Data about exposure limitsEdit

Just have a look at Wikidata: WikiProject Chemistry to see some informations and feel free to contribute to the development of tools or guidelines in that field. For exposure limits we need a special datatype: the numeric datatype with unit. This is not yet implemented but should be available in the next months (follow that bug to know the progress of that feature.

But we can already develop the structure to store that data by launching the discussions about the properties which will used to store the data with the relevant indications and sources. This can be done under Wikidata:Property_proposal and more specifically under Wikidata:Property_proposal/Natural_science#Chemistry_.2F_Chemie_.2F_Chimie_.2F_.D0.A5.D0.B8.D0.BC.D0.B8.D1.8F. But feel free to use others sections or to create a new one if necessary. Just be aware that few persons are looking at that page regularly so better use the current system or do a good marketing job to attract people. Snipre (talk) 11:59, 28 May 2015 (UTC)

@Snipre: Thanks so much for the message! I will check out WikiProject Chemistry over here and the bug as well. I'm still quite the newbie over here, so if I do something wrong I apologize in advance. Best, Emily Temple-Wood (NIOSH) (talk) 21:31, 28 May 2015 (UTC)

NIOSH dataEdit

Further to our conversation at en:Wikipedia talk:WikiProject Chemistry#International OSH data...

The example you gave was, for "Oxirane, ( (2 - propenyloxy) methyl)", which I take (from the CAS registry number) to be allyl glycidyl ether (Q2467070).

It would be helpful to have 3 or four other examples, with the equivalent Q item, please.

It would then be useful to know what "RRD59F8" represents. Is it an identifier for the chemical (i.e. do you use that string elsewhere, in NIOSH or outside it, to refer to the same chemical?) or is it simply an identifier for that document? Is it persistent? How is it generated? Is there a table of such values, and equivalences?

Similarly the identifier "RTECS #: RR0875000".

What is the license on this data?

Once we have the answer to thee Qs, we can propose a Wikidata property to include that identifier for any relevant chemical.

One that is approved and in use, we can propose properties for as many of the individual statistics that you have, as the community deems sensible. We can then look to automating the import of the data.

If you publish linked data, the later will be much easier, and we can also include details of the relevant URI pattern. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 10:31, 29 May 2015 (UTC)

@Pigsonthewing: Thank you so much for your message! I really appreciate the help. Here are 3 examples:

One thing I've noticed is that many chemicals badly need alternate names added so they're easier to find. That's something I can easily take care of once I know I'm doing it correctly.

RTECS is an identifier for that document, it is persistent, but you have to pay for the whole database, which I don't have access to, but you may through the Royal Society. The RTECS pages available on the NIOSH website are the ones that correspond to everything in the PGCH. I'm sorry but I don't know how we can publish linked data or what a URI pattern is - I'm definitely a data novice. Thanks so much for your help. Best, Emily Temple-Wood (NIOSH) (talk) 02:37, 30 May 2015 (UTC)

Thank you for the extra examples and answers. What about "RRD59F8"? My concern now is about how we are are going to populate a new property, if the database is subscription-only? To answer the more general points, publishing en:linked data would be something for your web team; but won't be trivial. A URI pattern would describe the URIs used for such linked data, just like Wikidata describes the URL pattern for your PDFs as "$1.html", where "$1" represents the unique identifier, such as "RRD59F8". Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 19:19, 30 May 2015 (UTC)
I think we can populate the property with the identifiers from the PGCH for now, while I work on getting access to the RTECS database as a whole. Does that sound good? Emily Temple-Wood (NIOSH) (talk) 20:23, 30 May 2015 (UTC)
Sorry; what is PGCH? And we still need to determine whether the URL stem "RRD59F8" is a permanent identifier, that we can rely on (i.e. when the data is updated, for the same chemical, does it change?). Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 20:31, 30 May 2015 (UTC)
@Pigsonthewing: Ah, sorry, I replied in a bit of a hurry. The PGCH is the en:Pocket Guide to Chemical Hazards, a publication that has safety data on several hundred chemicals. The "RRD59F8" identifiers are permanent, yes. So we can use those. Emily Temple-Wood (NIOSH) (talk) 02:04, 31 May 2015 (UTC)

NIOSH data: licenseEdit

Hi, I don't find any disclaimer about right or license for the NIOSH Pocket Guide. Do you know what kind of policy exist about the use and reuse of data from CDC ? For example all data in WD are under CC0 license. If we add data under that license, we should be sure this won't be a problem. Thank you Snipre (talk) 11:32, 10 June 2015 (UTC)

@Snipre: Hi Snipre, I'm pretty sure it falls under the US government work licensing (public domain). Emily Temple-Wood (NIOSH) (talk) 19:08, 10 June 2015 (UTC)

