is still using the old search function so I reverted it back. Rehua (talk) 01:38, 13 June 2019 (UTC)
- @Rehua: @Hazmat2: Note that https://www.ncbi.nlm.nih.gov/nlmcatalog/9422792, for example, is not identical with https://locatorplus.gov/cgi-bin/Pwebrecon.cgi?v2=1&ti=1,1&SEQ=20190925031111&Search_Arg=9422792&Search_Code=0359&CNT=25&PID=Lsj0-1SSUUeHM8ZLDwQvsk&SID=1 which is the detailed view option (rather than the default summary view). The NCBI version has additional fields, such as Publication Start Year for inception (P571), Country of Publication for country of origin (P495) and Coden for CODEN (P1159). So even if people know to go to the detailed view, they are not getting the best data at present. Charles Matthews (talk) 07:31, 25 September 2019 (UTC)
NLM new catalog 2021
[edit]NLM has moved to a new catalog and all of these links will stop working soon as LocatorPlus is phased out of use. I have updated the formatter URL and format of regular expression to direct people to the new catalog through Primo. I wanted to explain the change here for anyone who was curious.

Format constraint
[edit]Why is the Format constraint \d{6,8}(A|R|\d) when all other references to the value are \d{6,19}(A|R|\d)? I have a journal Q116671798 which has a 16-digit value. The generated link works fine, but it is being flagged as a format constraint issue. Keith Edkins (talk) 21:16, 14 November 2024 (UTC)
