Motivation edit

The proposed property would be helpful for readers to know what substances are covered in the reference work. --Leiem (talk) 12:16, 13 December 2023 (UTC)[reply]

Discussion edit

This approach is fine, but seems incomplete in that it doesn't make the queryable connection to journal articles where these pathways were discussed does it? In the second case these links seem to be under [1] cites work (P2860), which seems to me to be a distortion of its original intent, since that is supposed to be between one scholarly work and another. --99of9 (talk) 02:19, 21 December 2023 (UTC)[reply]
I might be misunderstanding you, but if we have a separate entity for the reaction, I think main subject (P921) (and described by source (P1343) for the reverse direction) are exactly the right properties to link it with the corresponding article. 2620:15C:161:107:9977:4897:47AD:5467 02:30, 29 December 2023 (UTC)[reply]
It strikes me that the distinction you're making is really main subject (P921) vs. "secondary topic". There's nothing specific to the topics being chemical substances. 2620:15C:161:107:9977:4897:47AD:5467 02:27, 29 December 2023 (UTC)[reply]
