Data, code, figures, and the manuscript for The architecture of internet aesthetics (Y. J. Lin, Cornell University).Contents: (1) the internet-aesthetics ecosystem network of 1,115 aesthetics joined by 5,889 community-authored related-links, with community, affect, and era attributes and a self-contained interactive HTML explorer (pan / zoom / search); (2) the are.na human-label and co-curation records; (3) an openly-licensed 681-image stimulus corpus from Wikimedia Commons with per-image attribution (CREDITS.md) and a 681x37 perceptual and mechanism feature table; (4) three-model frontier vision-language affect ratings over the are.na images, from gemini-2.5-flash, gpt-4o, and claude-sonnet-4-6; (5) OASIS benchmarking and mechanistic-intervention (image-edit and prompt-reframe) outputs; and (6) all harvest, analysis, and figure code.The are.na images themselves are copyright-held and are NOT included in this archive; only derived features and model ratings are released. The 681 Wikimedia images ARE included, each retaining its own CC / public-domain licence (see CREDITS.md and LICENSES.md). The dataset compilation (manifests, feature tables, ratings, network, and code) is released under CC-BY-4.0.