Density of magnesite and gypsumEdit

Hello Emily Temple-Wood (NIOSH)
If I'm right then "density" is mass per volume in English speaking countries, the dimensionless quantity is "relative density" or "specific gravity". Thanks. Regards --Chris.urs-o (talk) 03:44, 26 September 2015 (UTC)
@Chris-urs-o: Yes, I keep trying to add the correct units and it's not letting me - I think we're just waiting for them to be created. I figure it's better to get the numbers added now and go through and add the units as soon as they're available. All of those are densities in g/mL or g/cm3. Do you have the appropriate userrights to make that happen? Best, Emily Temple-Wood (NIOSH) (talk) 03:46, 26 September 2015 (UTC)
@Chris.urs-o: Fixing ping, sorry. Emily Temple-Wood (NIOSH) (talk) 03:47, 26 September 2015 (UTC)
Don't panic ;) Wikidata doesn't accept <sup>3</sup>. Use instead: [αβγδφωλμπ][₎₍₋₊ₓ][₀₁₂₃₄₅₆₇₈₉][⁰¹²³⁴⁵⁶⁷⁸⁹][⁾⁽⁺⁻ⁿ]·☐. I think 'ml' is better than 'mL'. If things get complicated ask WD:Project chat, experts will try to help you. Is my edit acceptable? Regards --Chris.urs-o (talk) 03:59, 26 September 2015 (UTC)
Ah, thank you so much! I learn something new every day! :) Best, Emily Temple-Wood (NIOSH) (talk) 04:03, 26 September 2015 (UTC)
P.S.: anyone may create an item. It is no problem if you follow notability guidelines. Regards --Chris.urs-o (talk) 04:09, 26 September 2015 (UTC)
We don't wait any more: we have the datatype with unit. use density (P2054). Snipre (talk) 11:54, 26 September 2015 (UTC)
@Snipre: She is using it, how do we insert the unit as qualifier? --Chris.urs-o (talk) 16:56, 26 September 2015 (UTC)
@Chris.urs-o: Clic on "edit" of the statement, and you will see a window appearing below the value with the label "Unit (optional)" Clic in the editing window and type the name of the unit you want to specify like "kilogram per cubic meter" (Q844211). Then select the appropriate unit and save. If you don't find the unti you have to create a new item for that unit. Snipre (talk) 19:13, 26 September 2015 (UTC)
Thank you both! I'll go through and fix this posthaste. Emily Temple-Wood (NIOSH) (talk) 23:36, 28 September 2015 (UTC)
If you need more info about which items to use for units, see wikidata:units. Snipre (talk) 09:55, 29 September 2015 (UTC)
Hello, I see that you use a lot density (P2054). Can you just add the qualifier phase of matter (P515) with liquid or gas as value ? This will help a lot later to screen data. Thanks. Snipre (talk) 12:55, 5 October 2015 (UTC)
Sure thing! Emily Temple-Wood (NIOSH) (talk) 00:51, 8 October 2015 (UTC)


Dear Emily Temple-Wood,

could you cite any source for the density values you added? (e.g. captan (Q2194382))--Kopiersperre (talk) 08:52, 23 October 2015 (UTC)

@Kopiersperre: Yes, I'm working on it. :) Emily Temple-Wood (NIOSH) (talk) 16:18, 23 October 2015 (UTC)
Is it "NIOSH Pocket Guide"? I think that you could create an item for the booket and ask for a bot to add it... Regards --Chris.urs-o (talk) 04:12, 24 October 2015 (UTC)

Blistering agentEdit

Hi Emily,

may I merge blister agent (Q662959) with blister agent (Q21863971)?--Kopiersperre (talk) 16:50, 8 March 2016 (UTC)

@Kopiersperre: That makes sense - they're the same thing. Best, Emily Temple-Wood (NIOSH) (talk) 03:36, 9 March 2016 (UTC)

Please have a look at the property documentationEdit

Hello, I saw your edits concerning benzyl chloride (Q412260) and your data import about minimal lethal dose (P2300). Please can you use the data structure defined in the talk page of the property when adding data ? In the case of minimal lethal dose (P2300), the specie used to test the concentration should be defined using applies to taxon (P2352) and not afflicts (P689). I know, this is sometimes difficult to choose the right property but most of the time everything is defined in the talk page. Thanks Snipre (talk) 07:42, 11 July 2016 (UTC)

@Snipre: Ah, thanks for letting me know! I'll fix it straightaway. Emily Temple-Wood (NIOSH) (talk) 20:05, 11 July 2016 (UTC)

Hello, I think you should use applies to taxon (P2352) not found in taxon (P703) with properties related to toxicological doses and concentrations (aspirin (Q18216), 1,1,2,2-tetrabromoethane (Q161271), acetonitrile (Q408047)). Best, ∼Wostr (talk) 11:10, 14 July 2016 (UTC)

I suppose that does make more sense. I'll go through those and touch up when I have a minute. Emily Temple-Wood (NIOSH) (talk) 16:05, 19 July 2016 (UTC)

Item to be deleteEdit

In RFD there are one or more item proposed for the deletion created by you. If you do not agree you can participate in the debate --ValterVB (talk) 21:35, 3 March 2017 (UTC)
