For indie artist contracts we may have the problem of having to create many transformers and extractors

[TimDaub]

• Consider that there are two artists A and B that both launch independent NFT collections C_a and C_b and then those implement function tokenURI but the JSON schema they are using is that for e.g. C_a the the audio manifestation is at the property mp3_link and for C_b it's at lossless_Audio.
• Then potentially in this case, first of all, there is no generic "crawl this NFT collection" strategy
• But also, we'd have to manually implement a transformer for C_a-get-tokenuri and for C_b-get-tokenuri
• Additionally, in neume-network/data, since we're relying on e.g. block event logs information for tracking when an NFT was minted, someone like me with access to an Erigon full node also has to manually update the call-block-logs-transformation file
