Conflict of interest statement

Wikimedia has guides about conflict of interest and paid editing. Wikidata does not have strict policies but suggests to use common sense. Here is my statement:

I work at Wolfram Research.

This is my personal account and I do all my edits because I want to. I'm not being paid. At Wolfram, I work on semantic web technologies. If I come across missing or wrong data during my work time (I define that as being logged into my computer with my work account), say, while preparing examples for a talk or blog post, then I might improve the data. Overall, the number of edits I make during work time is negligible compared to all my edits.

Quantities and Units

Motivation

Quantities and units are part of the language of science.

By providing a Wikidata item (Q-number) for each quantity and unit ever used we facilitate unambiguous communication in science.
By providing labels and descriptions for each item in each language we help people to talk about science across language barriers.
