The complete Facebook friendship network among the 769 users of the Caltech36 Facebook network in September 2005, one of the 100 college and university networks of the Facebook100 collection. It holds 16,656 undirected friendship links between users of the same school (links to other schools are not included), and seven anonymised attributes for each user: a student/faculty status flag, gender, major, second major or minor, dorm or house, class year and high school. Users are identified only by their row number in the original file. Per the papers, the demographic information was volunteered by users on their own pages; where a user gave none, the original codes the value 0, which this package reads as missing. The data were sent to the authors in anonymised form by Adam D'Angelo of Facebook and analysed by Traud, Mucha and Porter. The original file is a MATLAB .mat file holding a sparse adjacency matrix and an attribute matrix.
A network of Facebook pages in the category 'food', as Network Repository distributes it: its description says that the data were collected about Facebook pages in November 2017, that the pages are blue-verified, that nodes represent the pages and that edges are mutual likes among them. This copy holds 2,102 mutual likes among 620 pages and a node table of 620 pages with their names and Facebook page IDs.
The Friendica federation graph of the Fediverse as crawled by the Fedivertex project: 59 snapshots taken between 3 February 2025 and 14 April 2026. In the upstream documentation this is a federation graph: if two instances know each other they are connected, and the graph corresponds to the undirected communication graph between instances. The package holds 2,158,557 links, each with the snapshot it was seen in, and 14,926 instance records (594 distinct instances; one record per instance per snapshot) with the attributes upstream recorded (`version`, `users`, `statuses`, `registration_enabled`, `error`). A snapshot lists between 214 and 364 instances and between 29,852 and 67,199 links. Every link has weight 1. Instance names are written with "[DOT]" in place of each dot, exactly as upstream published them. The graph is declared undirected. Fedivertex covers 13 such graph series (seven Fediverse software systems and several kinds of relation); this package is the Friendica federation series only.
The Lemmy cross-instance graph of the Fediverse as crawled by the Fedivertex project: 24 snapshots taken between 3 February 2025 and 14 July 2025. In the upstream documentation this is a cross-instance graph: two instances are connected as soon as there exists a pair of users who published a message in the same thread, possibly on a third instance; an undirected graph, less sparse than the intra-instance graph. The package holds 99,867 links, each with the snapshot it was seen in, and 9,878 instance records (557 distinct instances; one record per instance per snapshot) with the attributes upstream recorded (`version`, `users`, `posts`, `comments`, `communities`, `users_active_day`, `users_active_week`, `users_active_month`, `users_active_half_year`, `captcha_enabled`, `require_email_verification`, `description_language`). A snapshot lists between 362 and 439 instances and between 3,244 and 5,246 links. Edge weights are whole numbers from 1 to 1,719 (470 distinct values). Instance names are written with "[DOT]" in place of each dot, exactly as upstream published them. The graph is declared undirected. Fedivertex covers 13 such graph series (seven Fediverse software systems and several kinds of relation); this package is the Lemmy cross-instance series only.
The Lemmy intra-instance graph of the Fediverse as crawled by the Fedivertex project: 24 snapshots taken between 3 February 2025 and 14 July 2025. In the upstream documentation this is an intra-instance graph: instance X is linked to instance Y if a user of X has published a message on instance Y; the graph is directed and very sparse. The package holds 24,692 links, each with the snapshot it was seen in, and 9,878 instance records (557 distinct instances; one record per instance per snapshot) with the attributes upstream recorded (`version`, `users`, `posts`, `comments`, `communities`, `users_active_day`, `users_active_week`, `users_active_month`, `users_active_half_year`, `captcha_enabled`, `require_email_verification`, `description_language`). A snapshot lists between 362 and 439 instances and between 797 and 1,133 links. Edge weights are whole numbers from 1 to 86,402 (1,102 distinct values). Instance names are written with "[DOT]" in place of each dot, exactly as upstream published them. The graph is declared directed. Fedivertex covers 13 such graph series (seven Fediverse software systems and several kinds of relation); this package is the Lemmy intra-instance series only.
The federation network of BookWyrm, the federated social network for reading and reviewing books, as crawled by the Fedivertex project: 62 snapshots of the network taken between 3 February 2025 and 13 April 2026. In the upstream documentation, two instances (servers) are connected in a federation graph if they know each other, and the graph is the undirected communication graph between instances. The package holds 171,615 links, each with the snapshot it was seen in, and 4,313 instance records (151 distinct instances; one record per instance per snapshot) with the software version, whether registration was enabled and, in 49 of the snapshots, the language of the instance's description. A snapshot lists between 55 and 103 instances and between 1,949 and 4,435 links. Every link has weight 1. Instance names are written with "[DOT]" in place of each dot, exactly as upstream published them. Fedivertex covers 13 such graphs (seven Fediverse software systems and several kinds of relation); this package is the BookWyrm federation graph only.
