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] Fix parse bugs and improve descriptions and metadata by Tiago de Paula Peixoto 6bb6851

- parse fixes from the review of the descriptions, e.g. us_patents
  (directed), celegans_2019 (synapse direction), ecoli_transcription and
  yeast_transcription (regulator to target), bitcoin (direction, phantom
  node), ego_social (Google+ features and circles), scotus_majority,
  arxiv_authors and social_location (as in SNAP), caida_as, dnc, dom,
  mist, reuters and bibsonomy (names on the right nodes), uci_zoo
- every description now states explicitly what the nodes and edges
  represent; corrected titles, years, tags, citations and licences
- the "Hypergraph" tag is removed; very large entries are marked
  `huge = True` (see --skip-huge)
- ICON ids of partial duplicates added (hiv_transmission, congress_bills,
  openflights, dutch_school)

2026-10-25 [entries] Fix parse bugs and improve the metadata of existing entries by Tiago de Paula Peixoto c996a0e

From a review of the dataset descriptions against the upstream sources
and papers, and from user reports:

- parse fixes (wrong edge direction or directedness, shifted or
  misnamed properties, merged node identities, duplicated or missing
  edges and nodes, wrong types), e.g. arxiv_citation (the HepTh dates
  were a copy of the HepPh ones; now from the KDD Cup 2003 data),
  eu_procurements, foursquare_global, hiv_transmission, genetic_multiplex,
  gnutella (adds the 05 snapshot), roadnet, macaque_neural, python_dependency
- descriptions rewritten from the upstream sources, documenting every
  property
- corrected titles, citations and DOIs, licences (ustream_license typo,
  the data's own terms), tags and ICON ids
- url lists for entries with several sources or dataset pages
- SocioPatterns entries moved to the site's new data location, with the
  daily networks of sp_infectious and sp_primary_school
- the Michael Fire entries marked as orphans (served from the mirror)
- redundant type forcings removed after the graph-tool coercion fixes
