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

Nodes are students and edges denote implicit or explicit cooperation between two students while doing their homework assignments, as inferred by M. Fire et al. from the data collected during the course. There are three types of links, and a pair of students can be connected by several edges of different types.
+
+The network has the following properties:
+
+- `name`: the anonymous identifier of the student.
+- `type`: the type of link: `Partners` (explicit cooperation: the students submitted an assignment together), `Computer` (the students submitted assignments from the same computer), or `Time` (implicit cooperation inferred from the timing of the students' activity; see Fire et al. for the precise definitions)."""
