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 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

+description = r"""Directed network of follower relationships among Twitter users who took part in the online activity around the 15-M (Indignados) protest movement in Spain, collected from 25 April to 25 May 2011. The messages were collected by Cierzo Development Ltd. and include only messages in Spanish related to the movement, identified by a set of hashtags. The network includes users who sent at least one message on the topic, or who were mentioned by a user who did, and contains only the follower relationships among these users (87,569 nodes). The data were made available by Y. Moreno and J. Borge-Holthoefer.
+
+Edges follow the direction of the information flow: an edge $i \to j$ indicates that user $j$ follows user $i$.
+
+The upstream data also contain the time, hashtags and mentions of the collected messages, which are not included in the network. The node properties `id` and `name` hold the (meaningless) node labels of the upstream Pajek file, and the edge property `weight` is always 1."""
