Canonical JSON (keys sorted, no spaces, UTF-8). Its SHA-256 is the hash on chain. The abstract here is gemini shortened, not the author's own text.

{"abstract":"This study developed and validated Knowledge-Based Activities in Chemistry for twenty-one (21) scientifically challenged Grade 7 learners at Lagundi-CCL National High School. The activities included four (4) motivational, four (4) group task, and fourteen (14) individualized task activities covering solutions, substances and mixtures, periodic table, elements and compounds, acids and bases, and properties of metals and non-metals. Descriptive, developmental, and experimental methods were used, with mean, standard deviation, dependent t-test, and weighted mean for data analysis. Before exposure, participants performed Fairly Satisfactory in solutions, substances and mixtures, elements and compounds, and acids and bases, improving to Very Satisfactory after. For properties of metals and non-metals, performance improved from Fairly Satisfactory to Outstanding. A significant difference in performance was observed after exposure to the material. Ten (10) Chemistry teachers evaluated the activities as Very Highly Acceptable. The study concluded that the developed activities significantly improved learners' performance and are a highly acceptable instructional device.","abstract_source":"gemini_shortened","authors":["Neil Fernando"],"date":"2022-10-14","doi":"10.5281/zenodo.7197260","id":677,"issue":2,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"34f22b98b339c607692b52a81c33d8f96dc719ce1fc79823dc5ae73ae2f3c458","schema":"scimatic-article/1","title":"Knowledge-Based Activities in Chemistry for Scientifically Challenged Learners of Grade 7","volume":5}

Check it yourself

1. The record, from the token's own metadata:

printf '%s' "$(curl -s https://scimatic.org/nft/articles/677.json | jq -r .canonical_record)" | sha256sum

2. The hash stored on chain (contentHash(677)):

curl -s https://rpc.scimatic.net -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_call","params":[{"to":"0x0E596B4bb924937aA35D9b342A90347ed6F05eF8","data":"0xf3e0c29000000000000000000000000000000000000000000000000000000000000002a5"},"latest"]}'

The two must be equal (the second with a 0x in front).
