dct:description "Returns a single result row with one 'svg' column holding a complete SVG document rendering the ego trust network of an agent (the 'resource' parameter, typically the agent shown on a user page), computed dynamically from the nanopublication network. This is the query behind the 'Trust network' SVG view (gen:SvgView). The agent is shown as a central box; agents who endorse it (via npx:approvesOf on one of its introduction nanopublications) appear as boxes in a left-hand column with an arrow into the center, and agents it endorses appear in a right-hand column with arrows out of the center. Each side is capped at 15 boxes (ordered alphabetically by name), with a '+ N more' note when the cap is exceeded. Each neighbor box links root-relatively (/user?id=...) to that agent's user page and carries a colored dot reflecting the agent's status in the current trust state of the nanopublication network (green = approved, amber = contested, red = rejected, gray = not in the trust state), read via a federated SERVICE call to the trust repo. Below the diagram, a status line summarizes the central agent's own trust state: approval status, minimum depth from the trust seed, number of known keys, total trust paths, and network share (ratio). Names are taken from the canonical trust-state names where available, falling back to names in introduction nanopublications; long names wrap to two lines. Retracted endorsements are excluded via the invalidation check on the endorsing nanopublications. Positions are computed via rank subqueries, so the output is deterministic.";
