2026-11-03 [entries] Prefix the properties in the descriptions with (Node), (Edge) or (Graph) by Tiago de Paula Peixoto bc3dbbd

The lists of properties at the end of the descriptions marked edge
properties with "Edge" but left node properties unmarked, or grouped
them in "Nodes: `a`, ...; `b`, ..." items, so the kind of a property
was often unclear. Every item now starts with (Node), (Edge) or (Graph),
followed by the property names, a colon and the explanation, one item
per property or group of properties; qualifications (kinds of nodes,
networks) follow the names in parentheses. Properties that were only
named got a short explanation, and a few items that named the wrong
kind of property were corrected.

2026-11-02 [entries] Remove unneeded code from the entries by Tiago de Paula Peixoto 2c69f19

Unneeded "global files" statements, unused imports and variables,
f-strings without placeholders, duplicate keys in foodweb_little_rock
(keeping the order and the values used), and the second definition of
get_lines() in twitter_higgs. Nothing changes in the networks or
descriptions.

2026-10-25 [entries] Move more KONECT-derived entries to their original sources by Tiago de Paula Peixoto bf9dc0e

The entries now download the data from where KONECT obtained them (live,
or via the Wayback Machine), using the same release as KONECT where it is
still available, and gain the metadata KONECT dropped; descriptions and
citations are rewritten from the original sources:

- Linton Freeman's UCINET data page: bible_nouns, bison, cattle, hens,
  highschool, kangaroo, macaques, moreno_sheep, physician_trust (the three
  relations and the physicians' attributes), rhesus_monkey,
  train_terrorists, windsurfers (now the networks `interaction` and
  `closeness`), college_freshmen, crime, interactome_yeast (from the
  primary source), moreno_taro (undirected), residence_hall, zebras
- other pages, archived: contiguous_usa, advogato, google, github,
  digg_reply, twitter, bookcrossing, dbtropes_feature (without KONECT's
  spurious "ItemName" tropes)
- movielens_100k (in fact the MovieLens 10M tag assignments)
- dblp release 2017-05-02: dblp_author_paper, dblp_cite, dblp_coauthor
- DBpedia 3.9: dbpedia_country, dbpedia_genre, dbpedia_location,
  dbpedia_occupation, dbpedia_producer, dbpedia_recordlabel,
  dbpedia_starring, dbpedia_team, dbpedia_writer, dbpedia_all, dbpedia_link
- Discogs releases dump of October 2015: discogs_affiliation,
  discogs_genre and discogs_label (now with genre and style networks)
